Reliable and Safe

Altogether, there are seven on-line devices located in a central room in the central gallery. PO4-P is continually measured in the influx and PO4-P and NO3-N in the outflow, NO3-N at the denitrification outflow, PO4-P and NH4-N at the nitrification outflow.
At all of the above mentioned sites in the lines, testing pumps are installed. The testing pumps transport the respective sample in PE-pipelines to the appropriate analysing instrument.
One measuring cycle lasts half an hour. If there are two lines in operation, then a current measured value is given every hour per line.
The method of operation, the maintenance and the expenses are regularly checked.
