Reliably remove PFAS with the new Grünbeck systems and protect health for the long term
News General news
Per- and polyfluoroalkyl substances (PFAS) are among the most pressing challenges in modern water treatment. Due to their extremely stable carbon-fluorine bond, they are practically not degraded in the environment and accumulate over decades in soil, water bodies, and ultimately in drinking water. As so-called “forever chemicals,” PFAS are suspected of causing health risks.
New sorbliQ filter systems from Grünbeck
At IFAT 2026, Grünbeck unveiled a new generation of filter systems designed for targeted PFAS removal. The new sorbliQ absorber systems were developed specifically to meet the requirements of water utilities, municipalities, and industry, and enable the effective absorption of both long- and short-chain PFAS compounds. This allows water quality to remain consistently below the EU limits that will take effect in the future, ensuring a consistently high standard of drinking water quality.
Triple-absorber system sorbliQ:LA – maximum efficiency through series connection
At the heart of the new product line is the sorbliQ:LA triple-absorber system in series connection. The system consists of three GRP filter vessels connected in series with side-mounted filling and draining ports. The PP front filter piping is pre-assembled on an anodized aluminum frame with leveling feet. This design allows for space-saving installation and easy maintenance.
The system uses a highly selective absorbent resin approved for drinking water, which is characterized by a particularly high absorption capacity for PFAS. The system is designed for operating pressures of 2.5 to 8.0 bar; the pressure drop at nominal flow is approximately 1.5 bar. Water temperatures up to 35 °C are permissible. Depending on the system size, nominal flow rates of 10 to 50 m3/h can be achieved. Additional series are available upon request.
MGR Circuit Principle: Maximum Capacity Utilization
The exceptional efficiency of the sorbliQ:LA is based on the so-called MGR circuit. In this system, the absorbent resin is not replaced simultaneously in all three filter vessels. Only when a PFAS breakthrough is measurable after the second or third filter is the resin in the first filter vessel replaced. The newly filled vessel is then moved to the last position in the series configuration. This rotation principle ensures optimal utilization of the absorbent material, extends service life, and reduces operating costs while maintaining high reliability.
Compliance with stricter drinking water limits
The sorbliQ:LA systems are designed for high flow rates and can be flexibly adapted to individual requirements. Thanks to the high absorption capacity of the absorbent resin, consistently high filtration performance is achieved, even with heavily contaminated raw water. This ensures that the total limit values for PFAS in drinking water, which will take effect in 2026 and 2028, are reliably met.
Sustainable water treatment for the world of tomorrow
With the new sorbliQ filter systems, Grünbeck combines efficiency, technical robustness, and sustainable use of resources. After replacement, the contaminated absorbent resin is properly disposed of and thermally recycled. In addition to PFAS removal, Grünbeck is also active in other future-oriented fields of water technology—from energy-efficient treatment to solutions for hydrogen production.
