Numerous active substances that people take or use in the household are now found ubiquitously in European surface waters and even in drinking water. Although these micropollutants, such as pharmaceuticals, hormones or biocides, only occur in low concentrations as anthropogenic trace substances, they have been shown to pose a threat to the aquatic ecosystem and to drinking water as a living resource. The R&D project Enz4Water pursues the goal to clean sewage water from micropollutants by the development and use of a textile filter equipped with immobilized laccase, a fungal enzyme. This includes investigations on the immobilization procedure, the enzymatic degradation of various model micropollutants and the design of a wastewater treatment plant on lab and technical scale.
