High Quality Industrial Water Treatment System and Belt Sludge Dewatering Machine

What is a Belt Filter Press?
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. The machine can actually be divided into three (3) 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.

Working Principle

Its operating principle is to condition the feed sludge with a polyelectrolyte and drain the flocculated sludge over an endless, horizontal porous filter belt. The thickened sludge is then sandwiched by a second filter belt before further dewatering by a series of decreasing diameter rollers. Final moisture removal is achieved by shear rollers arranged to give minimum 180 degree belt wrap in order to optimize dewatering.
