Re: The Nano Membrane Toilet (Cranfield University, UK) - latest results and publications since 2016

We've had a few publications from the Nano Membrane Toilet team recently but I think this one will be particularly interesting to the SuSanA audience:

Field testing of a prototype mechanical toilet flush

The Nano Membrane Toilet needs a waterless flush to reduce the amount of liquid that needs to be processed subsequently. A prototype was tested in a semi-public, institutional setting and in selected peri-urban households in eThekwini municipality, Republic of South Africa. The mechanism's functionality and users' perception of the flush were assessed. User perception varied depending on background: Users accustomed to porcelain water flush toilets were open to, yet reserved about the idea of using a waterless flush in their homes. Those who commonly use Urine Diversion Dehydration Toilets were far more receptive. The user-centred field trials were complemented by a controlled laboratory experiment, using synthetic urine, faeces, and menstrual blood, to systematically assess the efficiency of three swipe materials to clean the rotating bowl of the flush. A silicone rubber with oil-bleed-effect was found to be the best performing material for the swipe. Lubrication of the bowl prior to use further reduced fouling.
