Filter press case studies and application notes across nine industries: mining, chemical, food & beverage, pharmaceutical, power & new energy, metallurgy, stone, municipal wastewater, and oil & gas.
A chamber filter press dewaters textile dyeing wastewater sludge from 2 to 4% solids to a 60 to 70% moisture cake; a membrane press reaches 50 to 55%. A 1,000 m³/day dyeing plant produces 400 to 800 kg of dry solids per day and typically needs one 1000 mm press with 50 to 80 plates.
A chamber or membrane filter press dewaters palm oil mill effluent (POME) sludge from 4 to 6% solids to a 55 to 65% moisture cake in 2 to 3 hour cycles. A 60 t FFB/h mill typically needs 150 to 250 m² of filter area with 1000 to 1250 mm PP plates rated to 90 °C and monofilament PP cloth.
A filter press for lithium battery slurry and black mass recycling uses 800 to 1500 mm PP or glass-reinforced PP plates, membrane squeeze at 1.5 to 2.0 MPa and an enclosed design. It dewaters leach residue and lithium carbonate to 15 to 25% moisture in 40 to 90 minute cycles, with acid-resistant plates rated to 90 or 120 °C.
A filter press dewaters the fine fraction of bentonite slurry from TBM tunnelling, pile-driving, and drilling mud operations to roughly 40-55% moisture cake, after an upstream slurry separation plant removes coarse spoil by screening and hydrocycloning.
A filter press dewaters electroplating heavy-metal hydroxide sludge (nickel, chromium, copper, zinc) to 65-75% moisture on a chamber press or 55-65% on a membrane press, cutting hazardous waste disposal volume by half or more compared to undewatered thickened sludge.
A pharmaceutical filter press supports GMP-oriented processing through SS304/SS316 wetted parts, closed or enclosed cake discharge, and crevice-free surfaces for cleaning validation, used for API filtration, herbal extract clarification, and activated carbon removal.
