StreamGo, a provider of advanced water and wastewater treatment systems, announced the appointment of industry veteran Steve Watzeck as CEO and the launch of the first integrated system using nanobubbles to capture, concentrate and destroy PFAS. The system is powered by two new technologies: NanoFoam™, which uses the nanobubbles to capture and concentrate long- and short-chain PFAS, and EndStream™, which destroys the concentrated stream. The approach is designed to deliver broad spectrum PFAS capture and destruction with a smaller footprint, lower energy use, and zero harmful byproducts.
PFAS, commonly known as 鈥渇orever chemicals,鈥� have become a growing challenge for communities and industries nationally and globally. A U.S. Geological Survey study estimated that at least 45% of U.S. tap water could contain one or more types of PFAS. In May, EPA announced nearly $1 billion in funding to help communities address the issue. A 2025 international study confirmed PFAS contamination in tap water across 21 countries.
鈥淪treamGo has invested years developing, demonstrating and validating proprietary technologies for some of the most difficult challenges including emerging contaminants and reuse in water treatment,鈥� said Watzeck, who is also a member of the board. 鈥淲e have the engineering expertise and treatment capabilities to address the most complex waste streams including broad spectrum PFAS from beginning to end 鈥� and we鈥檙e ready to commercially scale across verticals from municipal to military.鈥�
Watzeck brings more than 30 years of global water and wastewater industry experience, with a track record of scaling technologies and businesses across startups, mid-sized and global enterprises. Most recently, as CEO of Fibracast, he led the launch and expansion of its multi-generation FibrePlate membrane technology across North America, Europe and Asia. Previously, he served as CEO of Anaergia and held senior leadership roles at GE Water & Process Technologies, where he led the integration of Zenon Environmental and three other acquisitions into a global engineered water solutions platform. Earlier, as president and senior vice president of Zenon, he was instrumental in scaling up the company鈥檚 ZeeWeed membrane technology globally.
Conventional treatment solutions typically remove PFAS from water but can leave the compounds in spent media, resins, or other residual waste streams that require further treatment or disposal. StreamGo鈥檚 integrated PFAS Capture, Concentrate, and Destroy system addresses the process from initial separation through destruction:
-
Capture: Conventional foam fractionation typically uses microbubbles to separate mainly long-chain PFAS from water. NanoFoam™ uses much smaller nanobubbles, creating more surface area for accumulation. The nanobubbles also enable capture of both long- and short-chain PFAS, including smaller, more mobile compounds conventional approaches often struggle to remove.
-
Concentrate: NanoFoam™ also concentrates the captured PFAS into a small residual stream, reducing the volume that must move to the destruction stage by 1000x. That reduces the energy and cost required for destruction.
-
Destroy: EndStreamTM combines a proprietary enhanced photochemical reduction process to destroy concentrated PFAS, rather than leaving a PFAS-containing waste stream that requires disposal.
鈥淯sing our proprietary nanobubbles in combination with the microbubbles typically used in foam fractionation allows us to capture short as well as long-chain PFAS with a smaller footprint and lower energy use,鈥� said Richard Nie, Founder, President, and CTO of StreamGo. 鈥淭hen we take it a step further by integrating capture and destruction in one automated system. We鈥檙e giving customers a total solution to address PFAS rather than simply moving the problem somewhere else.鈥�
