Sludge Treatment and Conveying

SD – SDF - Filtering and Dewatering unit. Sludge Thickener and screw press

SD - SDF range is an enclosed high performance filtration and dewatering system. It utillizers a central screw and an external filter element to gradually increase pressure to produce dry solids. With electrical, water polymer uasage (when necessary), and high capture rates the system is very cost effective.

The SD - SDF range can be constructed entirely of stainless steel.
