•Case Study: Ozone Reduces Micropollutants
By ITT Fluid and Motion Control
A intensively used river like the Ruhr serves as drink- and process water catchment area for several million people as well as for business and industrial establishments. In addition it is also a recipient of treated residential and commercial waste waters. These waste waters contain several organic micropollutants that can not or only insufficiently be removed by traditional waste water treatment in municipal sewage.
The sources for such micropollutants are various: Hormones, pharmaceuticals, cosmetics, pesticides, industrial base materials and final substances as flame retardants and coatings are commonly found.
Due to the tight regional coupling between sewage disposal and drinking water supply in this watershed a scientific research program was implemented to survey the processes required to effectively prevent the emission of organic pollutants. Especially the effects as well as the costs of adapted municipal sewage plants on river's water quality should be determined hereby.
Against this background the ministry of environment and conservation of the federal state of North-Rhine-Westfalia MUNLV supported the realization of three large scale plants to establish an additional treatment step in a municipal sewage plant in the greater Ruhr area.
