The Drum Screen PWL CenterFlow CFS is a guarantor for countless applications in industrial water and wastewater treatment26 Aug 2013
PWL Drum Screen
Increasing fees for sewage water make high demands on in-plant sewage treatment plants. The internally fed screen drum CFS is a product to face manifold problems.
The rugged drum screen is the core of the CFS. Here, the particles are retained and carefully dewatered for further discharge. 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 the drum screen machine CFS 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 CFS.
The CenterFlow Drum Screen CFS is made of stainless steel designed for liquid-solid-separation in the field of process and waste water of industries or WWTPs.
Within the headbox the flowing-in medium is homogenized and the flow velocity reduced. The headbox design guarantees for the tangential approaching flow of the inner drum surface necessary for an optimal separation process.
The solids which are larger that the drum‘s screen openings are retained. the discharge flites which are helically mounted to the inner drum provide for a solids transport to the discharge at the end of the drum.
The cleaned process waters run through the drum screen downwards and are returned to the water cycle resp. into the channel.
