Aquagga Launches First Municipal-Scale PFAS Destruction Demonstration in Tacoma, WA

February 19, 2025

In January, Aquagga brought their Steed series system onsite at the Tacoma Central Wastewater Treatment Plant (WWTP) to begin a new PFAS destruction demonstration project with the City of Tacoma, in partnership with the Washington State Department of Ecology and the University of Washington-Tacoma.

This two-phase project will showcase the potential for municipal-scale PFAS solutions, starting with PFAS separation and concentration using foam fractionation technology from ECT2, followed by complete PFAS destruction with Aquagga’s Steed Series system.

HALT Demonstration Day: A Community Celebration

To celebrate this milestone project, Aquagga hosted an event at the Tacoma Central WWTP on January 31, bringing together key community members, stakeholders, and supporters. During the event, the Aquagga team hosted a Welcome Reception where CEO, Dhileep Sivam presented about the project, followed by an onsite tour of ECT2’s foam fractionation technology and Aquagga’s HALT technology. Attendees had the unique opportunity to witness HALT technology onsite before the PFAS destruction phase commenced.

The event served as a platform for fostering connections and sharing insights into the project’s impact. “We’ve had so much support from the Tacoma community, and we were excited to showcase our work here at home after so many deployments elsewhere in the country,” said Dhileep Sivam, CEO of Aquagga. “Our technology can transform how municipalities tackle PFAS challenges, and we’re proud that our friends and neighbors could see it in action.”

Addressing Municipal PFAS Challenges

This project marks Aquagga’s first municipal-scale demonstration, building on a series of successful deployments across the country. It highlights the feasibility of pairing foam fractionation with HALT to efficiently remove and destroy PFAS in municipal wastewater.

The purpose of this PFAS destruction pilot demonstration in Tacoma is to address wastewater challenges and demonstrate the technology is ready for broader adoption in municipal and industrial applications. By refining and showcasing this approach, Aquagga is helping to lead the charge in providing scalable, sustainable solutions for one of the world’s toughest water contaminants.
