Improving the Quality of Wastewater To Tackle Trace Organic Contaminants: Think before You Act!

摘要

There is increasing urgency about the need to improve the performance of sewage (wastewater) treatment in order to eliminate polar organics from domestic sources that we know, or fear, are harming wildlife. The issue is taken so seriously that the Swiss Federal Government is planning to introduce sophisticated tertiary treatment to many of its sewage treatment plants (STPs) to eliminate these worrisome contaminants. Based on current knowledge, most of the proposed techniques would appear to be very expensive to build and maintain.
