Belt Filter Presses

A belt filter press is a bio-solids/sludge dewatering device that applies mechanical pressure to 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:

• Gravity zone where free draining water is drained by gravity through a porous belt
• Wedge zone where the solids are prepared for pressure application
• Pressure zone where medium, then high pressure is applied to the conditioned solids

Typically, a belt filter press receives slurry ranging from 1 to 4 percent feed solids and produces a final product of 12 to 35 percent cake solids. Performance depends on the nature of the solids being processed.
