The plant was developed on behalf of a municipial sewage treatment plant and is used as a quantity-based dosing station for the entry of an external carbon source (here acetic acid).
The dosing occurs via a redundant, self-priming pump system with flow monitoring. The control and monitoring is realized via a PLC. If the volume flow falls below a limit value, the second pump is automatically activated and incurs the acetic acid dosage.
Further technical information are given in the Data Sheet (PDF-document).
