The question and answer session starts at time 25:16 in the same video. Stuart got asked some tough questions so if you are interested in this demonstration program in South Africa called SASTEP then it's well worth watching this presentation and discussion.

Here you can find the oral presentation and poster from FSM3 about the research projects from the Pollution Research Group of the University of KwaZulu-Natal, in Durban, South Africa. These research projects have been funded by the RTTC- Phase II.

The oral presentation deals with the study of fecal sludge drying kinetics in a home-made convective drying rig, which is able to measure on-line the mass of the sample during the process. The chemical and physical characteristics of the dried feacal sludge are also presented. From this date, the use of the dried feacal sludge as a fertilizer or biofuel is evaluated.

The poster presentation describes the rheological study performed on VIP feacal sludge samples obtained at different positions in the pit. Different characteristics are shown and discussed : flow curves obtained during shear steady and dynamic tests in a rheometers ; the liquid / plastic behavior determined in a cone penetrometer. The rheological properties of the feacal sludge were then related to the moisture, total solids, volatile solids and ash content.

Kindly,
Santiago Septien]]>

Dear Tina,

Thanks for making this post. I have a question about your presentation on:
Development of standard operating procedures for faecal sludge laboratory analyses: Tina Velkushanova, Merlien Reddy, Pollution Research Group, University of KwaZulu-Natal
www.susana.org/images/documents/07-cap-d...WS4/Velkushanova.pdf

This looks really interesting, but it wasn't clear to me what the timeline for developing these standard operating procedures are? When do you plan to heave them ready by? Once they are ready, how will they be made available to everyone? Will there be some sort of peer-review process for them or a testing scheme amongst different laboratories to see if they really work well?




About your new grant, congratulations on that one! I see it's another big one (1.6 million USD):
www.gatesfoundation.org/How-We-Work/Quic...s/2014/11/OPP1119939

I suggest we start a separate thread for it so that full details of the grant, and then progress over the next two years can easily be followed on the forum. I will e-mail you about that. Thanks.

Regards,
Elisabeth]]>

The three FSM3 presentations of Chris Buckley and myself are available now at www.susana.org/en/resources/library/details/1707 (Files 18, 19 and 20 in the list)

We received good feedback and are happy to announce that our list of collaborators is continuously increasing.

My presentation is also related to another BMGF project - "Mechanical Properties of Faecal Sludge" which was finalized last year. You can access a paper under this project that has been accepted for publication and is currently being corrected from here
. Additional data is available on request.

The "Data acquisition and field support for sanitation projects" is nearly completed, too. Some of the progress reports and the major findings from all Masters students will be posted soon.

At the end of last year we signed another grant agreement with BMGF with the title: "EQUIPMENT AND HEALTH AND SAFETY MODIFICATIONS REQUIRED FOR DEVELOPING THE CAPACITY TO SUPPORT GRANTEES FIELD TESTING IN DURBAN, SA". The agreement is valid until 31 October 2017 and is with the charitable purpose "To augment the services provided with transformative technology grantees and sanitation practitioners wishing to demonstrate their technologies in Eastern Africa".

Thanks again for your insightful question. We're still not concerned about biofouling due to the membrane materials. But we are a bit concerned about the formation of salt crystals on the membrane surface - these would be derived predominantly from urine. So this is what one of our post docs, Olivier Autin, is looking at.

I hope this clarifies this and if you have any other questions then Olivier and I can try to answer them!

However, I see that there are biofouling experts on the project team.

I'm sorry if the posts above are not clear. The membrane is still a core part of the toilet, allowing us to dewater the waste for combustion and produce clean water. The membrane relies on nano scale processes for its operation.

I hope this is clearer but if there's anything else just post here or drop me an e-mail!

The RTTC technologies listed in the presentation are used as potential examples and are not confirmed for demonstration. Nor will SASTEP technologies be limited to the technologies considered in the presentation.

Development and field-testing of an onsite, self-contained and sun-powered human and toilet wastewater treatment system: Michael Hoffmann, Linde-Robinson Laboratories, California Institute of Technology, Pasadena, Cal, USA
www.susana.org/images/documents/07-cap-d.../3-3-4-1Hoffmann.pdf

The presentation contains a lot of slides with photos, so it will be good to have the video of the presentation available as well (soon I hope - waiting for Tjibbe to send the files to the SuSanA secretariat).

Here one slide from the presentation to wet your appetite to view the presentation:



From my scribbled notes:
  • The projet start in mid 2011
  • Solar power is stored in batteries
  • There is now a collaboration with the company Kohler - to commercialise this
  • Test ongoing at an elementary school in China (see photos)
  • Membrane bioreactor (MBR) to process collected waste (folded plate anaerobic digester)
  • Electrochemical system, oxidise the effluent with chloride - electrode reactor, semi-conductor electrodes
  • 100 students use the toilet, only about 10 use it for defecation on a typical day, i.e. contribution of faeces is quite low
  • One prototype in Kerala (India) at a university
  • No discharge of water
  • Anal washing spray provided
  • Grinding of solids in the wastewater
  • Replacement of batteries needed from time to time
  • Aiming for 15,000 USD per complete unit, or around 5,000 USD for a simpler version
  • Hydroxy appatite and calcium accumulates but no struvite precipitation

This technology has also been selected by BMGF for further larger-scale field tests and possibly upscaling.
For example, it will also be tested in South Africa as far as I know, see this thread:
forum.susana.org/forum/categories/139-gr...st-partnership#10930

And as far as I know further prototypes (up to 100 if I remember correctly? Will need to check this) will be tested in India.

I don't think this will be a solution for the urban poor, but perhaps for the urban middle-class or specialised applications, such as schools and maybe high-rise buildings with little space and not connected to the sewer. Will be interesting to see how it all pans out.

Elisabeth]]>

We are building on all the exciting progress we made in Phase 2 to make a smaller, more efficient, and cheaper version of our prototype. The technology will not differ much from our Phase 2 prototype. For a very excellent summary of our technology please watch our animated video.
