Membrane Filter Press
The membrane filter press is defined by its ability to perform a secondary mechanical dewatering stage. Its filter plates incorporate elastic membranes, typically made of reinforced rubber or polypropylene. After the initial filtration cycle under feed pressure, these membranes are inflated with high-pressure water or air. This expansion applies uniform, isostatic pressure directly onto the filter cake, forcibly removing additional capillary water and achieving a significantly lower final moisture content compared to non-membrane plates.
This two-stage process provides decisive advantages where cake dryness is paramount. The secondary squeeze reduces the volume and weight of the solid product, lowering downstream costs for drying, transportation, or disposal. The membrane filter press is particularly effective for processing fine, compressible, or valuable materials that require maximum solid recovery. Its core value lies in this enhanced mechanical dewatering capability, making it a specialized solution for demanding applications in minerals, chemicals, and precision separation processes.
Core Advantages
- Achieves the lowest possible cake moisture via high-pressure membrane squeezing.
- Provides uniform, isostatic compression for consistent dewatering across the entire cake.
- Reduces downstream processing and disposal costs through superior volume reduction.
- Highly effective for dewatering fine-particle and compressible material slurries.
- Increases overall system throughput with a more efficient two-stage dewatering cycle.
Design Features
- Two-Stage Dewatering Process
The defining operation includes an initial pressure filtration and a secondary membrane squeeze. High-pressure fluid is injected behind the membranes to inflate them, applying direct pressure to the filter cake for final dewatering.
- Diaphragm Plate Construction
Filter plates are manufactured with integrated, sealed elastomer diaphragms that form a separate pressure chamber. Designed to withstand repeated high-pressure inflation and deflation cycles over a long service life.
- High-Pressure Squeeze System
Equipped with a dedicated high-pressure circuit, including pumps, accumulators, and valves, specifically designed to deliver and control the fluid pressure required for effective membrane inflation and cake compression.
- Hydraulic Closure & Plate Support
A heavy-duty hydraulic system provides the force to securely close the plate pack and maintain reliable seal integrity against the high internal pressures generated during both filtration and membrane squeeze operations.
