Kind: captions Language: en don't okay for me another okay oh another one two minutes maybe so okay i might leave me before we start the session please good morning to all the participants let me introduce myself again my name is as your house for today and for this session we will be moderate by professor chandra city and today we have a very interesting interesting interesting topic it's about emerging technologies and on-site wastewater treatment that will present by professor okay before we start we before we proceed to the lectures uh i will allow me to show to the participant first about more about uh professor contacted but his biography so uh there is a gentleman so professor thomas is a professor of the environmental engineering management of the asian institute of technology thailand he is an internationally recognized professional on fecal sludge management sanitation systems and wastewater treatment technology his major scholarly contributions include publications of more than 60 referee international journals papers 3 books and 9 book chapters he has invented sanitation technologies one of which is added to his credit and several uh feeling he has joined jointly develop a professional master degree program in regenerative sanitation and method 18 doctoral students he has secured significant fun projects including research and training grants and most notably the bill and belinda great foundation grants on decentralized wastewater management in developing countries design operation and monitoring it has contributed significantly to capacity building in fecal sludge management and decentralized wastewater treatment systems in thailand and abroad including capacity strengthening of policymakers so uh that was about uh professor tamarkotta so uh without wasting any more time i would like to give the session to our moderate moderator uh professor chandra said you may proceed okay uh good morning so so i surely study the picture of professor tamara because he is a big fan of the liverpool and this year he is the the champions the league champions so uh you'll never walk alone so uh professor tamara is a friend of mine so we will proceed with uh his lecture via uh has been uh mentioned by ahmad saudi his lecture is about the emerging technology on on-site uh with visual treatment uh for domestic visual treatment uh uh tamara you will control by yourself for uh the presentation uh you are still on mute okay you control by myself okay okay please go ahead please the time is your camera okay so telling makassi and telemachus the participants that joining me to celebrate the champions league thanks a lot for that anyway i will try to give you the ideas of that what would be the so-called emerging technologies on the on-site wastewater treatment system in my opinion and or in my experience as well okay you can see you can hear me well right yes yes great great very nice so as introduced by that we have involved in the quite sizable brands from the building melinda gates foundations that the name of the program is about the reinventing the toilets program which i'd like to share with you that how should we develop and how should we consider the technologies to be further developed and applied then i'd like to also address to you that we need to talk about that sanitation step in particular to the on-site wastewater treatment system or the centralized wastewater treatment system we need to achieve the sdg sdt6 in particular which i try to propose to the the society that simulations we can reach up to that simulation 4.0 as well similar to those the industrial license or some others that we need to step up not rather than just having the toilets but we need to think about that how you should improve the system is better then my key outlines for today discussions or the presentations and then of course your question and answer from your site would be very important as well that we can discuss about the the unveiled sanitation challenges is that very important at least to my country to my opinions that uh quite similar to indonesia and some other developing countries we remain lots of challenges that we may not be able to achieve simply by having a new pipes a new treatment system but we need to think in a way another way around so that he highlights would be about the innovations and emerging technologies that's very important for us to talk today that how should we develop innovations or we just think from the technology point of view that well we can use the the spaceship the toilets applied to the slum in the jagada or in bandung but is that applicable applicable and also acceptable to the users or not that we need to think about what would they mean by innovations and also that some other emerging technology is that applicable to the the low income societies or not the last one i just like to address to you is about that the wenger is to overcome the sanitation challenges whether our emerging technology on the westward treatment system can overcome the sensation challenge or not or do we need the others ranges as well rather than just thinking of that well we have to better toilets we have a better onsite treatment technologies whether it is enough to overcome the sanitation challenges or not that which would be the room for discussion further and i would propose some idea that what would be the wedges then just talk briefly about this std6 that we may like to discuss about that 6.2 and 6521.6.31 that talked about the open application and improve quality of base water treatment and sales reuse you may have impressed that in thailand we achieve the mdg the millennium development goal not sdg quite successfully in the past decades but if we look into further details just like to share with you that well from the statistic we said 99.5 we have the success in providing the toilets or the safe toilets to the people in the 19 by 2009 then most of the toilets would be powerful system whereas only in the urban city this relies on the plus flexing system or the flash tank system that from the toilets and then the most of the cases in the either in urban or in the urban or the rural area really lies on the cesspit cesspool system whereas we use very few the commercial package or the treatment units but that would be only for the new housing asset will install such a system then if we talked about the domestic wastewater management in thailand in particular about 10 million cubic meters a day produced from the about yet a thousand local administrative organizations all over the countries we have 77 provinces and then the local administrative organization we have many more but even we said we achieved mdg in 2009 but we can install only 105 centralized wastewater treatment plants that in the year 2018 and not so lucky that about that 105 treatment plants only 60 is functioning whereas the other 40 uh plants is not so functioning well so that they would have just a porn system like the the fish ponds but no one taking care of the ponds then it's not that functioning as we propose to be then it is invested already based on the government budget also the loans also from the the the clients from many of the donors we invested already 1.8 billion u.s dollar for such a centralized treatment system then the capacity of the 105 trillion plants we can treat about 2.6 million cubic meters a day from if they if they're functioning well then it means that the remaining every day is about 7 million cubic meter a days we did charge without any treatments to the environment in thailand and majority of the treatment system as you can see here that majority would be the stabilization pawns the various conventional traditional technologies that we use in the rural areas and in the city we may use active dislodge and some use that elected lagoons and then based on that we can say that well it's not successfully practiced to to cover all the treatment plan and after the 2018 so far until this year we haven't heard any new investment from the government or from the development banks that they would like to expand more so that we still have a huge challenges to to cover on this if you would like to meet sdg in the year 2030 but anyway another problem i'd just like to share with you and this would be uh for most of the country if you talk about that on-site treatment units so if you thought about that on site treatment system like the cesspool septic tank or commercial septic tank that's available in the market it is to me it's just a kind of a storage and then waiting for someone to empty whereas there would be a certain liquid efferent that can connect to the combined silver or the drainage system that can discharge but whereas the majority of the pollutions the pollutants here in the septic tank remains for removed by the empty services if you have the the good system like the truck then the empty truck or the wacom truck can empty it for you but if not many in the slum area you still on the manual emptying services which is not that good at all and that's not that good if you just use that truck to empty your toilets but you did charge right away to the water bodies then the if you are good enough you should have the fecal sludge treatment plants once you have either the treatment system or on site treatment system you need to provide how should we manage the sludge you collected from that treatment system as well or either to provide acid the fertilizers or applied to the farmlands that that would be the things that that we would wish to go but uh unview sanitation just like to share with you that uh as we mentioned about that 10 million uh cubic meter a day so majority of the treatment plans is not covering the treatment system but it is about that 27 or 30 percent at most but the remaining pollutants here from the toilets it would be from the cesspool from a specific thing that the majority of the pollution will go spy the record trucks whereas you can notice here that almost 90 percent of the trucks it collect the the sludge without any treatment and then they just ditch us somewhere somehow on the land to the rivers to the canals and then that could cause a heavy pollution as well so if we talk like this to the the sdg it we will not be able to uh claim ourselves that we will soon comply with the sdg that yeah if we talk about sct we have to manage properly all the sludge here as well rather than just thinking of that center light treatment system and if you would like to divert the the system on the onsite or the other design system to be the pipe or the silver system then we need to stop using the commercial setting tank on the cesspool but i'm sure that it would be the same as in your country in my country and in other southeast asian countries so that once we install the drainage or the silver system we still use this kind of uh on-site system that only the liquid parts will go into the civil system so that would be the the the sanitation issues or the challenges that we are facing so far then that's why just like to to share with you some ideas that what would be the solution and the solutions for the toilets for the pita trees for the septic tank for the sewerage would that be okay or not as we have uh study in the textbook in many of that the handbooks are so called that well if you have the hankin toilets you just provide the pig latrines or if you have enough money for the septic tank if you have more money go to further zero system but there would be many other issue upcoming issues like um what what about the flow orders or the safety assets if they have to use like that so the conventional solution may not be the the the solution for all like if you just copy the similar system that used in japan in europe to provide more and more civil rights system the question would be up to your government that you have enough budget or not on the the municipality that you have to talk about hey you have enough budget or the donor would like to give you the loans for this kind of system or not so that would be the question so we need to think another way around but anyway if we talked about that the total pictures of the uh ancient uh sanitation which still relies on most of the the the decent alliance on the on-site system system either in thailand you can see that 83 percent of the equipped acetic tanks or in indonesia you said about that at 63 percent equipped with the septic tank so that that's still there whether we just stop using the septic tank and convert to the the big central treatment plants as mentioned by the person marcos that well it could be but what would be the cost what would be the investment to do or you may like to slowly improve your septic tanks to have a better treatment for performance and then of course you need to taking care of that the fee costs as well so that would be the the the issues or the challenges or the word the reasons that i would like to share address to you then that's why we have to talk about data from the emerging technologies how should we in the way that or reinvent our technologies from the existing technology we have so we should not just talk about the technologies as on science or off-site or the silver system or non-civil system as such but we need to think about that the value change from this sanitation revolutions if you propose to go for the civil rights system you may need to think about that well if you connect to the brother closest then connect right away to the server and bump into the chipman plans yes ideally it would be nice like that but the course and also that if it is a new city new town new urban area you may be possible to do that simply but if it is a kind of city like in jakarta or in bandung should you convert the toilets and then connect right away to the silver system it's not that easy at all well how should we improve here that form the the containments we have assessment cesspool or the septic tank and then how should you have the better collection system together with the treatment plan and then that would be so but we need to have the better fico treatment system from here as well so the question here would be that whether we have to go for the innovative or the process or the contentments you may have seen or you may have heard about that uh uh during migration toilets or the zero flush toilets or one liter flush toilets that would be nice but whether it is acceptable or functioning in the practice or not that would be the things that we can think about innovations all the containment is as well the septic tank mostly is used for contain the sludge and then not really having a function of the treatment whether we can improve the treatment mechanism inside the septic tank inside assessment cesspool or not so that the the loading to the emptying or the collection services could be lower or even the truck itself whether we can have a better or how we can have the efficient trucks in the with the equipment and then with the treatment plan as well rather than just using the the centering base and then applying for the fertilizers what are the other technology like convert into the bell gas or to the biodiesels is that possible or not so that would be lots of room for improvement that the emerging technology that we can fit into these figures then that's why the mdg and sdg targets we need to comply with that would be your ideas or your vision to go aside from your countries whether you just like to go that convert or the city every city to the civil cities or you still relies on this kind of on-site and with the fecal flux treatment system and then you can achieve the targets of the sdg that's up to you to choose but i mostly believe that most of the developing country will still reliance on this on-site or decentralized treatment system together with that because management system we cannot just change right away to the civil system which is very very costly in investment and no revenues to be generated that you see from the civil system so that's why the ideas for innovation in emerging desks to come from the containment from the toilet itself from the collection system and from the technology points then uh i'd just like to share with you some ideas that we have discussed in the past and then taking books thinking about that from the toilets apart from the low flush on dry products if you can have the anti germs or dog free that would be better or not for the dry toilet system and how can we integrate this kind of disinfection technologies in the toilets and then we will have less problem to the collection system if we would like to apply right away for the fertilizers so that would be the things another one would be that if you use a dry toilet mostly the complaint would be from the order but how we can ensure that there would be older odorless toilets that that that we should provide as well from the containments or the simple suspicious system i'm sure that most of the areas in indonesia you still rely on that but whether it is just functioning as the solid separation only or whether you can improve or enhance the digestion process inside the septic tank or not or whether you can reduce the odor or better to compose as well for the sludge for the organic content inside that in the truck as well we mostly relax on either the the six uh six cubic meter or twelve cubic meter trucks that uh from the japan or from china that produce but whether we can uh reinvent into that a smaller size that accessible to the very condensed area like in the slum or in the dense area or with the higher pressure or satellite units should there be any kind of processing unit inside the truck natural that we can talk about that later and in the treatments of course the low cost would be ideas for the emerging technologies and then further to that we need to think further about what would be the values of your buy products apart from just to meet the standards i'm sure that indonesia you're also having the standards and later you may need to go for the more stringent standards but it doesn't mean to do just to meet the standard but if you can define better values of your by products either in terms of the gas in terms of the liquids then you can get the returns of the investment and of course now today the germ-free would be very important like the corona virus we also identify that many of the dna of the virus that can be determined by the effects of the septic tank or the treatment plan as well so that would be the room for innovations but i just like to give you that some ideas that in the past not only from ait the building that gets for the asians they have invested all over the world that the best researchers the best scientists that are you should reinvent your toilets you invent your treatment technologies so some ideas that you can go into inside but i'm not be able to to disclose everything because that would be some kind of that the patent issues of the technologies the cortex they selectively use this kind so called electrochemical system to oxidize the wastewater ideally that would be very interesting as for that instead of using a simple biodegradation process but if you can enhance oxidization process throughout the electrochemical system then you can get the better the bowel degradation and at the same time you can produce the chlorine from your chloride in your urine and then you can use for that disinfection process so that would be some idea and then they are now in that in a way which to to to get into the commercial products with the chinese partners in in china and then they also try to use that solar panels as well if it is used that much of the electricity in the production or in the operating of the electrochemical system then that would be some hints of the system that they can use for about up to 500 users per day so it may not be [Music] good enough yet for the household system but it would be good for the public toilets or the school or the big the medium scale of the household system then if you would like to get into more details you can get into this link that what would be the detailed design of that but of course they will not disclose at all because the all the technology it is already attended and then they transfer the technologies to china and hopefully that with the chinese manufacturing skill we can reduce the cost of investment for these electrochemical distribution processes then the other one that you may have seen many many uh video clips from the builder case themselves or even mr bilquez himself he has demonstrated many times that why don't we use this kind of products to treat at source right away so that cranfield university my colleagues up there they use so-called nano membranes to remove the dirtiness of the toilet waste water and then they use so-called that the dry system but the dry system is not very dry because they use a kind of an unknown coating materials that all the fecal matters be not attached to the toilet bowls so that you can remove right away and then you can even palletize or classify the gas or the liquid parts from this couple of technologies so it's still a good process that you can have very good ideas but to come up to this kind of industrial design process that would be interesting parts that you can get much into detail said well why don't we integrate all the possible technology into the small scale that that would be the things that apart from thinking of only the active slash the concerted wetlands or why don't we use this kind of uh even up to membrane that i'm sure that process chandra will talk to you about the membrane that mostly for the drinking water equipment system but why don't we apply that even the nano membrane and then with this kind of a unique waterless system then we can process into one but of course the cost would be still the problem and then the other one would be that the people acceptance of this kind of products if i were the user of the toilets i once i sit on the toilets i would have another things to think about that well whether it will be having a certain bombs or exposed or we have the electricity running down here with the screw then whether we trust me myself or not then the acceptable uh acceptability of the the the users of the toilets would be another things that we have to discuss later but the idea would be very nice and then we can make use of this system then the other one that's from the the usf the university of south florida that they use a bit more simple technology that's so-called anaerobic system but they integrated with the membrane bioreactors i'm sure that many studies in japan or even in indonesia you have heard about that membrane reactors but if we can scale down those kind of anaerobic membrane reactors that also potentially to reduce the the solids and then to produce the gas after the bioreactors and then the treated effluent can be go through the the throwing of that the plant as well so that's the system so called the new generators they're applying the key features would be that the android membrane reactors with the hydroponic system the hydroponic system that would be a very interesting part as well that if we carefully consider the minerals or the nutrients remain from out of wastewater it's still very very high values so that if we can grow a certain of that the plants i'm sure that the vegetables would not be recommended for this hydroponic system but decorative plants we can design whether that used and then the biogas we can be used with the digestions and outside the system as well for cooking and heating but the design is more important that how we can reduce the size and how we can fabricate into the industrial scale then the other one that's toronto uh university of toronto that have been using and use that's a kind of so-called continuous turmoil cue that or the things that instead of waiting for the korean or some disinfectants but there would be a certain heat that we can generate from the process and then you can have that process in working for the piston and the prosthetic pumps to the reactors and then with that kind of external heat you can kill the germs and then you can reduce the moisture inside your fecal matter and then you can reuse right away so this would be the kind of prototypes that are very impressive when i was at the the toilet expo in beijing that showed to the mr bukit says so that well you can having a kaiser called a separation device from this as a squad player and then plastic pumps and small rings processes so the key feature would be here that the smoldering process is that you can process the fecal matter right away with the heat productions then you can generate the the energy from your fecal metals right away and then use that the so-called catalytic conversion and then generate more heat and then cover all these kind of processes in the units but the only thing is that that what would be the cost not that if we apply that kind of uh so-called f1 technologies but of course it could be quite effective you can kill all the germs you can kill all the uh the the problems of that even the the bad smell you can generate up to that uh right away from the system you can get the kind of a so-called charcoal like a charcoal from the system that you can produce the other one that you may have heard a lot for the application of the microbial fuel cells but this is interesting part that from the bristol university that they have used that microbial fuel cell to generate the electricity from the toilets which can generate energy enough for operation of the toilet system itself so with that kind of uh modernized mfc they call asset multiple mfc units that can uh generate and then especially for the public toilets you may have seen lots of that the male's rooms or the gentlemen rooms that we separate the ui nicely but why don't we produce electricity out of that and then you can even use for uh operation of the toilet system and then that could be very simple but so this would be the things that we can think over the thing that how we can having the higher values of your byproducts instead of using your urine for as a liquid fertilizers but if we can produce etcds then it would have more values that you can get more incomes or more revenues to go for your treatment system but anyway that's just kind of that the very fancy or very advanced technology just like to share with you but our ideas from aat point of views we got the money we got the brands from the transformation as well we thinking another way around that we need to think about the sanitation markets we have to think about the users or the potential buyers the perceptions as well otherwise we will not be able to sell or deploy the technologies into the markets so with this kind of product development stage diagram that we have developed in the past six seven years so far we try to think into stream that not just advance the technology as such but we need to consider the user perception or the buyer perception as well otherwise no one would like to buy our technology for example that from the toronto technologies from the technology point of view this is very fascinating but for the user perspective if we talk about the user saying wow whether it is having any uh harms when we use the flushing toilets into that or not or if you thought the flushing water can be maintained the system is not that easy but of course if it is installed into the into the spaceship or into the space stations that could be possible because of that one technology is that reliable but if you would like to apply that to the low-income society whether it is acceptable or not then our technologies from ait we have to study first like in the past we studied the market needs in thailand in vietnam cambodia to represent about that if we have two three different uh incomes levels uh and then different kind of a toilet system in the past what would be the needs how can we develop the technologies to meet the unmet needs that were important for us so that that we developed the technology in a way with that we so-called so-called hybrid research that we on on one hand we need to develop a technology so-called technology approach we try to define whatever the possible technology but of course we need to consult with the market researcher as well to define the unmet needs to define the customers or to define what are the real problems somehow would not be just to meet the standards but what are the other problems that that we can develop our technologies to emergency to meet the real problems so that we can get the innovation and then we can deploy the technologies to the markets so just to review the bit of the history of our technology evolution of this on-site transcendental system that we start in the idea generation to brainstorm to discuss many many people not only the engineers or the scientists in the field of water and solar system but we invite the the market researcher we invite the business developers to join hand into the brainstorm session that how should we develop the technologies whether we should like to go the same as the us or the european technologies i showed you in the past that hey we can go like that or not and then if it is doable yes whether it is applicable to our country to our cities or not then we come up with the idea that well we will not just to go very every advancement but we try to define the most possible technologies of course in the first stage the first two three years we have investors money for this kind of idea screenings but we come up to those skills to say that for example the solar system idea come up with the idea that well many people still realize or accept the septic tank anyway but if we can enhance the performance of a septic tank then we can the the market will be able to accept the units or the treatment technology much easier and we'll talk to that the other one ideas would be that to use a so-called cyclone separation techniques or technologies that integrate into the system then ideas would be that we will not go for the dry toilet system like the clean fuel system but we think about that uh either in indonesia and then we study in vietnam with cambodia thailand that no one would like to use the dry toilets they have explained in the past that even the very best uh the toilets the dry toilets from europe but uh from the long-term operation they still have the problem of the bad smell so we have no problem after the water uh that doesn't like that the dry countries in the middle east or in africa so that we still go for the the the flashing system that either the power flush or the flash tank then but under our idea would be that why don't we use the cyclone separation to separate the solid liquid parts and trees separately that would be the same idea as the urine separation toilets but we separate the the flushing water with our of the solid parts then if we can separate that then it would be more simple to treat the liquid effects on the solid parts the other one would be that we realized that especially for the low income society we still realize on that set speed cesspool the cement ring types not either in thailand but i'm sure that in indonesia in the philippines in vietnam we also use that for the rural toilets such but how can we improve how can we enhance performance of that certificate without any uh much of modification we think of that why don't we use a certain reactor to put inside the existing says processful system and then we can enhance the treatment performance we can capture the solid betters and then we can take it out so that that would be another i guess that would be the three main technologies that we come up with the the product developments for for the system then just to share with you first with the philosophy tank that you may have heard that this will be one of the outgoing technologies that we have and then i just like to share with you the video please check that whether you can hear the bell or not you can hear okay that's about the week of advertisement i'm sorry for that but the technology inside just to share with you the idea is that uh we have uh study starting from the lab scale pilot scale and the field scale that we modify the simple the solar or heat collecting system that i'm sure that indonesia you also use that very awkwardly but that simplifies the use of that heat exchange from the water system and then heat up into the the tank about uh 40 to 55 degrees celsius depending on the day time like night time we cannot maintain the constant temperatures but it doesn't matter it can function in quite well for the long-term duration that's where we have uh noticed so far then the uh the system that we have it is uh having the idea that we have the inside septic tank that having the inside part can so-called disinfect a certain amount of the the e coli on the pathogen as well because in the middle of the tank the temperature it would heat up about that 60 degrees celsius 60 to 65 degrees celsius then this can uh help disinfect a certain amount of the bacteria but the outsider of the portion of the tank the temperature up about to the 40 degree celsius they can produce the so-called thermophilic valve degradation that would be very fast verification process so that apart from that having the better body cd removal the other things that we can ensure that would be that the solid accumulations inside the civic tank would be much smaller from the conventional septic tank then we have less problem of the fecal sludge as well from the point of that we can degrade more solid factors and fractions in the in the tank then apart from that we also need the more detailed research to do about that whether it is possible that we say it is thermophilic biodegradations or not and then we use the micro build techniques to identify the groups of the bacteria the groups of the mechanism we found out that many of them are the thermophilic mobile groups that can use a lot in the the regulation process and then we prove that the tbs the deductions it would be much higher than the conventional septic tank so that that would be the proof that we can have the system in operation and not only in the labs and we also having a long-term operation right now almost 45 years times already that we maintain the temperatures in the septic tank about that 40 degrees celsius then we have found out that the large accumulation inside the tank would be much smaller compared with that the conventional septic tank so that would be the idea is that that apart from having the better treatment performance we can meet at least high intentional standards but also that the user will have less problem of the emptying of the tank if you have uh using the conventional tank the same thing that we have you can notice here that the green toilets here we use the solar septic tank but the other one is not we just use a conventional simplification to compare right away we asked one families to use one toilet another family used another toilet then with the same size of the family used for over 2-3 years time we found out that the the conventional septic tank they have much higher the sludge accumulation that's mean that they have a burden to uh uh emptying the fico sludge so that would be our uh simple ideas but even if we say that the the cause would be much smaller from the technologies that i have presented to you from the u.s from the european technologies but still it's quite high about that 2.5 thousand yes dollar but comparing the card system even if they said they used the chinese partners to reduce the cost more than half but one unit for them is about that fifteen thousand us dollars so that uh our solar city technology would be more compatible to the uh to the markets and then we can meet the same standards on that so that would be the course and then of course we have uh showcase and then we have a demonstrate that the real application is not that only from our labs at the ait system but we keep it monitored for long-term operation to prove that it is functioning quite well as well then the other one that's so called a cyclone toilet and all the cyclone cube that you have heard about that so we designed this kind of cyclone system in a way that you can efficiently separate you notice here that there would be several design of the cyclone q we used cfd we used the real practice of the uh the the system to test and then uh to also to use a simple or the correct uh the fecal matters uh samples that [Music] the toilets and flush it out whether it can separate right away or not we found out that if we design properly we can separate more than 97 of the liquids out of the the solid parts so that would be the ideas that we can use and apply that but of course i can disclose that much to you this is also the patented technologies and the other things that we also apply that not the same as the professor michael hoffman from the cortex but we simplify the use of the electrochemical for disinfection only we are not using the electrochemical for biodegradation process so that we can reduce the cost so that we can simplify the control of the materials we don't need to apply the advanced metal materials in as a cartoon anodes for these chemical distributions but within only about 15 to 20 minutes we can kill all the germs with our simple design of the eukaryotic function for the liquid parts so with that we also have the same kind of testing we having many many design this is one design that we use and then we have uh testing it's not the same as in the lab scale i'm sure that in itb we also have plenty of the collapse scale on the pilot scale but in the field scale we have found many many of the the operating issues that is for it doesn't mean the same thing like we expect only the the the fecal matters and flushing water but somehow the people or the users use the toilets with the very hard to degrade papers as uh the wiping papers as well so somehow it clogged or it is it's caught into the units not locked into the the separator itself so we need to break break the units and then we do all the design and many things from that then successfully we can transfer our technology to the scg chemicals i'm sure that you know scg is very well one of the biggest companies in thailand for the plato chemicals and then also i'm sure that they invested lots of things in indonesia so they accept our technologies and use that because that's why i cannot disclose that much of the technology inside to them that they having another uh developing partners to help in the scaling up that all the commercialized the technology into uh commercial scale so that would have the up to the level of the so-called tr the technology readiness level they said it is already up to eight which is this mean that product available so that they can use for the 10 user per days and can have a life expectancy it's about that the 10 years and then they can meet the standard of the iso 30 uh 500 standards i'm sure that you in your country you may have heard about this but i don't think that indonesian adopt the iso 3 30 to 500 standard yet but anyway it's the future is that if you can meet the standards then you can sell all over the countries and ensure that you can get a very nice one the unique idea is that from the transfer technology with the commercial design with the industrial design they have the better design in a way which that our cyclone and then they have better treatment with the more portions for the treatment like uh equipment the micro bubbles equip that the anoxic conditions and then they can operate in a way that they can meet or the standards and as i earlier mentioned to you the iso standard this is very very stringent i'm sure that much higher or much stranger than our national standards for example that they require the tn removals much more than 75 and also that the ecoline it should be zero so that you have to ensure that it's not just meeting the national standard but that this system would meet the iso center so that that is uh the the technology is that they are working out and then soon to to launch into the market and then i have heard that they will try to uh do a kind of fuel scale testing in the indonesia as well i'm not so sure where but they will be developed because they have they define the potential markets in indonesia to launch this technology in in the in the market then the other one that just share with you some brief idea of the cess to fit technology is that i have said to you that it would be very simple that we try to develop the bioreactors inside the existing suspicious for the cement ring that widely used in our southeast asian countries so we prove of the concept and then in the lab in the peloton we found out that it would be very nice to use that the other things would be that well this is not a big market because this is for the poor people then no one would like to accept the technology or transfer the technology to the market yet but to me at least this is quite an interesting part that if we can define that certain technologies that we can improve the existing system that we have we know that the septic tanks or the suspicious it doesn't function as a treatment unit it is just only for containing a certain period of time after the sludge and then waiting for the tanker to empty it out but if we can improve the treatment of months it would be very effects to the efficiencies of the sanitation system so that would be the things that we are working out and then try to promote more and more that the access to fit would be the right way to go or the emerging technology is that we can indicate better but of course we cannot integrate that to advanced technology otherwise it would be too expensive for the poor people to accept the technologies then the the question would be to you and to me as well that whether these kind of new toilets on you on site technology can overcome the sanitation challenge or not as the developer said the researcher most of you we are too busy we will go more and more details of that the technologies of the the chemical system ecto chemical system the solar system but we may overlook some other things like fecal slash management issues so that would be the big question mark that not just on on-site system or the on-site decentralized treatment technology we need to think about that the fecal sludge management issues as well that very very important to my views so in general we can say that the fecal sludge will generate about that 200 to 300 gram per person per day and then in indonesia we have almost 400 million people just multiplied by that then that would be the size of the because that generated per day and then you need to manage i'm sure that that would be the huge issue that's why that it would be not really comfortable to disclose but we have to promote it more and more especially our developing country is not the the the way to go for only the advanced technology for the on-site system but we need to improve the vehicle management because management systems as well to ensure that it would be not having a problem because uh if you have heard about this because slash concentration is much much higher than the domestic water or the municipal wastewater we receive i'm sure that most of your treatment plans around the indonesian cities you will may not be able to get the body up to about 800 or 2000 milligram per liters but it is possible for your fecal sludge that would be very very high and in addition to that they would have much more equalized or much more helping accessible to spread into the environment if you do not have any better collection of better treatment system so that would be the huge problem at least to my opinion that we have to address more as well if we cannot change every people to use the better on side treatment technologies we need to emphasize here that yes we need to uh treat more and more better uh because collections so that would have lots of things that you have seen about that the virus bacteria the the producer from the fecal sludge and now today we found out that the viruses can stay longer in that the costly system my colleagues from the uk glasgow university he mentioned to me that the coronal virus would stay much longer if it is with the solid particles so that that would be another chance another thing that we need to taking care of well otherwise we spread again then the the virus or the other make organism will spread all over the world and then i mentioned that our developing countries we have lots of problem of the health means it's not only the biologists protocol or bacteria we still have a big uh microbial system like the helminth spread all over the countries as well and then in the sludge itself it has a very high helmet which can stay longer times in the toilets in the treatment technologies so the technology is for the fecal sludge i will not talk get into details because we have not much of time for that but the technologies that we have so-called conventional advanced up to that the hydrothermal carbonization or omni processors you may have heard from the guest foundation promotion that they try to promote the use of that omniprocessor also called not daily incineration but they call what the steep engine to produce the engine or to produce the energy out of the fecal sludge treatment system they have been tested in us in seneca and in china as well but it's still very expensive our country is still relying on this conventional system but you notice here that it's not really for this infection process so not very high efficiency to kill the germs from our conventional technology that would be another room to improve of our food cost treatment technologies but another way around that the things that just not the technology but we need to think about all the way of that local resources which is not really uh good business for the people just to advance technologies for example if you say that well we need to add more chemicals for this infection process to the system then it could be very costly how can we work with that on the locations where to be the the free course for treatment plans i'm sure that in indonesia you have to facing the plant as well that if you would like to design the uh westboro treatment plants no one would like to have that treatment plants next to their household next to their neighbors so that the location would be much more plumb if it is a few horsepower treatments and then the fecal volumes or the end users of that whether you can define that or not then we whether we need to reinvent or to think about that emerging a new collection and treatment system as well or not our ideas at aat we try to integrate into the collection with the treatments because we have the plum of that location because of we have no resources then we're thinking of that if we can advance the septic tank truck the septic truck to be uh having the treatment mechanisms why don't we can integrate that we initiate with this so-called sanitizer truck that we can have the simple solid liquid separation at the site it means that once you pump it out from the tank from the safety tank then you can separate the solid liquid right away and then you can uh discharge the solid liquid in the safe space or you can have a certain disinfection force process to kill all the gel or you can get it back into your safety can for further processes and then therefore the business point of views you can increase the number of the household that you can go now for the one day times instead of that only two three household a day you may get more than five or ten also a day for that so that would be our ideas for that we can increase and then this would be some idea in the past for the first version of this synthetizer strap that because to separate by using this so-called bio drum on rotating drum filters and then we can separate the solid and liquid parts and then the liquid can be disinfected and then so it will be dry by the heating itself inside the truck and then the volume would be very small i'm sure that the septic tank sludge the sludge percent would not be so high it would be about that maximum five to ten percent so if we can reduce the volumes then it means that you can use the truck more effectively into the further collection system then you get more benefits and then you can get more of course the the investment cost for the truck itself will be higher but you don't need any treatment plans if you can meet the standard so that would be our ideas too to meet and then you can get the fertilizer to go for agriculture right away if it is having the high temperatures most of the the germ will be done and then remains only the the organic parts then the the process is working still ongoing with the industrial partners of course atv may not be able to replicate this much or this size of the system but we are in a working process with the industry hopefully within uh next couple years or next couple months i don't know yet because of the call with our industrial partners say well we will not have enough money to invest more then our ideas would stop right away because uh we are also not capable or we have no capacity to do this kind of fabrications for our technologies but anyway just to share with you at the end that uh from the simulation the point of views we need to transform uh our sensation processes or revenues to be more commercially valuable and then the self-sustaining system in the past we just wait for the government wait for the donor to solve the problem for us in indonesia for sure th
