PFAS Removal
ProSelect PFAS can be used for removal of various PFAS compounds, including PFOA and PFOS, from water. Currently, this is a non-regnerable application. Testing has shown it can remove a wide range of other PFAS species in addition to these compounds. Ion exchange offers the benefit of reduced contact times and longer throughputs vs. conventional activated carbon treatment. An understanding of the influent water chemistry is needed for thorough review. Levels of TOC, VOC, and individual PFAS compounds are needed in addition to the basic background water chemistry (chloride, sulfate, alkalinity, etc.). Any other contaminants that may be present are also needed to determine impact on PFAS removal (uranium, perchlorate, chromate, arsenic, etc.). |

Perchlorate Removal
ProSelect PFAS is ideal for single use perchlorate removal applications and is a cost effective method to remove trace levels of perchlorate from water. The perchlorate ion is very strongly attracted to ProSelect PFAS—so much so that regeneration is impractical or impossible. However, in most cases, ER20012-MP loads perchlorate to almost the full capacity of the resin, resulting in very long life and eliminating the need to regenerate and re-use the spent resin. |
