Gross-Wen Technologies products

Gross-Wen Technologies uses its patented wastewater treatment technology, known as the revolving algal biofilm system (RAB), to cost-effectively address new wastewater permits that are being required at municipalities and industries. The RAB system uses vertically oriented conveyor belts that grow algae on their surface. While the algae grows it “eats” nitrogen and phosphorus from the wastewater. It also uses Carbon Dioxide from the atmosphere and sunlight to rapidly grow algae biomass. The algae produced during this process is a revenue stream for our customers and can be used to make fertilizers, bioplastics and biofuels.
