Strong Base Anion PFAS Resin

ResinTech SIR-110-HP is a chloride-form, gel strong-base anion resin engineered for the selective removal of perchlorate, nitrate, and most PFAS compounds from drinking water. The "HP" designation signals that it is Gold Seal Certified by the WQA for use in potable water applications—an important assurance for any system treating water intended for human consumption, whether at a municipal site, a business, or a private supply.

Selective by design

What sets SIR-110-HP apart is its carefully tailored functionality. The resin greatly increases selectivity for nitrate while greatly reducing interference from sulfate ions, a common problem that prematurely shortens the working life of less specialized anion resins. That selectivity makes it a strong performer in waters where competing ions would otherwise overwhelm a general-purpose resin, allowing for more predictable, efficient, and longer-lasting contaminant capture across a range of source-water chemistries.

PFAS removal

SIR-110-HP can be used to remove a wide range of PFAS species, including PFOA and PFOS, with testing showing effectiveness across many additional PFAS compounds beyond those two. Currently this is a non-regenerable application—the resin is run to exhaustion and then replaced rather than recharged. Compared with conventional activated carbon, ion exchange offers the benefit of reduced contact times and longer throughputs, which can translate to a smaller equipment footprint and fewer media changeouts over the life of a system.

• Supplied in 50 lb quantities

Because PFAS treatment depends heavily on source-water chemistry, a thorough review is recommended before sizing a system. Levels of TOC, VOC, and individual PFAS compounds are needed, along with the basic background chemistry such as chloride, sulfate, and alkalinity, plus any co-contaminants like uranium, perchlorate, chromate, or arsenic that could influence PFAS removal. Because the bed is run to exhaustion, sampling at intervals helps confirm performance and pinpoint changeout before breakthrough reaches the treated water. Spent media from PFAS service should be handled and disposed of according to local requirements rather than landfilled casually. For municipalities, businesses, and water professionals tackling these emerging contaminants, ResinTech SIR-110-HP is a proven, certified ion-exchange media for reliable PFAS and nitrate reduction.
