What is Belt Filter Press?
Belt Filter Press is a sludge dewatering device that applies mechanical pressure to a chemically conditioned slurry, which is sandwiched between two tensioned belts, by passing those belts through a serpentine of decreasing diameter rolls.
The machine can actually be divided into three zones: the gravity zone, where free draining water is drained by gravity through a porous belt; the wedge zone, where the solids are prepared for pressure application; and the pressure zone, where medium, then high pressure is applied to the conditioned solids.
