Belt Filter Press - Wastewater Sludge - Climate Policy Watcher

A belt filter press (BFP) is a continuous-feed sludge dewatering machine with two porous moving belts that has a gravity drainage zone and mechanically applied pressure zones. Belt filter presses have been used in Europe first for dewatering paper pulp and later modified to dewater wastewater sludge. It was introduced in North America in the mid-1970s, mainly because of its ability …

A REVIEW OF FILTER PRESS BASICS AND ISSUES VERSUS ...

THE PERCEIVED ADVANTAGE OF A LARGE FILTER AREA: BATCH FILTER PRESS VERSUS A CONTINUOUS VACUUM BELT FILTER One of the main attractions of the Filter Press is still its ability to offer quite large filter areas in a relatively small footprint. Of course they do offer much area, but given the normally long cycles, a large area is a must.
