Our Approach to Clean Water

Gross-Wen Technologies uses its patent pending wastewater treatment technology, known as the revolving algal biofilm system (RAB), to cost effectively address the new ammonia permits that are being enforced at municipalities using lagoon treatment. Our system uses algae to recover nutrients such as nitrogen and phosphorus from wastewater. Compared to other ammonia treatment options our system is fraction of the cost and produces algae biomass which can be sold as a slow release algal fertilizer. Overall the process is carbon negative, making it the most sustainable approach to treat nitrogen and phosphorus from wastewater. Our algae system can be used by larger municipalities and industries to treat nutrients, CBOD and toxic metals as well.
