Evaluation of advanced treatment of sewage effluent in full scale
In this project we will implement ozonation as a method to remove pharmaceuticals, microbes and other micro-pollutants from sewage effluents. Ozonation will be implemented on full scale at a Swedish sewage treatment plant in Knivsta. This will provide us with valuable experience from practical implementation at full scale. We will also evaluate the removal of 120 pharmaceuticals, other micropollutants and microbes from the effluent. We will follow several upstream and downstream sites in the receiving river before, during and after the ozonation period in order to evaluate the effects of ozonation on the river microbial communities (including antibiotic-resistant bacteria), fish and invertebrate communities.
