Design and Operation Guidelines for PFAS Removal

This guide provides detailed design and operational guidelines for water systems utilizing Purofine PFA694E PFAS-selective single-use ion exchange resin aimed at removing per- and polyfluoroalkyl substances (PFAS) from drinking water. The document outlines critical considerations for system design, including pretreatment requirements to prevent fouling, such as the removal of total suspended solids, oil, grease, and dissolved metals like iron and manganese. It emphasizes the importance of maintaining optimal conditions to ensure the longevity and effectiveness of the resin. The guide also discusses the design of resin vessels, including bed depth, flow rates, and the need for proper influent distribution to avoid channeling. Additionally, it recommends configurations such as lead-lag systems to enhance operational efficiency and reduce costs. Operational considerations, troubleshooting tips, and references for further information are included to assist operators in achieving effective PFAS removal.
