Targeted, rapid PFAS binding and compact filter assemblies. Explore the technology, its benefits and the route from media to industrial systems.
instrAction develops filter media with specifically designed functional groups. These are chemical binding sites tailored to capture selected contaminants. The iA P series is developed for short- and long-chain PFAS.
The foundation is hydrogel chemistry: in contact with water, the polymer structure provides access to binding sites. In P media, a functionalised polyamine combines selective chemistry with a stable support. As water passes through, PFAS bind to the medium and remain in the filter.
The abbreviation iA stands for intelligent Absorber. The innovation combines selectivity, binding speed and suitability for compact filter designs.
PURPOSE-DESIGNED
PFAS can be dissolved in water. Their capture therefore relies on binding to a dedicated medium.
Water flows through the filter bed. Cartridge design and media distribution bring dissolved PFAS into contact with functional groups. Where needed, pretreatment retains particles and prepares the water for the dedicated stage.
The iA P series is designed for short- and long-chain PFAS. Accessible binding sites enable rapid capture, important at higher flow rates and shorter water–media contact times.
We monitor performance by sampling inlet and outlet water. Two consecutive filtration stages provide additional outlet control, while parallel housings increase total flow. Replacements are planned according to loading and results.
The advantages of iA are reflected in its capture mechanism and test results: high efficiency even at higher media loading rates.
Granular activated carbon uses a porous surface for adsorption. instrAction technology uses binding sites specifically designed for PFAS. The P series is developed to capture both short- and long-chain compounds.
A benefit for system design: rapid binding enables more water to be treated per unit volume of media. In system design, this creates the potential for a smaller filter bed and a more compact installation at the same flow rate.
PFAS-specific IEX uses anion-exchange media. instrAction is based on a functionalised hydrogel platform. Comparative measurements best demonstrate the differences between configurations.
In the tests shown, iA P 425 maintains higher PFAS removal efficiency than the tested IEX as the loading rate and treated water volume increase. This supports efficient media utilisation and compact industrial design.
We combine iA P BIG cartridges in multi-filter housings. Cartridge number and length determine each assembly’s capacity, while parallel housings increase the system’s total flow.
For industrial sizing, we use a range of 100–250 BV/h, adapted to water composition. BV/h expresses hourly water throughput relative to media volume. The selected loading rate and capacity are confirmed by testing the client’s water.

How selectivity worksThe existing comparative calculation shows a lower total cost for iA than for GAC and IEX. It covers investment and ten years of operation; actual costs depend on the project.
Compare CAPEX and OPEXReplaceable cartridges enable planned maintenance. We combine analysis, replacements and filter collection into comprehensive client support.
Filter cartridges and industrial systemsWe arrange collection of spent filters containing captured PFAS and their destruction by high-temperature incineration at an authorised facility, under conditions suitable for PFAS destruction.
