Our solutions for drinking water and wastewater treatment

In the field of drinking water and wastewater treatment, we focus on biofilm and sedimentation processes.

Technical advancements have significantly improved the performance of modern trickling filters equipped with structured packings. Therefore, we are convinced that they can be beneficially used in many areas of the world – especially in regions with weak infrastructure. Read more about our trickling filters!

Lamella separators help to accelerate the settling process in primary and secondary clarification in wastewater treatment and after flocculation and precipitation in drinking water treatment. Our TUBEdek® lamellas also increase the settling area by up to 15 times the surface area, helping to save tank space.

    Concepts for gas and exhaust air treatment

    We have transferred our experience in water treatment with trickling filters to the biological treatment of exhaust air, where we see great advantages in using biotrickling filters. With lower pressure loss, these achieve a much better performance than conventional biofilters. Click here for more information on biotrickling filters.

    In gas treatment, our MASSdek® structured packings offer a lot of benefits. They are used in gas and bio scrubbers and increase the performance of your scrubber. More information about MASSdek® packings…

      Our brands – from the expert for environmental and cooling tower technology

      Our brands represent outstanding quality and reliability. Trust in our solutions:

      Our packings are made from foils that are extruded directly from the melt and embossed at the same time. Compared to production from flat foils and their subsequent forming, this process saves energy. Depending on the requirements, the centre and the edges of the foils can be extruded more strongly. Thus reinforced, they are more robust and – together with the welding process we have developed to connect the individual foils – this ensures particularly stable packings.
