Gross-Wen Technologies builds algae-based wastewater treatment systems for municipal and industrial customers. It serves utilities and industrial water managers replacing chemical-intensive phosphorus and nitrogen removal. Its Revolving Algal Biofilm system uses algae instead of chemicals for nutrient removal, generating biomass byproducts most chemical-based competitors throw away.
