FluidynoSan Aero-Anaerobic Toilets

Next-generation sanitation technology for remote and unserved areas of Africa. The FluidynoSan Aero-Anaerobic Toilet is a self-sustaining, solar-powered, waterborne flush toilet that treats raw sewage on site through a unique combined aerobic/anaerobic biological process — converting waste into re-usable filtered grey water with no connection to municipal water or sewer. A proprietary Bacillus bacteria blend drives biological breakdown in the digester, while a solar-powered recycle pump (12V, 2000 l/h, 3.2 m head) and inline activated-carbon filter complete the cycle. The double-walled rotomoulded LLDPE hut doubles as a cistern supply tank and harvests rainwater from its roof. One unit comfortably serves five households (~25 people) or up to 50 children at a crèche, reducing household water consumption by up to 70% (19,440 L → 300 L per 90 days) and eliminating the risk of groundwater contamination. Endorsed by the Gates Foundation, FluidynoSan has been installed across South Africa, Namibia, Botswana, Nigeria, Ghana, and Tanzania — with interest from Senegal, Southern Sudan, Angola, Zimbabwe, Mozambique, India, and Bangladesh. Reference installations include CSIR Pretoria, Syferfontein informal settlement in George, Machaka Traditional Council Offices in Limpopo, and Siyafunda Crèche in Knysna, where the unit serves 85 children and staff.
