Environmental Technology
With over 30 years of environmental technology experience, NSW produces extremely durable film strip clusters and grid tube blocks that can handle the load. They are used as support materials for biological wastewater treatment. Sections of our grid tubes are used as loose fill or as a compact block, serving as tower packing material, for example, for water purification systems.

BIO-NET® and SESSIL® set the standards as support media for biomass. As the support material, they are found in municipal and industrial wastewater treatment plants, that are based on the principle of a trickling filter system. BIO-NET® is also used in rotating biological contractors and submerged fixed-bed systems.

NOR-PAC® high performance tower packing material, with its excellent separation properties and its durability, provides a high-quality solution for all gas and liquid separation processes, for example in the purification of drinking water.
