Thanks for your post about your project in Dakar with the SaTo pan.
I watched your video (which doesn't show the SaTo pan, but does show the Biofil toilet in detail) and I have some further questions for you.
But I think we should start a separate thread on that.
The project that you mentioned ("Provision of an innovative Biofil toilet system for flooded and flood-prone areas of Pikine and Guediawaye, Dakar, Senegal.") was mentioned last year in the forum here (call for proposals):
forum.susana.org/forum/categories/95-cal...ood-areas-in-senegal

And also here by Mbay on Page 2 of this discussion exactly one year ago:
forum.susana.org/forum/categories/99-fae...12&start=12#8824

Mbaye had said back then:
We launched an international tender and more than 20 bids were received. They range from traditional dry toilet to toilet producing energy and without sludge. The selection is about to be made and detailed information will be shared later.


As I always wonder "so what came out of your calls for proposals? Or what came out of the trials?", it is great to see your post and video. I will put some questions about your project into a separate thread, in order not to mix up things with the SaTo pan too much.

Regards,
Elisabeth]]>

Sherina said in that thread:

The SaTo pan has proven to be a really popular product for latrine improvement - both in terms of affordability and the benefits of making a latrine more hygienic, free from flies and safe for children. Since October 2014, SSG has sold over 2700 pans. SSG is identifying strategic partners through whom to distribute the pans both in the rural and urban areas which will help to achieve wider scale and impact.

This project was done by Biofilcom (Biological filters and Composters, Ltd of Accra, Ghana) under contract with the local office in Dakar of Oxfam/America. My firm was the project manager, consulting for Biofilcom.

We installed ten Biofil systems, which consist of a toilet with privacy enclosure and the Biofil biodigester, in private households. Some use your SaTo pans, others use flush toilets or the Biofil microflush toilet. They are located in flooded and flood-prone neighborhoods, which require the toilets and digesters being elevated above the level of flooding that occurs in the rainy season. These systems are presently being evaluated for suitability and environmental compatibility by Oxfam.

Thanks for sending me a sample to bring in Mauritania for my mission there trying to shape a sanitation marketing program in the desert. Hard job with population very poor, hard soil, small civil society, etc ... amongst other difficulties.

Almost none of the CLTS latrine that I saw were "improved". The heat makes them pretty odorless and there's almost no flies by 48°C. There's never a roof on the latrines so the VIP system couldn't work properly. No-one understood the need to close the hole with something and put some mesh on the ventilation pipe. The siphon is too expensive and for the cases I saw, either it was evaporated (less than 4 hours they mentioned) or people were unhappy because it consumes too much water.
The problems all come during the rainy season (August - October) when flies appear in mass and diarrhoea too.

Basically, they loved it in the field and there's a great potential in the sahel region but still in the program this seems complicated to organise all the logistic or spreding the Sato Pan in the desert.

Another question that I wanted to ask you on this forum so everyone could benefit the answer. Because there's no roof the pan would be exposed to high UV aggression, was there any test realised on the resistance of the SaTo Pan to UV ?

Thanks,

Ben]]>

It would be good to include this into a solid, lightweight, recycled-plastic outhouse to be used as an ArborLoo (over one shallow pit, then another, then planting trees). I even suggest building with no roof, as this would reduce cost, weight and smells, plus each rain would wash the floor and all surfaces, next the sun would help to sterilize them. (And the plastic could likely be protected from the UV somehow.)

It is also key to only promote this model where the soil is absorbant, the water table is low, and there is no flooding. In those conditions, it would be better to buiid UDDTs raised above the high water line.

Best wishes.
Chris

As long as we are currently involved in small WASH projects in Tanzania, I would like to check the possibility of testing the one being launched with Cresstanks in Uganda. It could be really interesting. Do you know how could I proceed?.

The version commercialized in Bangladesh was designed to flush with about 500ml, which is about half of the content in the most commonly used bodnas.

We have a new version being launched with Cresstanks in Uganda that can be flushed with 250ml or less.

Blue Diversion AUTARKY - A self-sustaining toilet off the grid (EAWAG, Switzerland) - by: SteffiE http://forum.susana.org/forum/categories/106-user-interface-technology-innovations/13529-blue-diversion-autarky-a-self-sustaining-toilet-off-the-grid-eawag-switzerland#13529 http://forum.susana.org/forum/categories/106-user-interface-technology-innovations/13529-blue-diversion-autarky-a-self-sustaining-toilet-off-the-grid-eawag-switzerland#13529
Title of grant: Blue Diversion AUTARKY - A self-sustaining toilet off the grid

Image to give you a visual impression (the pdf file in higher resolution is available here: www.susana.org/en/resources/library/details/2237):




  • Name of lead organization: Eawag (The Swiss Federal Institute of Aquatic Science and Technology)
  • Primary contact at lead organization: Kai Udert, Project lead and myself (Stefanie Enssle), Project coordination
  • Grantee location: Dübendorf, Switzerland
  • Developing country where the research will be tested: The current focus lies on process engineering and reactor construction. It is too early to think of field-testing, although South Africa might be an option.
  • Start and end date: 01/ 2015 – 12/ 2016
  • Grant type: Reinvent the Toilet Challenge (RTTC)
  • Grant size in USD: $2,826,507 (as per BMGF grant database)

Short description of the project:
“Blue Diversion AUTARKY” is the continuation of Eawag's RTTC project "Blue Diversion" (see here on the forum: forum.susana.org/forum/categories/106-us...and-and-austria#3692). In this new phase we will develop technologies and prototype reactors for the on-site treatment of source-separated urine, feces and polluted water from anal cleansing and handwashing.

The urine treatment reactor will consist of a first process step, in which calcium hydroxide is dosed to the fresh urine to increase the pH to above 12 to stabilize the nitrogen content, to precipitate phosphorus and to inactivate pathogens. In the second step the water is removed by passive evaporation techniques driven by atmospheric energy to avoid further energy requirements. The final products of the urine treatment are two solids; one containing all phosphorus, another containing all other nutrients and salts.

The feces treatment will be based on hydrothermal oxidation (HTO, also known as supercritical water oxidation SCWO). Its final products are water and precipitated solids. The latter contains all the phosphorus from feces. To heat up the process energy is needed once, it can be provided by a generator or a simple 220V power plug. Further energy demand is covered by a solar panel.

The water treatment reactor is based on gravity driven membrane technology (GDM) developed during the previous phases of the "Blue Diversion" project (see also in the SuSanA project database: www.susana.org/en/resources/projects?search=blue+diversion). The goal is to better understand and verify the safety of the system with respect to the user, and to explore alternative technologies such as activated carbon, ozone and UV light which may reduce capital and energy costs.

We are also examining how the same membrane technology functions in systems representing higher and lower organic loading as used in the toilets from other RTTC-partners e.g. RTI International (see also in the SuSanA project database the projects by RTI: www.susana.org/en/resources/projects?sea...h+Triangle+Institute).

Goal:
To develop a self-sustaining toilet off the grid.

Objectives:
Development of prototype reactors for the on-site treatment of source-separated urine, feces and polluted water.

Research or implementation partners:
- Eawag (Swiss Federal Institute of Aquatic Science and Technology)
- PSI (Paul Scherrer Institute)
- FHNW (University of Applied Sciences and Arts Northwestern Switzerland)
- EPFL (Swiss Federal Institute of Technology in Lausanne)
- SLU (Swedish University of Agriculture)
- EOOS (Austrian Design Office)

Project website: www.eawag.ch/autarky (under construction)

Related projects:
- www.bluediversiontoilet.com, the Autarky project is building on the results from the Blue Diversion project, especially regarding the water treatment.
- www.vuna.ch, the VUNA experience gives great insights about urine treatment and inspiration for the Autarky urine module.

Poster/flyer in English and French, as well as further documents in future are in the SuSanA library: www.susana.org/en/resources/library/details/2237

Current state of affairs:
Selection of one reactor set-up for urine, feces and water treatment.

Biggest successes so far:
Not applicable, project just started.

Main challenges / frustration:
Not applicable, project just started.

If you have any questions, please don't hesitate to ask me here on the forum.
