Spin-off company NX Filtration will lead the 24Water project for the development of new polymers for nanofiltering substances such as drug residues and pesticides from drinking water.

Partners involved in the 24Water project are the MESA+ Institute for Nanotechnology of University of Twente, Dutch water supply company Oasen and spin-off company Artecs.

Micro pollutants in drinking water
Although the drinking water in Western Europe is excellent, the quality is under pressure because of contamination with drug residues, pesticides and endocrine disruptors.

Existing techniques to remove these micro- and nanoparticles from the water are expensive and energy consuming. Membranes with an ultra-thin, selective polymer layer do not have these disadvantages: the water passes through this layer, but the harmful substances do not.

Proven concept on lab scale
A proof of concept already exists, on a laboratory scale. In the group Membrane Science and Technology group of University Twente, professor Kitty Nijmeijer already successfully developed nano-filtration membranes.

NX Filtration will enable the step from the lab to industrial production and large-scale application.

To achieve this, the company works closely with the group Materials Science and Technology of Polymers of professor Julius Vancso and the spin-off company Artecs, that has extensive experience in the processing of polymers and customizing those polymers for the desired application.

The project 24Water will receive one million euro from the European Union, the national Dutch government and the provinces of Gelderland and Overijssel, through the European Regional Development Fund (EFRO).
