Equalisation basin

The characteristics of industrial wastewater in particular are subject to strong fluctuations during the course of the day. Production-dependent flushing processes, among other things, can cause significant changes in the volume, pH value, temperature and organic load of the wastewater over the course of the day. To cushion these extreme values, the waste water is first collected in mixing and equalisation tanks and actively aerated with submersible motor, surface or membrane pressure aerators. In downstream anaerobic processes, aeration is dispensed with and the wastewater is merely homogenised with top- or side-entry agitators.

 

A possibly necessary conditioning of the wastewater for subsequent process steps is also possible (e.g. pH-adjustment or heating).
