Gross-Wen Technologies (GWT) uses its patented wastewater treatment technology, known as the revolving algal biofilm system (RAB), to cost-effectively recover nutrients such as nitrogen and phosphorus from wastewater. Compared to other treatment options, GWT's system is significantly more affordable and produces algae biomass which can be sold as a slow release algal fertilizer or bioplastic.
