Gross-Wen Technologies awarded $240,000 grant to develop phosphorus removal technology

Slater-based Gross-Wen Technologies (GWT) has received a $240,000 grant from the Department of Energy to develop a next-generation process to remove phosphorus from wastewater.

For the project, GWT will work with the Metropolitan Water Reclamation District of Greater Chicago to develop a next-generation algal wastewater treatment process to improve phosphorus removal from wastewater.

The research will use specific strains of algae to be developed at the Renewable Energy Laboratory and a modified version of Gross-Wen’s patented algal wastewater treatment technology which removes nitrogen, phosphorus, and other pollutants from municipal wastewater.

“Our project addresses a critical efficiency issue in wastewater treatment,” Martin Gross, founder and CEO of GWT, said in an announcement. “Wastewater treatment facilities around the country are facing increasingly stringent nutrient discharge limits, especially with regard to phosphorus removal, and are looking for new technologies to meet these new permits. We aim to develop strategies to maximize our algal-based wastewater treatment system’s efficiencies in order to achieve a significant overall nutrient removal outcome and minimized system footprint.”

GWT’s patented technology is based on research developed at Iowa State University. GWT is a member of the Iowa State University Startup Factory’s inaugural cohort and is an AgStartup Engine portfolio company.
