Guidelines for PFAS Removal Using Purofine PFA694

This guide provides detailed design and operational guidelines for water systems utilizing Purofine PFA694, a PFAS-selective single-use ion exchange resin aimed at removing per- and polyfluoroalkyl substances (PFAS) from water and wastewater. It outlines the importance of proper system design and operation to achieve effective PFAS reduction to non-detectable levels. Key sections include pretreatment requirements, resin vessel design, and operational considerations. The guide emphasizes the critical role of prefiltration in preventing resin fouling and discusses the impact of total dissolved solids, oil, grease, and other contaminants on resin performance. Recommendations for optimizing resin use, including configuration strategies like lead-lag setups, are presented to enhance efficiency and reduce operational costs. The document also addresses potential issues such as scaling and microbial contamination, providing actionable recommendations for system maintenance and troubleshooting. Overall, it serves as a comprehensive resource for operators seeking to implement effective PFAS treatment solutions.
