Algae Treatment Technology

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.

Better Cost Compared to Traditional Options

Not only does Gross-Wen Technologies supply a superior water treatment solution in terms of environmental impact, but our process is also a less expensive one. We’re happy to provide municipalities and wastewater-producing industries an alternative to the bacterial and chemical treatment systems commonly on the market today.
