24 Water

Project Detail

NX Filtration has accepted this challenge and has spent the last two years developing a new generation of nanofiltration membranes aimed at removing these micro-pollutants. At the membrane technology research department of the University of Twente, new nanofiltration membranes were developed successfully at a laboratory scale. The basis of these membranes is a very thin, polymeric selective layer, which passes the pure water but rejects the micro-pollutants. This requires advanced polymers with a high charge-density, which were developed by the Department of Material Science and Polymer Technology of University of Twente.

In order to ensure the effective production of both the advanced polymers as well as the nanofiltration membranes, a sustainable and process intensive manufacturing method is required. The solution developed by NXF reduces the energy consumption in the membrane production by more than 50%. To accelerate this innovation, NX Filtration is working closely with Artecs, a local SME with proven expertise in polymer processing.

As a final validation, the membranes are installed in a system and tested by the water company Oasen. The installation is designed to minimize footprint and power consumption of the filtration process and will produce pure water as the final product. Sustainability is again the central theme in this process.
