Re: The Nano Membrane Toilet - by: AParker
Thanks for your interest in the Nano Membrane Toilet. It's not actually so different, really the main thing is the addition of the gasifier and pelletiser.

The ash will be disposed of with the household solid waste - and of course there will be a way of releasing it form the gasifier. The design is still under development so this is just representative!

You're welcome to use the text on the front page of our website for your article:

Re: The Nano Membrane Toilet - by: mwaniki
Thanks for publishing the modified diagram of the nano membrane toilet. This version is very different from the one that was reported in the Africa Water, Sanitation & Hygiene Jan – Feb 2016 edition.

However, am curious to ask what happens to the ash after the waste is turned into energy in the gasifier. I can’t see any release screw underneath the chamber.

And if you could kindly let us have the accompanying text (maybe 200 words or thereabout), we could reprint it in the oncoming edition of the above publication for the benefit of our audience.

Re: Safe sludge – The disinfection of latrine faecal sludge with ammonia naturally present in excreta (University of California, Berkeley, USA) - by: muench
Here are the details:

In-toilet disinfection of fresh fecal sludge with ammonia naturally present in excreta

Temitope A. Ogunyoku, Fikreselam Habebo, Kara L. Nelson
Published March 2016, 6 (1) 104-114; DOI: 10.2166/washdev.2015.233


A simple treatment method, Safe Sludge disinfection, was developed to disinfect pathogens in fresh fecal sludge using the ammonia naturally present in excreta. In the first step, urea is hydrolyzed to ammonia (NH3/NH4+). In the second step, Ca(OH)2 is added to raise the pH level such that NH3, a known disinfectant, is the dominant form of ammonia; subsequently, the waste is stored until sufficient disinfection is achieved. In a closed system at 23 °C, Safe Sludge disinfection achieved >9.3 log10 and >4.0 log10 decrease of indigenous Escherichia coli and seeded MS2 coliphage, respectively, within 10.6 hours, and 2.0 log10 inactivation of seeded Ascaris suum eggs within 2 weeks.

Disinfection of feces at high pH with no urine addition was tested for comparison, and similar inactivation levels were achieved for E. coli and MS2 bacteriophage. However, for Ascaris eggs only 0.38 log10 inactivation was achieved over 2 weeks. For control samples (feces plus urine only), no inactivation of bacteria or virus indicators was observed and inactivation of Ascaris eggs was also low (0.42 log10). To illustrate how the Safe Sludge concept could be incorporated into a waterless household toilet, a conceptual design and prototype was developed, called the pHree Loo.


P.S. I noticed that the question by Patty from 2 years ago haven't been answered yet. I will try to alert the people from the project to them, perhaps they could still answer them.]]>

Title of grant: Equipment and health and safety modifications required for developing the capacity to support grantees field-testing in Durban, SA

Name of lead organization: University of KwaZulu-Natal
Primary contact at lead organization: Chris Buckley
Grantee location: Durban, South Africa
Countries where the project takes place: South Africa, Senegal, East Africa and India
Start and end date: 10 Nov. 2014 to 31 Oct. 2017
Grant type: Other (supporting researchers from the Reinvent the Toilet Challenge scheme, but also other researchers)
Grant size: USD 1,600,432 (as per BMGF grant database here)

Short description of the project:

The grant was awarded to the Pollution Research Group (PRG) at the University of KwaZulu-Natal in order to increase the capacity of the PRG to provide support to sanitation practitioners working in the faecal sludge management field. This included covering the cost of upgrading the laboratory to increase health and safety (improved extraction, storage etc.), provide more space for visiting researchers, and to purchase analytical equipment to increase the range of tests that can be undertaken.

In addition, the PRG offers training support to other laboratories wishing to undertake similar analyses. Staff labour costs of the PRG are covered by the grant, but all other costs such as chemicals, consumables, and travel and subsistence need to be covered by the researcher requesting assistance. Application for support can be made to Chris Buckley via email ( This e-mail address is being protected from spambots. You need JavaScript enabled to view it ).

  • To augment the services provided to transformative technology grantees and sanitation practitioners wishing to demonstrate their technologies in Eastern Africa
  • To provide laboratory and testing services to SteP (Sanitation Technology Evaluation Programme) in which prototypes developed by the Reinvent the Toilet Challenge and other initiatives are operated in a realistic environment (Senegal, Durban and Coimbatore)
  • To provide laboratory, and field testing support services to faecal sludge researchers

  • To have a laboratory, field testing and office facilities available for use by faecal sludge researchers
  • Increase the chemical, physical and microbiological data available of relevance to faecal sludge researchers

Grant update: Viscous Heating for Helminth Deactivation in Fecal Sludge - by: garyfoutchosu
Title of grant: Viscous Heating for Helminth Deactivation in Fecal Sludge (200 to 1000 Liters/Hour)
Subtitle: Scale-up of viscous heater technology
Name of lead organization: University of Missouri – Kansas City
Primary contact at lead organization: Gary L Foutch
Grantee location: Kansas City, Missouri
Country where the research is being tested: At UKZN in Durban, South Africa
Start and end date: January to December 2016
Grant type: Initially we were a GCE, now funded by Water, Sanitation and Hygiene, Global Development
Grant size: USD 336,733 (as per BMGF grant database here)

Short description of the project:

We were successful in destroying Helminth eggs, particularly Ascaris lumbricoides, in VIP sludge during Phase 2 using viscous heating. Our next step is to scale-up the equipment for larger flow rates. This year we will design, build and test equipment that can operate effectively at 200 and 1000 L/hr. Our computational fluid dynamics design is underway with construction of devices beginning in May and testing in Durban during late summer and fall. Viscous heating allows any viscous fluid to heat itself on the molecular level by passing it through a shear field. No additional heating is required, we have achieved experimental temperatures up to 190 C. For Ascaris, no eggs have survived 80 C effluent temperatures. Water addition is not desired.

Goal(s): Prove that viscous heating can work at scale.

It may seem a bit "high tech" (this is also my first reaction) but let's keep in mind that this is for the Chinese market, and perhaps not necessarily for very poor people. Mind you, the project description also mentions African countries so I'd be curious to know which African countries and which segment of society these innovations are geared towards?

Regarding high tech devices, a mobile phone is also high tech and yet it has become a cherished possession for so many poor households. How come? I guess it's because it requires no maintenance by the user, except for charging it, and it provides such an excellent service (communication, banking, access to information) that people won't forget to charge their mobile phones regularly. Users never have to look at the inside of their mobile phone, so it doesn't matter how complex it is inside.

Whether something equivalent could ever be achieved for a novel toilet + sanitation system, I don't know. But if it did, it would be fabolous!

It would be nice to find out more about these Chinese research projects, if possible.

Waterless Toilet that Turns Fecal Matter into Clean Water and Power - by: F H Mughal Waterless Toilet that Turns Fecal Matter into Clean Water and Power

Cranfield University, UK has designed a toilet turns human waste into electricity and clean water. It has been called as the Nano Membrane Toilet. Cranfield University says that this new approach to managing waste could help some of the world's 2.3 billion people who have no access to safe, hygienic toilets.

How does the toilet works? The post says:

The toilet's magic happens when you close the lid. The bottom of the bowl uses a rotation mechanism to sweep the waste into a sedimentation chamber, which helps block any odors from escaping. The waste is then filtered through a special nanotech membrane, which separates vaporized water molecules from the rest of the waste, helping to prevent pathogens and solids from being carried further by the water.

The vaporized water then travels through to a chamber filled with "nano-coated hydrophilic beads", which helps the water vapor condense and fall into a collection area below. This water is pure enough to be used for household washing and farm irrigation.

The residual solid waste and pathogens are driven by an archimedean screw into a second chamber. This part of the design is still being finalized, but the current plan is for the solid waste to be incinerated to convert it into ash and energy. The energy will power the nanomembrane filtration process, with enough left over to charge mobile phones or other small devices.

The above link gives a video on how the toilet works.

While it is a great innovation, one would doubt, where its applicability would be compatible with the scenarios in poor developing countries. The proposed toilet appears more appropriate for developed countries, and for the large hotels and yachts. It will be difficult to say whether it would be helpful to large populations in poor developing countries, which lack improved sanitation.

Re: The Nano Membrane Toilet (Cranfield University, UK) - new phase of funding until Jan. 2016 - by: AParker
Yes it's been a pretty crazy couple of weeks for the project! Lots of media coverage, some exaggeration, and the usual mix of criticism and enthusiasm!

Actually as Elisabeth points out we don't have any updates to share yet while we finalize the IP protection. Of course our blog will be the first place we share updates:

And the SuSanA forum will be the second!

The webinar I referred to in my e-mail was part of the grantee webinar programme, so I'm not sure it's my place to share the link to the recording or introduce the STeP programme. Elisabeth - maybe this is something you could follow up?

Happy to answer any other questions in the meantime, but be assured we will have a lot more to share soon!

Re: The Nano Membrane Toilet (Cranfield University, UK) - new phase of funding until Jan. 2016 - by: muench
Even Bill Gates mentioned it on his Facebook website (always good to see Bill talk about toilets - whichever toilets they are):

Here is the link to the post on the "I fucking love Science" Facebook page which he had shared (sorry for the rude language but that is the name of that particular Facebook account; they also have a good twitter handle by the way):

It got 1400 comments so far! I had a look at the first few, it seems to be the usual mixture of "toilet humor" jokes to "do we really need this?" to "this looks far too complicated for developing countries" to "I want to buy one!".

I asked Alison on Twitter if she could post an update and this is here reply on twitter:

Alison Parker ‏@AlisonP_WASH 6. Jan.
@EvMuench @saniblog Hi Elisabeth we're making progress with the IP protection so should be able to share more soon!

@EvMuench @saniblog also media reports that we're "about to trial in Ghana" are much exaggerated - it will still be a few months yet!

Here's another link to an article about the toilet in mainstream media:

Anyhow, it's funny how the media picks up on a story and then it gets repeated in different places.

This thing about IP protection is something we've talked about on the forum quite a bit. It seems counter-intuitive at first but Alison explained to me:
Have you been following the STEP programme? They talked a lot about protecting IP in the introductory webinar. They talked to a lot of potential commercialisation partners and realised that few of them would be keen to engage without protected IP.

Interesting point!
Alison, I hope you don't mind that I took that quote from your e-mail to me - but I think it raises a good point. Would you be able to provide the link to the mentioned webinar? Sounds very interesting.
