PFAS solutions.
Selective. Modular.
From water analysis to correctly sized filtration. ECO ELEMENT combines instrAction technology with local support for your project.
Persistent substances.
A long-term water challenge.
PFAS refers to a large group of per- and polyfluoroalkyl substances. Their resistance to water, grease and heat has led to their use in industrial processes, protective coatings and certain firefighting foams.
Many PFAS break down very slowly in the environment. They can reach groundwater and surface water from contaminated soil and various discharges. This is why they are often called “forever chemicals”.
Why dedicated filtration?
Conventional mechanical and biological treatment is not designed to reliably remove dissolved PFAS. The treatment technology must be selected for the specific compounds and water composition.
iA filter assemblies use selective media to bind target PFAS. Laboratory and pilot testing establish the appropriate configuration, replacement intervals and outlet monitoring plan.
Focused on what
we want to remove.
instrAction media are based on a hydrogel platform with functional binding sites. The iA P series is developed to capture short- and long-chain PFAS.
Cartridge or column configurations adapt to flow and space requirements. Capacity is verified for the specific PFAS, water composition and required outlet concentration.
The complete process is part of the solution.
Adsorption transfers PFAS from water onto the medium. Subsequent handling is a separate, essential part of the project.
From sample to design
Laboratory analysis identifies the PFAS present and their concentrations, alongside checks of flow and water composition. Laboratory or pilot testing on actual water assesses filter performance and capacity, providing a basis for system sizing.
A solution for your water
Based on the results, we select suitable iA filter assemblies, pretreatment and the number of filtration stages. The system is tailored to required flow and outlet quality. Sampling monitors performance and informs timely filter replacements.
Destruction of spent filters
We 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. This removes the captured PFAS from the water cycle.
Higher flow rates.
The modular BIG solution.
For industry, water supply and tertiary treatment, we design multi-filter housings with iA P BIG cartridges. Capacity is adjusted through cartridge number and length, and by connecting housings in parallel.
TECHNOLOGYinstrAction
One housing is the starting point.
More housings increase flow.
Up to 28 m³/h per housing with 20 iA 40 P BIG cartridges at 200 BV/h. We connect multiple housings in parallel to match total capacity to the required flow.
Housing adaptation. The base plate is adapted to the larger diameter of BIG cartridges.
Easier maintenance. Length is also selected with replacement in mind: a wet 40-inch cartridge is heavier, so a 30-inch version may be more practical.
Dedicated iA P media capture short- and long-chain PFAS from suitably pretreated water.
Multiple cartridges per housing and multiple parallel housings allow capacity to match the design flow.
The design includes maintenance access and filter replacement at least annually, or sooner if capacity is reached.
Choose an assembly. Connect multiple units.
The table shows the flow through one housing at 200 BV/h. This is not a limit for the complete system: higher flows are achieved with multiple housings connected in parallel.
| Filters per housing | iA 20 P BIG | iA 30 P BIG | iA 40 P BIG |
|---|---|---|---|
| 1 filter | 0.7 m³/h | 1.0 m³/h | 1.4 m³/h |
| 3 filters | 2.1 m³/h | 3.0 m³/h | 4.2 m³/h |
| 6 filters | 4.1 m³/h | 6.0 m³/h | 8.4 m³/h |
| 20 filters | 14 m³/h | 20 m³/h | 28 m³/h |
Flow rates apply to the stated number of filters in each housing.
Flow relative to media volume.
BV is the filter media volume. At 200 BV/h, the volume of water passing through each hour equals 200 times the media volume.
For industrial water treatment with instrAction, the recommended range is 100–250 BV/h, as other substances present affect performance. The operating value is confirmed by laboratory testing.
A system that grows with your needs.
With parallel connections, housing flows add together. As an indicative calculation at 200 BV/h, six housings with 20 iA 30 P BIG cartridges each provide a total of 120 m³/h.
This is a sizing example, not a universal configuration. Stages, hydraulics, pretreatment and replacements are determined for the actual water and outlet requirements.

Precise measurements.
A reliable basis for a solution.
Through our partnership with instrAction, we provide access to a laboratory in Heidelberg equipped with modern, highly sensitive HPLC-MS/MS technology to measure PFAS in water.
The method combines liquid chromatography and tandem mass spectrometry: compounds are separated, identified and quantified. This allows very low concentrations of selected PFAS to be measured and compared before and after filtration.
- Water analysis: measuring selected PFAS concentrations in your samples.
- Laboratory testing: checking media suitability, flow and capacity.
- Pilot trial support: evaluating samples and results to design an industrial system.
We agree the compounds to be measured and suitable detection and quantification limits for the sample.
