The Drum Screen PWL TanFlow TFS for countless applications in industrial water and wastewater treatment16 Nov 2013
Increasing fees for sewage water make high demands on in-plant sewage treatment plants. The externally fed drum screen TFS is a product to face manifold challenges in the field of liquid solid separation.
Within the inlet chamber the incoming medium is homogenized and the flow velocity reduced. The dammed up water passes a weir and runs through the wedge wire sieve drum while the solids are picked-up by the rotating drum and transported to a scraper. Being statically dewatered they are removed from the drum.
At the bottom of the drum the water enters, thus causing a wash-back-effect which serves in addition to clean the sieve. The outlet chamber is equipped with a discharge pipe. In addition to the scraper, there is a spray bar inside the drum which operates in intervals. If necessary, the cleaning effect can be increased with hot water.
