Belt filter presses are manufactured as either two-belt or three-belt units. The current preference is that belt filter presses have three belts, which enables the gravity zone to operate independently from the pressing zones. Belt filter presses basically have three different zones:1. gravity zone,2. medium pressure zone (wedge zone), and3. high pressure zone (shear zone).Solids must be conditioned with polymer prior to being applied to a belt filter press. The polymer is used to release the water from the solids so that most of the water is removed on the gravity zone and additional water is then removed in the pressing zones.
