The screening plant filters inorganic coarse solids from the waste water. Once a certain amount of coarse material has accumulated on the screen it is automatically removed with the so-called comb. The material is then washed, pressed and taken away for further processing.
Analogue signal converters from the ACT20C series ensure safe and effective signal acquisition for the control of rake screens, combs and other components involved in primary wastewater treatment, such as fans, motors and valves. Other signal converters in the ACT20 series can also be used in a wide range of applications thanks to their properties, such as communication capability, intrinsic safety and software configurability.
