The Plate and Frame Filter Press is a core solid-liquid separation system based on the principle of high-pressure compression. Featuring a simple structure, thorough dewatering capabilities, and exceptional versatility, it is extensively applied in environmental sludge treatment, chemical processing, mining, food, and pharmaceutical industries.

Core Performance Features

  1. Exceptional Dewatering Performance

Driven by a hydraulic system delivering 0.3-1.6 MPa of high pressure, the equipment forces solid-liquid separation, effectively reducing moisture content from 95%-98% to below 60% (and as low as 30%-40% for Diaphragm types). This significantly minimizes subsequent disposal volume and costs, making it the premier choice for applications requiring high-dryness filter cakes.

  1. Extreme Material Adaptability

Unconstrained by particle size or viscosity, it excels at processing fine-grained, high-viscosity, and hard-to-filter materials such as municipal sludge, chemical slurries, and mining tailings. It is equally effective for both compressible and incompressible suspensions, offering an extensive filtration range.

  1. Significant Energy & Cost Savings

Energy consumption is only 50%-70% of that of a centrifuge, and roughly 40% lower than traditional drying processes. Equipped with variable displacement hydraulic pumps and VFD (Variable Frequency Drive) control the system optimizes power delivery based on demand, eliminating idle loss and ensuring low long-term operational expenditures.

  1. Robust Structure & Easy Maintenance

The simplified design, consisting of filter plates, frames, cloths, and a compression system, eliminates complex wear parts. Filter plates are available in reinforced polypropylene (PP), stainless steel, or cast iron for superior acid and alkali resistance. With a filter cloth service life of 6-12 months maintenance costs are kept to a minimum while ensuring a long equipment lifespan.

  1. Flexible Automation Levels

We offer a range of configurations including manual, mechanical, and hydraulic compression, as well as automatic plate shifting and PLC-programmed control. The system can automate the entire cycle—from feeding and filtration to pressing and discharging—making it adaptable for everything from small-scale batch operations to large-scale continuous production.
