CenterFlow Drum Screen



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.


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.
