The Plate Frame Filter is a widely used solid–liquid separation equipment designed for efficient filtration of suspensions in chemical, pharmaceutical, food processing, and industrial applications. It works by using filter plates and frames to separate solids from liquids under pressure, delivering clear filtrate and high filtration efficiency.

As a reliable and cost-effective filtration solution, plate frame filters are ideal for batch processing where high clarity and stable performance are required.

What Is a Plate Frame Filter?

A plate frame filter consists of alternating filter plates and frames arranged in a stacked structure. Filter cloth is placed between the plates and frames, forming chambers where slurry is pumped under pressure.

During operation:

• Liquid passes through the filter cloth

• Solid particles are retained in the chambers

• Clean filtrate is discharged through outlet channels

This simple yet effective structure makes it suitable for a wide range of industrial filtration tasks.

Key Features of Plate Frame Filter

• High filtration efficiency with clear output liquid

• Simple mechanical structure for easy operation

• Strong pressure resistance for stable performance

• Replaceable filter cloth for flexible use

• Suitable for fine and coarse particle separation

• Corrosion-resistant materials available

• Easy maintenance and long service life

Working Principle

The plate frame filter operates through pressure-driven solid–liquid separation:

1. Slurry is pumped into the filter chambers

2. Pressure forces liquid through filter cloth

3. Solid particles are trapped in the frame cavity

4. Filtrate flows out through discharge channels

5. Filter cake is formed and removed after cycle completion

This batch filtration process ensures high clarity and efficient separation.
