How the Membrane Squeeze Filter Press Works
Membrane Filter Press Working Principle
The core innovation of the membrane filter press working principle lies in the secondary dewatering stage. After the initial filtration phase, where slurry is pumped into the chambers and filtrate passes through the filter cloth, the membrane plates are inflated.
- Feeding: Slurry is pumped into the filter chambers at controlled pressure (0.6-1.0 MPa). Solids are retained by the filter press membrane cloth, forming a cake.
- Initial Filtration: Similar to a chamber press, filtrate passes through the cloth and exits the machine.
- Membrane Squeeze (The Key Difference): Once the feed pump stops, a squeezing medium (compressed air or water) is pumped behind the flexible membrane of the membrane plate (up to 2.0 MPa). This inflates the membrane, physically compressing the filter cake to squeeze out remaining moisture.
- Air Blow (Optional): High-pressure air is blown through the cake to remove final residual liquid.
- Discharge: The hydraulic system opens the plate pack, and the dry cake is discharged automatically. Automatic cloth washing system (optional) prepares for the next cycle
This two-stage process ensures maximum dewatering efficiency, making it the preferred solution for applications requiring the driest possible cake.
The squeezing pressure can be adjusted based on slurry characteristics, making this the ideal filter press to remove moisture from fine sand, sludge, or biological waste.

Frequently Asked Questions
Have More Questions? Our technical team is ready to provide detailed, personalized guidance.
Q1: What cake moisture can a membrane filter press achieve for mining tailings and municipal sludge?
A: For mining tailings, membrane presses typically reach 18–25% moisture — suitable for dry stacking. For municipal sludge, 45–55% versus 55–65% from a recessed chamber press. Actual results depend on your slurry; send us a sample or analysis report and we state the expected moisture in the proposal.
Q2: How long do membrane plates last, and what does replacement cost?
A: Reinforced polypropylene membrane plates typically last 2,000–5,000 cycles depending on slurry abrasiveness and squeeze pressure. Membrane replacement (diaphragm only) costs a fraction of a full plate; we include a spare-parts price list with every quotation.
Q3: Can I retrofit my existing chamber filter press with membrane plates?
A: Often yes, if your frame, hydraulic system, and plate size are compatible. Send us photos of your existing press with the plate size and model, and we will assess retrofit feasibility and cost.
Q4: What squeeze pressure and medium (water or air) do your membrane presses use?
A: Standard squeeze pressure is 1.0–1.6 MPa. Water is the default medium (stable, incompressible, safer); compressed air is available for sites without water supply. The medium is selected based on your utilities and slurry characteristics.
Q5: What maintenance does a membrane filter press require?
A: Routine checks: hydraulic oil level, filter cloth condition, membrane integrity (inspect for tears or leaks). Cloths are replaced based on filtrate clarity; membranes are replaced when squeeze pressure cannot be maintained. We provide a maintenance schedule and spare-parts list with each machine.
Q6: How do I choose the right filter cloth for my slurry?
A: Cloth selection depends on particle size, pH, temperature, and chemical composition. We match cloth material (PP, PET, PA) and weave to your slurry. For abrasive or corrosive feeds, we recommend specific weaves — share your sludge analysis, and we recommend the right cloth.
Q7: How does cycle time compare to a conventional chamber press?
A: The membrane squeeze phase adds 5–15 minutes but reduces total cycle time by 30–50% because the squeeze achieves target dryness faster than extended filtration alone. Net result: more cycles per day from the same plate area.
Q8: What does a membrane filter press cost, and what affects the price?
A: Main cost drivers: plate size (500–1500 mm), number of chambers, automation level (manual / semi-auto / fully automatic PLC), squeeze medium, and material specifications (316L wetted parts for corrosive slurries). Send us your daily volume and target dryness for a sized quotation within 48 hours.
