Name: Filter Press
Brand: JX Filtration

Description

JX Filtration offers a full range of filter presses from laboratory-scale units with 0.16 m² filtration area to large industrial models exceeding 400 m², with flexible customization options to suit various sludge types and throughput requirements across municipal and industrial wastewater treatment, mining, chemical, food, and pharmaceutical applications—high-pressure, automated, and built for long-term reliability.

A filter press is a batch-operated solid-liquid separation device that uses external pressure—hydraulic or mechanical—to force liquid through filter cloth while retaining solids as a compressed cake. Our portfolio includes plate-and-frame filter presses, chamber filter presses, and diaphragm (membrane) filter presses, each suited to different cake dryness targets and cycle time requirements. The diaphragm filter press represents the next generation of pressure filtration, delivering significantly drier cake and shorter cycle times than conventional designs.

Working Principle

Filling Stage: Slurry is pumped into the chambers formed between the filter plates. Filter cloth lines each chamber, retaining solid particles while filtrate passes through and exits via drainage channels.
Filtration & Cake Formation: As slurry continues to fill the chambers under pump pressure (typically 0.5–1.6 MPa), solids accumulate on the cloth surface forming a cake. Continued feed pressure compacts the cake and forces out additional moisture.
Membrane Squeeze (Diaphragm Models): For diaphragm filter presses, each plate is equipped with a flexible elastomeric membrane. After initial filling, compressed air, gas, or water inflates the membrane, applying secondary mechanical pressure directly onto the cake surface. This forces out residual moisture that conventional pressure alone cannot remove, producing a much drier final product.
Discharge: Once filtration is complete, the hydraulic system releases the closing pressure, plates are separated, and the cake is discharged by gravity or scraper. The filter cloth is then cleaned for the next cycle.

Advantages

Superior cake dryness – Delivers 60–70% solids by weight, sometimes higher; diaphragm models achieve even drier cakes than conventional filter presses
Clear filtrate – Produces low-TSS filtrate, often below 50 mg/L without additional polishing
Heavy-duty construction – Built with heavy-duty steel frames, corrosion-resistant polypropylene plates, and wear-resistant feed pipes for abrasive and corrosive slurries
Flexible plate configurations – Plate sizes from 400 mm to 2000 mm, with recessed-chamber and membrane plate options
Multiple automation levels – Manual, semi-automatic, or fully automatic hydraulic systems to match operational preferences
High mechanical strength – Diaphragm plates manufactured from high-quality polypropylene with reinforced structures, ensuring excellent chemical resistance and durability
Customizable filtration parameters – Plate size and number, chamber volume, diaphragm material, cloth type, hydraulic pressure range, and automation level all tailored to throughput and cake dryness targets
Low operating cost per tonne of solids processed – Particularly effective for fine-particle slurries that are difficult to settle by gravity
