Belt filter Menardi

Dual Belt Filters

These are sludge dewatering devices that apply 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: gravity zone, where free draining water is drained by gravity through a porous belt; wedge zone, where the solids are prepared for pressure application; and pressure zone, where medium, then high pressure is applied to the conditioned solids.

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

Typical Applications:
- Food processing wastes
- Pulp & Paper wastes
- Chemical sludges
- Pharmaceutical wastes
- Industrial waste processing sludges
- Petrochemical wastes
