Tektoseal^® Active PFAS

Tektoseal Active PFAS combines the advantages of geotextiles with proven, particularly reliable pollutant adsorbents. In this way, you can reliably secure and remediate contaminated soils with the help of Tektoseal Active PFAS. Our large-area, permeable contaminant barriers can be installed evenly and erosion-proof on and in soils and even underwater. The fast reaction kinetics and high binding capacity of the adsorbents allow reliable application to a wide range of PFAS pollutants. Thanks to the fast pollutant absorption, it is possible to build a very thin and at the same time safe pollutant filter, which makes your project even more sustainable.

An application is possible for contaminated sites with short and long chain per- and polyfluorinated alkyl substances such as PFOA, PFOS, PFNA, PFHxA, PFHxS, PFBS and PFBA PFPeA. Our selective ion exchange resin has a demonstrably much higher pollutant absorption capacity than e.g. mineral adsorbers or many other alternative solutions on the market. If the focus of individual remediation measures is on long-chain PFAS in particular, the use of selected activated carbon can also yield advantages. Which active substance has the best properties should be investigated on a project-specific basis. Thanks to our broad portfolio of active substances, the optimal selection can be made for each project. For a more in-depth analysis of your project-specific problem and product configuration, our team of experts will be happy to assist you at any time.

Third party laboratories evidence shows that our highly efficient geocomposites with special ion exchanger have been proven to remove both short and long chain PFAS better than many other mineral adsorbents. Desorption at a later stage is also excluded due to the extremely high binding strength.

• Immediate binding of short and long chain carbon and sulfonic acids
• Highest capacity both at low and very high PFAS concentrations in the eluate
• Exclusion of later desorption due to strong binding between the pollutant and the active substance

The high effectiveness of Tektoseal Active PFAS was also proven in column tests. Here it is shown that Tektoseal Active reliably absorbs the pollutants already at the first leachate contact with high PFAS concentrations. As soon as the PFAS-enriched eluate passes the pollutant filter, the chemicals are reliably absorbed in the active geocomposite (see graph on the left).  In this way, the soil is reliably cleaned successively until it is completely washed out. We would also be happy to carry out the test with your project-specific soil sample. We look forward to hearing from you!
