Belt Filter Press Systems for Sludge Dewatering

As sludge is conveyed along the belt, ploughs roll it around to help water drain out. Before dropping down to the next stage, guide plates position the sludge towards the middle of the belt and ensure nothing is squeezed out the side of the filter. A second gravity thickener repeats the process before sludge is fed into a pressing zone.

Biosolids Technology Fact Sheet: Belt Filter Press

Belt filter presses can be used to dewater most biosolids generated at municipal wastewater treatment plants and are a common type of mechanical dewatering equipment. Using mechanical equipment to dewater solids may not be the most cost effective alternative for wastewater treatment plants operating at less than about 4 mgd.

Belt Filter Press – Water and Wastewater Treatment

For dewatering of all kind of sludge. The belt filter press is composed of two units, the pre-thickener and the sludge press. The pre-thickener performs the initial solid/liquid separation stage, taking sludge solids concentration from 0.5-3% up to 5-15%.

Belt Filter Press | Komline-Sanderson

A Belt Filter Press is a sludge dewatering device that applies mechanical pressure to a chemically conditioned slurry, which is sandwiched between two (2) tensioned belts, by passing those belts through a serpentine of decreasing diameter rolls.


Heavy duty drying filters typically utilize a system of air boxes which direct a cushion of air to the underside of the belt. Light duty washing filters typically utilize a system of wear belt support stations similar to that used for vacuum


Periodic hot-water flushes further clean the belt screen by removing oil and grease that may accumulate over time. An optional screw press dewaters the collected screenings between 20-40% dry solids while screened wastewater continuously passes through the unit.
