Filter Press Types And Industrial Application Compatibility

As a core solid-liquid separation device, various types of filter press have evolved to address different material properties, application scenarios, and production requirements. The structural design and operational characteristics of each filter press machine must match specific industrial conditions. This article, Yuwei Filtration will discuss the structural and functional nuances of these filter press machines, offering insights into their industrial compatibility.

Basic Structural Types of Filter Press

1. Chamber Filter Press

Adopts sealed filter chamber design with evenly distributed filtration pressure. Suitable for scenarios demanding high filter cake integrity, such as gentle separation of antibiotic crystals in pharmaceuticals or precise capture of nanoparticle suspensions in electronic materials.

2. Membrane Filter Press

Integrates elastic diaphragms for secondary compression. Effectiveness depends on material compressibility. Ideal for municipal wastewater plant sludge, plant protein extracts, and pharmaceutical mycelium. Among types of filter press, this variant significantly reduces moisture content through micro-pore compression.

3. Plate and Frame Filter Press

Forms residue spaces through alternating plates/frames. Handles high-solid-content materials effectively in municipal sludge dewatering and chemical resin processing.

Special Material Filter Presses

1. Cast Iron Filter Press

Withstands >120°C temperatures for molten material separation (e.g., coal tar filtration, zinc smelting).

2. PP Coating Filter Press

Features steel frame with corrosion-resistant lining. Processes medium-to-low temperature corrosive media:

• Titanium dioxide acidolysis slurry
• Rare earth leaching solutions
• Fluorochemical sludge (PVDF lining required)
• Alumina red mud liquor

3. Stainless Steel Coating Filter Press

Carbon steel base fully clad in 316L/304 stainless steel (Ra≤0.8μm). Processes bioactive materials and moderately corrosive media under hygienic standards.

4. Stainless Steel Plate and Frame Filter Press

Combines stainless-clad frame with pure stainless plates/frames. Surface precision (Ra≤0.8μm) complies with GMP/FDA standards for pharmaceuticals, food, and fine chemicals.

Special Structural Types of Filter Press

1. Round Plate Filter Press

Radial circular plates withstand high pressure. Processes high-hardness particles in:

• Stone cutting wastewater (SiC abrasives)
• Ceramic body slip dewatering
• Kaolin clay separation

2. Skid-Mounted Filter Press

Containerized design enables mobile operation for oilfield sludge and tunneling slurry dehydration.
