Effective & Sustainable PFAS Removal with ECT2 SORBIXTM Technology
Keith Foster and Camille White
ECT2 San Diego
Per- and polyfluoro-alkyl substances (PFAS) have historically been used in a broad range of consumer and commercial products and in the manufacturing of aqueous film-forming foams (AFFF). Due to their water solubility, PFAS, unlike many other persistent organic chemicals, end up in ground and surface waters and can require treatment. In 2016, The Environmental Protection Agency (EPA) established a Health Advisory Level (HAL) of 70 parts per trillion (ppt) for PFOA and PFOS, which are two commonly produced PFAS chemicals. In June 2019, The California Water Board released a Notification Level for PFOA and PFOS at concentrations of 14 ppt and 13 ppt, respectively.
Due to their unique chemical structure and properties, commonly used water treatment options such as biological treatment, air stripping and advanced oxidation do not adequately treat for PFAS compounds. Treatment techniques that will successfully remove PFAS compounds are Granular Activated Carbon (GAC), foam fractionation, reverse osmosis and ion exchange resin. Based on performance, cost effectiveness, and overall equipment footprint, Emerging Compounds Treatment Technologies (ECT2) uses Ion Exchange Resin technology (SORBIX) for PFAS remediation systems. The superior performance is realized by a dual mechanism of removal afforded by traditional adsorption on the styrene-divinyl benzene backbone of the resin and ion exchange at functionalized ion exchange sites. ECT2 has developed proprietary ion exchange resin regeneration techniques that allow for the ion exchange resin to be re-used. Such processes result in dramatic reductions in waste generation. ECT2 offers a variety of systems ranging from whole house point of entry treatment, to drinking water treatment plants, to construction site dewatering systems. ECT2 offers single use and regenerable systems to create highly adaptable, flexible designs for varying site needs.
ECT2 has successfully implemented full-scale PFAS removal systems around the world. The Royal Australian Air Force (RAAF) Base in Williamtown, NSW AU houses three full-scale regenerable SORBIX systems with one centralized regeneration facility. By April 2019, over 382 million litres of water had been treated on site, removing eight kilograms (kgs) of PFAS and generating less than 3,600 kgs of total waste, including the waste generated by the pretreatment systems. All three treatment systems have consistently met the project objectives, including compliance with Australia’s health-based guidance values (HBGVs) and other PFAS removal goals.
ECT2 is also working on providing solutions for high concentration PFAS applications (emergency releases, infrastructure decommissioning projects, etc.) as well as partnering with academic leaders in developing PFAS destruction techniques
Keith Foster - Experienced water treatment professional with a focus in applications engineering and full-scale operations and analysis. Responsible for assisting with concept-level design and process equipment sizing, developing and maintaining kinetic models, conceptual system costing, and preliminary equipment selection of innovative water and air treatment systems. He graduated with a Bachelor’s focused in Geology & Geochemistry from the University of California, Berkeley.
Camille White is a Design Engineer at ECT2 who has always had a passion for the water resources market sector. She joined ECT2 at the end of 2018 and has aided in the design of many full-scale PFAS removal water treatment systems, including their new SORBIXTM Pure product line. Camille is responsible for engineering calculations, drawings, vendor communications and optimizing ECT2’s highly technical products. She holds a Bachelor of Science degree in Environmental Engineering from Northern Arizona University.
