OriginOil feeds its algae using the cleaned sewage water
OriginOil has developed a process to treat liquid sewage at the point of origin and use it to feed and grow algae for fuel. A prototype of the system, known as the Electro Water Separation system, is now installed at an urban algae demonstration site near Paris. Human sewage is first separated into solids and liquids using Ennesys’s (Ennesys is one of OriginOil’s joint ventures ) technology. OriginOil’s EWS Waste process then sanitizes the fluids and converts the urea into nitrates. The clean, fertile water is then fed into the algae tubes on the roof of the building, where algae grows and is harvested daily for energy.
