Belt Filter Press

Model BPM


The PEI TRIAD Belt Press offers up to three sludge process steps in one factory assembled unit. Final polymer/sludge mixing or aging is accomplished in a top mounted mixing tank. Next in line, an efficient rotary drum thickener increases solids concentration to 6% solids before directly distributing sludge on the inlet end of the dewatering belt.

Municipal wastewater sludge is typically dewatered to 15-20% solids, some other industrial sludges to over 50% solids. The press and all major components feature Stainless Steel 304 construction for years of trouble-free operation.
