PWL CenterFlow Drum Screen CFS

PWL CenterFlow Drum Screen CFS

Application

Increasing fees for sewage water make high demands on in-plant sewage treatment plants. The internally fed sieve drum CenterFlow is a product to face manifold problems, designed for liquid/solid separation in the field of process and waste water of industries or WWTPs.

Function

The rugged sieve drum is the core of the CenterFlow. Here, the particles are retained and carefully dewatered for further discharge. Within the inlet chamber the flowing-in medium is homogenized and the flow velocity reduced. The tangentially approached sieve surface serves to efficient fine sieving even of high hydraulic loads. Due to the drum configuration the main task can either be a fast solids discharge or a slower passage through the drum if the retained solids are to be, in addition,  washed or properly dewatered. 

With a constant rotational speed and a low drive power this sieve drum machine is a reliable component within the equipment of a plant. The high availability and the large number of varieties open up a wide range of different applications for the CenterFlow.
