is designed for filtration when solid or colloid sediments are washed over the filtering surface.
Predominantly used for rough preliminary treatment of a wide range of liquids with high content of solid phase in different industries. In 250 mm high element the filtering material in the form of a sleeve is pulled on a perforated polypropylene frame reinforced from inside with a twisted stainless steel frame. The shaped surface of the film abuts with the frame providing drainage. The particle retention effectiveness is determined with the thickness of a washed over layer and the properties of sediments. The design of washed type filtering elements enables washing over of solid phase including with addition of loosening agents such as diatomaceous earth etc. The material’s smooth and easy-to-wash surface guarantees the possibility of multiple removal of impurities by means of back-purging or washing.
