Innovative and sustainable nanofiltration membranes
Our Direct Nanofiltration (dNF) membranes offer the unique combination of a low fouling hollow fiber configuration with the ability to remove micropollutants (including PFAS, pharmaceuticals and insecticides) colour and selective salts, but also bacteria and viruses from water whilst offering strong sustainability benefits.
Show case: direct Nanofiltration for potable water
With a strong color removal of over 95% we turned the highly colored river water into a crystal-clear drinking water which could not be achieved with conventional treatment methods. Important additional benefits are that this can be done in one single step, without pre-treatment avoiding the use of a significant amount of chemicals. Therefore, the resulting OPEX of approximately 0.12 $/m3 (including membrane replacement, electricity, labor and maintenance) for our direct nanofiltration installation were significantly lower than an expansion of the existing conventional water treatment installation.
