WSP has developed a uniquely effective solution for rapid, on-site elimination of per- and polyfluoroalkyl substances (PFAS) along with other persistent water contaminants: an electro-oxidation wastewater treatment system known as PFASER. The water treatment unit (patent pending) exclusively incorporates pro aqua’s best-in-class commercial boron-doped diamond (BDD) electrode reactors, giving it a competitive edge for efficiency, longevity and operational costs.
A durable, modular and cost-effective solution
PFASER is grounded in WSP’s longstanding leadership in addressing the impacts of PFAS, and the development of an electro-oxidation process with BDD electrodes by WSP’s Senior Water Treatment Engineer Dr. Valérie Léveillé. Over several years of research and development that included extensive lab testing and two pilot projects, WSP’s scientists confirmed pro aqua’s BDD electrodes as a superior choice for PFAS destruction. Pairing efficiency and longevity, these electrodes have already proven their ability to operate continuously for over six years and are expected to last many more.
PFASER also includes another competitive advantage: it is the first commercially available water treatment unit that also removes perchlorate, an unwelcome byproduct of the electro-oxidation process. WSP’s proprietary perchlorate removal process, in combination with pro aqua’s electrodes, ensures effluents meet stringent international standards for drinking water or discharge into city sewers or the environment.
“Thanks to our deep expertise in electro-oxidation for water treatment and our synergistic partnership with pro aqua, we can now offer our clients an industry-leading, durable, modular and scalable solution that helps them meet even the most stringent regulatory requirements for on-site elimination of water contaminants,” said André-Martin Bouchard, Global Director, Earth & Environment, WSP. “By setting a new benchmark for water quality and safety worldwide, we are also unlocking new commercial opportunities in water-related services—a key high-growth area in our current strategic cycle.”
