Project “Innovative removal of medicine traces and pesticides from effluent of municipal waste water treatment plants”

A lot of waste water contains micropollutants such as medicine traces and pesticides. These compounds finally end up in municipal waste water treatment plants, where they are only partly removed during the purification process. As a results, these micropollutants end up in our surface water and finally also in our environment and drinking water, which is ecologically undesired. For this reason there is a need for sustainable innovative technology that makes it possible to selectively remove micropollutants from waste water at limited energy and investment cost.

This project comprises the development of a completely new technology for an additional purification step in municipal waste water treatment plants to remove any remaining traces of micropollutants from the effluent. The technology consists of a unique filtration and advanced oxidation process based on UV-C irradiation, ultrasound, iron electrolysis and inline measurement of water quality. The latter is important in order to dose the optimum amounts of UV-C irradiation and chemicals to the purification process at a strongly fluctuating flow and composition of the effluent stream of municipal waste water treatment plants.

This development is possible thanks to VIA 2018 Plus and an intensive cooperation and the unique expertise of the companies Water Waves, Lamp-Ion and Bightwork. The aimed project result is a validated business case for the application of the new technology at municipal waste water treatment plants of different capacities.
