The Right Process Measurement Technology for Nitrogen Degradation

In the wastewater treatment sector, the main focus of attention is the elimination of nitrogen and phosphorus. This is a measure of the efficiency of a sewage treatment plant and is used to determine the wastewater charges. New process ideas, additional treatment methods and advanced measuring and control programs therefore repeatedly set new records. The first prerequisite for successful optimisation measures, however, is transparency. Without an insight into the microbiological processes, and without a detailed overview of their numerous interactions, it is impossible to understand what is currently happening. Transparency means knowledge of the relevant substances in the wastewater at the right time, at the right places, in the appropriate treatment phase. Appropriate recommendations about instrumentation, together with concrete data from the Markt Schwarzenfeld sewage treatment plant, can be an aid to reaching the right decisions.
