I would be very glad to exchange some ideas with you, especially regarding as well the situation of fecal sludge, as I understand that centralized treatments often have low BOD due to the septic tanks. I wonder how fecal sludge management is done and if the sludge goes to the treatment plants.
As well I would like to learn more about the wastewater refinancing.

Thanks in advance and I will contact you by email as well. Just wanted to let the comunity know, just in case there is sombody else who could (or would like to) contribute with knowledge about Thailand maybe.

Treatment process components by Sustainable sanitation, on Flickr

One of the Caltech prototypes was presented connected to ERAM’s E-Toilet interface. At the top of the container (which houses the toilet) you can see a black sheet sticking out. This is in fact the solar tar sheet - works like solar panels but is far less by Sustainable sanitation, on Flickr

This last picture might be an "old hat" for professionals working with solar power. But for me it was a new thing: it replaces the former fancy solar panels with a black "solar tar sheet" (what is the exact technical term for it?). It looks very simply but is probably very complex inside. Seems like a wonderful simplication though and less prone to theft and vandalism?

Thank you for your introduction and your post and congratulations to your work.
I was watching the video were you described the systems in detail.
Could you give more information regarding how far the goals of the RTTC grants will be reached by then (www.susana.org/docs_ccbk/susana_download...y-2013-version-2.pdf):
Create a toilet that:
- removes pathogens from human waste and recovers valuable resources such as energy, clean water, and nutrients.
- operates “off the grid” without connections to water, sewer, or electrical lines.
- costs less than 5 cents per user per day: the anticipated capital and operational cost for the final products (commercial units) is expected to be less than $0.05/user/day, both for the family and neighborhood solutions1.

I would be particularly interested to know what happens with the residues. You mention that so far you did not observe any accumulation of solids in the anaerobic reactor. But in a long-term running system you may will have. What is your approach for the solid part regarding “recovers valuable resources such as energy/nutrients”?

Kind regards

Unlike water provision with a well established demand profile sanitation is a complex with behaviour and taboo at its foundation and for the market to be able to develop in poor countries requires an understanding of what these people are experiencing on a daily basis. Surely a personal toilet would be great to have and all humans aspire to this surely. But toilets will never be the top priority if food, clothing, housing, power, lighting, drainage and transportation are not solved. Add to this education, training and livelihoods as prime stepping stones and sanitation and solid waste for that matter will remain on the waiting list for local action plans. So my message is to integrate sanitation into the mosaic of development and to present it in terms of choices based on functionality - including the entire chain from user interface (the toilet) to storage, transportation, treatment, reuse and disposal. That means the sanitation system needs to be communicated and marketed and the net result is what will be worth investing in. Development is a struggle and a lot of this integration starts at home, at school and at the local level where the system can be seen functioning, providing health and environmental protection.

A question worth asking however is whether sanitation has actually been a market success in the developed world. Maybe on paper it has through the fee structures and presence of water utilities. But among the users especially in cities, this is a service no one really sees on a daily basis nor understands. And when it fails to function properly, we are ill-prepared and highly vulnerable. This says to me that to build resilience in this sector will require much more communication from the ground up and a declaration of performance much like other business and service sectors provide. It's time to take sanitation out of the closet on a global level. Without this we will continue to see 2.5 billion without proper sanitation, 4.2 billion without functional sanitation systems (including treatment), the 1-2 billion with helminth worms, the 1 million child deaths, the girls quitting school at puberty, etc, etc. And there is so much ignorance to deal with in the North and the South. There's no dialogue, no learning.

This is why I congratulate BMGF for taking on this challenge in a multi-faceted matter to get this, the last chapter in human development on track. Let's all get involved and get this chapter right.

However, you will see these systems operating in slums earlier than you can imagine! It is the wrong debate to pick one systems and try to make it fit for all categories of customers. This is what has slowed down progress in sanitation so far and led us to this big failure! For the last decades, we would convene to debate what how cheap the latrines should be so that we can serve a large number. If had focus our efforts on selling services, we would be more successful as a community today. I visited several families who bought a latrine for $50-75 but have to pay $100/150 per year to maintain them!!!!!

Our approach, under the reinvent the toilet program, is to put on the market the next generation of technologies that will allow services providers to commercialize solutions (technology and services) that people want to buy and use. Some of these toilets you saw at the Fair are cheaper than Satellite TV connection and current septic tanks!

We will be successful, as a professional community, if we all focus the discussion on quality and affordable service provision and how to organization sanitation service delivery as a utility service! SuSanA can help with this if thematic groups can propose clear tools that drive action. For example defining requirements for service provision, standards, and developing template tender documents which allow entrepreneurs to compete for service delivery. I saw several industries in India with great toilet solutions, but no market penetration opportunity for them. It’s the case in Kenya, South Africa and many other places. Our current approach to promote sanitation is simply wrong. People don’t have toilets, industries are designing great solutions, but don’t have market to sell them! Why? Because we are not able to structure properly an industrial organization for better and competitive services? The need is more than urgent! There are great examples that can inspire all of us. The Kenya Water Services trust Fund, The Sanitation Utility – ONAS – Senegal or examples from, WSUP, WfP South Africa through work funded by WRC that demonstrate that we have enough evidence today to organize sanitation service delivery as a utility service, that works for all, Girls, Women, disables, poor, Schools. Several Donors (WB, ADB, AfDB) and investors have shown interest to support this emerging industry.

It is time for action. I mean concrete and measurable action so that we can solve this in your lifetime ! I challenge you and the SuSanA community to take on this bet and you will be surprised to see that all these Industries have viable solutions. We need a new approach to make significant impact on the lives of billion people. Let’s stop the debate on what technology is best (Investors, customers and entrepreneurs choices will drive this), and focus our attention on defining the right market structure for affordable utility services for slums and all other communities. Today, we have a viable range of industries ready to fill the gap if the market is structured for them! Hope you and SuSanA will contribute to this.]]>

The Loughborough team is led by Professor Sohail who can be contacted at This e-mail address is being protected from spambots. You need JavaScript enabled to view it

Professor Sohail wanted us to add the following: The project is in its development stage and the technology in the video should not be copied by inexperienced people; accidents could occur with the high pressure and temperature process.

A few comments on this technology and similar “high tech” treatment systems, if I may: Some of you might say this sort of advanced technology can’t be realistic, especially for developing countries. But it is the principle and mechanisms in these projects that are of relevance and where the breakthroughs are found. Building a single unit with this sort of equipment doesn’t seem financially competitive, but even this type of system seems to be meeting the BMGF criteria if it can run for say 25 years and there are several families connected. Such systems can also be used in hospitals to treat entire wards where patients are on heavy drugs. The principle of pressure and heat will also be useful to take all food and faeces from apartment blocks and hotels that are near sensitive coastal zones or are not allowed to install septic tanks or are not connected to sewer grids.

As far as slums are concerned this approach will probably never be affordable at least during our lifetime. But once oil is no longer affordable, food wastes will become prime fuel sources and such systems will pay for themselves, much like biogas systems do today.

Arno

Also, contrary to you statement, land application is very much rampant in Europe. The push to land apply this material is growing worldwide in response to its ever increasing volume (thanks to an exponentially growing population), the high cost of landfilling and due to rapidly shrinking space in landfills.

Finally, while I understand your point about limited resources, I am confused by your blanket unwillingness to adopt even the most rudimentary steps to ensure that something is safe before implementing it. Hasn't a blanket refusal to address the latter put us in the position that we currently find ourselves, namely at a point in time where rates of industrial disease are skyrocketing, hundreds of species are being rendered extinct every day and global temperatures are in chaos? Looking back in history, the mindset that has us rushing into rolling out "solutions" usually ends up producing a host of undesirable and unexpected results, which many times cancels out any real or perceived benefit. Don't we owe it to future generations to be a little more cautious than we currently are? I think they deserve it.]]>

dx.doi.org/10.4314/wsa.v40i2.9
www.wrc.org.za

Abstract

Dry sanitation requires the handling of faeces, which vary in age and degree of transformation. Rheological data are necessary to support the design of equipment to handle faeces. The rheological properties of fresh human faeces were measured using a variable-speed rotational rheometer. Samples were further tested for moisture content, total solids, volatile content, and ash content. Faecal samples were found to have a yield stress; there was a decrease in apparent viscosity with increasing shear rate. For any given shear rate, higher apparent viscosities are associated with lower moisture contents. Across a range of water contents of 58.5% to 88.7%, apparent viscosities of 27 Pa∙s to 2 014 Pa∙s were measured at a shear rate of 1 s-1. During constant shear tests, the apparent viscosity of all faeces was found to decrease asymptotically, where the
minimum apparent viscosity value increased with decreasing moisture content. A structural recovery test indicates that human faeces are thixotropic in behaviour, where the viscosity permanently decreases to 0.5% of the initial value after a 20 s exposure to a shear rate of 10 s-1. A linear relationship between viscosity and temperature was found, with a recorded 30.6% decrease in viscosity for a 35.6 °C increase in temperature from 13.4°C.

This data will be of use to designers wishing to design faecal transport systems for dry sanitation systems. The shear thinning nature of the material should be of no surprise (and of some relief)to readers.

Further work in this area is currently underway. Studies include

  • rheology of sludge at different depths of dry VIP latrines (individual, communal and schools)
  • rheology of sludge from pour-flush leach pits

Eram Scientific has received grant for developing Cost effective & sustainable eToilets by the Gates Foundation supported “Reinvent the Toilet Challenge: India“ ( RTTC – India) for specific communities such as slums. This research will involve ‘field testing of off-grid, self-sustained, modular, electronic toilet for large communities, with solar energy for Indian weather and integrated with mixed waste processing unit, with water, energy/ fertilizer recovery. RTTC-India is a collaborative effort of the Department of Biotechnology (DBT), Biotechnology Industry Research Assistance Council (BIRAC), Govt. of India and the Bill & Melinda Gates Foundation. This program is an India-specific program modelled on the Gates Foundation’s global Reinvent the Toilet Challenge (RTTC), under which Eram Scientific has been already awarded grant in 2012.

ESS is considering to collaborate with California Institute of Technology (CALTECH), Duke University and University of South Florida (USF) to integrate various models of eToilets with the processing units of the international collaborators and test the combined systems in several locations across India.

Dr Siddeek Ahmed, Chairman of Eram Group received the award certificate from Prof. K. Vijay Raghavan, Secretary , Department of Biotechnology, Govt. of India at the “Reinvent the Toilet Fair: India”, an event held in New Delhi during 21st & 22nd March 2014.]]>

Interview with Bincy (5 minutes):



Technical tour of their 3 exhibits (9 minutes):



Points that I found relevant:
  1. The company Eram Scientific is registered as a for-profit company but it is a Social Enterprise arm of Eram Group, a large Indian company. Eram Scientific gets an income from the customers of the eToilet to cover part of the costs, but it is not yet making a profit.
  2. The toilets are rather expensive; Kerala is a state in India which is relatively wealthy (Kerala is the state where they are installed).
  3. They were already implementing this before they got the additional money from the BMGF. With the additional money they were able to do additional research on the self-cleaning properties.
  4. The self-cleaning properties are very important to them, at the expense of using quite a bit of water, e.g. for automated floor cleaning.
  5. The treatment side of the wastewater generated from the toilets was so far not in focus; conventional technologies were used, mainly connection to a sewer. Now with this new research grant they will connect it to the anerobic membrane bioreactor developed by Daniel Yeh's group (University of South Florida, see forum.susana.org/forum/categories/98-res...-now-in-kerala-india). This is also not that cheap and not that simple, but the field trials that they are carrying out this year will reveal more.

Bincy, Daniel and Robert, please correct me if I have said anything wrong about your project. Thanks.

Eram Scientific unveiled the first-ever eToilet Imperial Model during the Reinvent The Toilet Fair held in New Delhi, India on 21st & 22nd March 2014. Along with this, eToilet School Model and General Public Model served as frontend systems for the treatment units of Duke University and CALTECH. Eram Scientific Solutions’ project was one of the 50 exhibits displayed during the two-day fair.

The Reinvent the Toilet Fair: India aims to stimulate discussion and spur partnerships to improve global sanitation and bring affordable sanitation solutions to people who need it most. The fair is also an opportunity to recognize India’s leadership and commitment to improving child health and fostering innovative solutions to persistent development challenges. The fair is also supported by the Indian Ministry of Housing and Urban Poverty Alleviation and Ministry of Urban Development.

The Imperial Model offers salient features like:

• Coin/Card based Access Control
