ProMinent at IFAT 2016 - Elimination of man-made trace substances in municipal waste water treatment

Man-made trace substances in drinking water are a continually growing problem. These compounds, for example from cosmetics and medicines, which are very resistant to biological decomposition, enter our drinking water reserves through waste water. In many cases, clarification plants have a fourth cleaning stage to remove this category of impurities and some countries, such as Switzerland, it ...
