FDS is structured with a filter element that consists of two types of rings: fixed ring and moving ring, and a screw that thrusts the filter element and transfers and pressurizes the sludge.
The gaps between the rings and the screw pitch are designed to gradually get narrower towards the direction of the sludge cake oulet and the inner pressure of the filter element increases due to the volume compression effect, which thickens and dewaters the sludge.
FDS comprise typical series of small, medium, large and extra large sludge dewatering units ranked by productivity (throughput) and flow rate. To select the correct unit for your needs, please download the product data sheet.
FlotLife supplies own manufactured range of automatic polymer preparation and dosing stations either as complementary products to sludge dewatering screw presses or as stand alone units. Please contact us for more information.
