Membranes enhance carbon removal in sewage micropollutant treatment

  • Research


Testing in Germany has shown the potential benefit of using an ultrafiltration membrane system to improve the removal of the activated carbon that is added during sewage treatment for tackling the problem of micropollutants, according to company Microdyn-Nadir.

One of the approaches currently used to remove micropollutants from sewage involves adding powdered activated carbon. The micropollutants adsorb to the carbon and the carbon can then be removed by using a sand filter. According to Microdyn-Nadir, one concern around this approach is that the sand filtration does not fully remove the activated carbon.
