Emergency tank
At production sites where particularly strong temporary fluctuations in the load of the waste water are possible, the equalisation basin can be extended by an emergency tank. Waste water with a particularly high load or strongly deviating properties is not directed into the equalisation tank, but into the emergency tank with the help of automated measurements in the inflow. Once the inflow values are within the norm, the heavily loaded wastewater stored in the emergency tank is successively fed into the equalisation tank. This prevents the plant from being overloaded by temporary peak loads and ensures a qualitatively and quantitatively homogeneous inflow into the plant.
