In developing a nitrogen and phosphorous removal system using algae, the inventors and researchers also identified that it could remove total dissolved solids (TDS). The revolving algae biofilm (RAB) technology developed by Gross-Wen Technologies is now patented.
Martin Gross, CEO of Gross-Wen Technologies, explains how RAB works, the scales at which it has been tested, how it came to be and where the technology is headed next.
Gross-Wen Technologies along with the Metropolitan Water Reclamation District of Greater Chicago announced a patent for the removal of total dissolved solids in wastewater.
