Wastewater Treatment

The treatment of municipal and industrial wastewater is very important in order to ensure a high level of water protection.

Many influencing factors must be taken into account if a sewage treatment plant is to operate as intended. For instance, changes in indirect dischargers or technical or meteorological effects can seriously influence the wastewater treatment process. Knowledge and monitoring of the constituents and the technical and technological processes for wastewater treatment are prerequi-sites for the correct operation of sewage treatment plants.
