Plate and frame filter press is a type of industrial filtration equipment used to separate solids from liquids in slurry form. The filter frame and filter plate is a key component of this system with installed filter press cloth will be the filtering media on the plate and frame filter press

The Function of the Filter Frame on a Plate and Frame Filter Press
The filter frame (will work along with the filter plates) creates chambers where slurry is pumped under pressure from the filter press slurry feeding pump.
Solids are retained within the filter chambers and forming a filter cake and filtrate will flow away when pass by the filter press cloth.

Plate and Frame Filter Press Filter Frame Structure
Filter Frame Material: Typically made of corrosion-resistant material like polypropylene, stainless steel, or cast iron or other metallic material.
Filter Frame Shape: Rectangular with a empty center to allow slurry entry.
Filter Frame Thickness: Determines the volume of solids (cake thickness) that can be collected and also the total chamber capacity of the plate and frame filter press

How Filter Frame Works in the Plate and Frame Filter Press
Arrangement: Plates and frames are arranged in a sequence by mixing from filter plate and filter frame.
Slurry Pumping: Slurry enters through a feed port, filling the chambers formed by the filter frames and filter plates
Filtration: Liquid passes through the filter cloth, while solids stay inside the filter frame.
Filter Cake Discharge: After filtration, when the filter press is opened, and the filter cake will be removed.

Plate and Frame Filter Press Applications
Wastewater Treatment (municipal & industrial)
Chemical & Pharmaceutical Processing
Mining & Mineral Processing
Food & Beverage Industry
For some small capacity laboratory scale slurry,there will be special laboratory plate and frame filter press for lab test design.
Plate and Frame Filter Press Maintenance Tips:
Regular Cleaning after filter press operation: Prevents clogging and ensures efficiency.
Inspection for Wear: check filter frames which should be checked for cracks or deformation.
