Key Takeaways
- Gross-Wen Technologies (GWT) has signed a commercial partnership agreement with Xylem, a global water technology company, to jointly deploy integrated wastewater treatment solutions for industrial facilities.
- The agreement combines Xylem's anaerobic treatment platform with GWT's patented Revolving Algal Biofilm™ (RAB™) technology to deliver nutrient removal and organic loading compliance in a single integrated offering.
- Both technologies were independently deployed at a major industrial wastewater project in Pasco, Washington, where their field compatibility and complementary capabilities were first demonstrated.
- The partnership targets industrial facilities facing tightening nutrient discharge regulations, with anaerobic digestion operations identified as a key focus market.
- The agreement is expected to accelerate GWT's expansion into the industrial wastewater sector while giving customers a more streamlined path to wastewater compliance.
Gross-Wen Technologies Partners with Xylem to Deploy Integrated Industrial Wastewater Solutions
Gross-Wen Technologies (GWT), a developer of algae-based wastewater treatment systems, has announced a commercial partnership with water technology company Xylem. The agreement is designed to accelerate GWT's expansion into the industrial wastewater sector by pairing its Revolving Algal Biofilm™ (RAB™) nutrient removal technology with Xylem's established anaerobic treatment platform, creating a more complete compliance solution for industrial operators.
The deal targets industrial facilities — particularly those operating anaerobic digestion processes — where tightening nutrient discharge regulations and broader sustainability requirements are driving demand for integrated treatment approaches that address both organic loading and nutrient removal in a single deployment.
A Partnership Validated by the Pasco, Washington Project
The commercial agreement is grounded in demonstrated field performance. Both GWT and Xylem were independently selected for an industrial wastewater project in Pasco, Washington, where their respective systems were deployed together to meet the state's stringent nutrient discharge standards. Without a formal partnership at the time, the project showed how the two technologies — Xylem's anaerobic platform and GWT's RAB™ nutrient removal system — work together effectively, creating a template for future integrated deployments.
“This partnership is a transformational step for Gross-Wen Technologies. By combining our nutrient removal technology with Xylem's industry-leading wastewater treatment solutions, we can help industrial facilities meet evolving water quality and sustainability goals. We are excited about what we can accomplish together as we bring new solutions to a rapidly changing water market,” said Martin Gross, Founder and CEO of GWT.
“We saw firsthand through the Pasco project how our technology and GWT's nutrient removal platform complement each other. By formalizing our partnership, we can streamline delivery of integrated solutions and better serve industrial customers seeking reliable, compliant, and sustainable wastewater treatment options,” said Bob Wenta, Senior Director Customer Verticals at Xylem.
GWT RAB™ Technology and the Wastewater Nutrient Challenge
GWT's Revolving Algal Biofilm™ system uses algae grown on a rotating surface to capture and remove nitrogen and phosphorus from wastewater — nutrients that are increasingly regulated across industrial and municipal discharge frameworks. When paired with anaerobic digestion effluent, which is typically high in nutrient load, the RAB™ system addresses a treatment gap that conventional biological processes often struggle to fill cost-effectively. The Xylem partnership provides GWT with commercial infrastructure and established customer relationships to scale this approach into new US industrial markets.
