A membrane filter press dewaters gold and copper concentrate to 8-12% moisture using 0.6-1.0 MPa feed pressure and 1.5-2.0 MPa membrane squeeze, versus 12-18% from a chamber press alone. PP cloth and automation are standard above roughly 20-30 t/day.
Municipal plants typically generate 0.06-0.09 kg dry solids per person per day. A 10,000 PE plant needs roughly 0.6-0.9 t/day (630-800 mm press); a 500,000 PE plant needs roughly 30-45 t/day (1250-1500 mm, often multiple units).
An automatic filter press typically costs $18,000-$140,000 more than a manual one but saves 15-35 minutes of labor per cycle. In a worked two-shift, 6-cycle/day example, labor savings pay back a $35,000 automation premium in roughly 14-22 months.
For mining tailings, a filter press typically delivers 15-30% cake moisture versus 65-80% moisture from a decanter centrifuge, at 5-15 kWh/t versus 8-25 kWh/t power draw. Filter presses suit dry-stack targets below 20-25% moisture; centrifuges suit high-throughput continuous bulk dewatering.
Indicative 2026 FOB China filter press prices range from about $6,500 for a manual 630 mm chamber press to $150,000+ for a fully automatic 1500 mm membrane press. Plate size, filter area, plate type, and automation level are the four biggest price drivers. Request a quotation for exact figures.
Typical filter cake moisture ranges from about 20% for membrane-pressed mining tailings and ceramic slip up to 55% for chamber-pressed municipal sludge, with membrane filter presses consistently producing cake 10-15 percentage points drier than chamber presses across every industry.
