membrane squeeze filter press
A membrane filter press is a highly efficient solid-liquid separation device. Its filtration chamber consists of membrane filter plates or a combination of membrane plates and box-type filter plates. The equipment significantly improves dewatering efficiency and shortens the filtration cycle by subjecting the filter cake to secondary compression dewatering after filtration.
Compared to traditional plate and frame filter presses, membrane filter presses, after filtration, inject a compressed medium (such as water or air) into the membrane plates, causing the membranes to expand and further compress the filter cake, thus removing more water and achieving a higher dewatering effect.
LONGONE membrane filter presses are optimized to achieve:
- Higher dewatering efficiency
- Shorter filtration cycles
- More stable filtration performance
- Higher production efficiency

Membrane Filter Press Advantages
The membrane filter press filtration process includes filtration, cake formation, membrane squeezing, and discharge. This advanced process improves dewatering efficiency, shortens filtration cycles, and produces drier filter cakes for industrial solid-liquid separation.
Higher Dewatering Efficiency
Membrane squeezing removes additional moisture, producing drier filter cakes and improving overall dewatering efficiency.
Shorter Filtration Cycle
Membrane pressing accelerates water removal, significantly reducing filtration cycle time and increasing production efficiency.
Lower Operating Costs
Membrane plates withstand high squeezing pressure, ensuring stronger cake compression and improved filtration performance.
Flexible and Reliable Operation
Durable membrane plates, corrosion resistance, and flexible configurations ensure stable operation across diverse industrial applications.
Membrane Filter Press Filtration Process Steps
Membrane filter presses offer superior dewatering performance through membrane squeezing technology, reducing filtration cycles, lowering cake moisture, and improving operational efficiency for demanding industrial solid-liquid separation applications.
Filter Plate Closing and Slurry Feeding
The hydraulic system closes and seals the filter plates to form filtration chambers. Slurry is pumped into the chambers through the feeding port. Under pressure, liquid passes through the filter cloth while solids are retained, gradually forming filter cake.
Initial Filtration and Cake Formation
During filtration, the solid particles accumulate on the filter cloth surface to form filter cake. As filtration continues, the cake layer thickens and filtration pressure increases, allowing more liquid to pass through while retaining solid materials efficiently.
Membrane Squeezing and Secondary Dewatering
After filtration, compressed water or air enters the membrane plates, causing the membranes to expand and squeeze the filter cake. This secondary pressing step removes additional moisture and significantly improves the final cake dryness.
Plate Opening and Cake Discharge
Once squeezing is completed, the hydraulic system releases the filter plates. The plates open sequentially and the dry filter cake falls automatically due to gravity, allowing the filter press to prepare for the next filtration cycle.

FAQ
After the filtration chamber fills with slurry and forms filter cake, compressed water or air enters the membrane plates. The membranes expand and press the cake, removing additional moisture through secondary squeezing.
Most industrial membrane filter presses operate with squeezing pressures up to 25–50 bar, allowing efficient secondary cake compression and improved solid-liquid separation performance.
A chamber filter press only performs filtration, while a membrane filter press adds a secondary squeezing stage using membrane plates to further reduce cake moisture and improve dewatering efficiency.
Yes. In most membrane filter press designs, the membrane can be replaced separately. If the membrane is damaged, only the membrane needs replacement instead of the entire filter plate.
Common feeding configurations include center feed, corner feed, and top feed, depending on filtration requirements, slurry characteristics, and system design.
Membrane squeezing can reduce filtration cycle time by 30–50%, significantly improving production efficiency and throughput.
Membrane filter presses are slightly more complex than chamber presses, but routine maintenance is simple. Membranes only need periodic inspection and replacement when worn.
