OriginOil debuts “attached growth” algae production system for wastewater treatment; low dewatering cost a feature

In California, OriginOil announced a production system using a type of algae that attaches itself to growth surfaces. The new system helps pursue clean water goals while generating algae for fuel and other valuable products in wastewater treatment plants. The company recently filed for patent protection of the new Attached Growth System, its ninth patent application, entitled “Methods and Apparatus for Growing Algae on a Solid Surface.”

OriginOil will integrate the process into the demonstration algae system now being built at its headquarters. OriginOil’s Attached Growth System uses types of algae that will attach to surfaces rotating in and out of the water, exposing the algae to sunlight or artificial light. At harvest time, the algae is scraped off as a sludge, greatly decreasing the energy cost of dewatering during oil extraction.
