riginOil, Inc.’s Electro Water Separation™ system (EWS) has just been successfully demonstrated to treat liquid sewage directly in commercial buildings. A prototype EWS Waste unit (the Waste Appliance™) now processes liquid waste at an urban algae demonstration site in an office building near Paris, France – generating clean, nitrate-rich water to feed algae grown on the building’s roof as an energy source.
“By utilizing human waste as a feedstock for algae energy, we are showing that urban algae production can meet many essential building requirements, energy generation and waste disposal alike, in a simple closed loop system,” said Jean-Louis Kindler, CTO of Paris-based Ennesys, OriginOil’s joint venture partner.
In the Ennesys system, human sewage is first separated into solids and liquids. 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.
The demonstration unit is reportedly able to process about 250,000 liters per day, with more efficiency gains expected. “It may come as a surprise to many that it is actually just as easy to clean building sewage as it is to treat fish farm water,” said Nicholas Eckelberry, OriginOil co-founder and chief inventor. “What we learned in the Salton Sea area of California directly helped us succeed in France.”
Located in the iconic La Défense complex near Paris, the permanent Ennesys showcase is demonstrating that algae can help commercial buildings cleanly generate more energy than they consume, and to purify their wastewater, as envisioned by France’s ambitious RT 2020 sustainable energy framework.
