Plate and Frame Type Sludge Filter Press
A plate and frame sludge filter press is a solid-liquid separation device that uses a hydraulic system to pressurize filter plates and filter cloth for filtration. Its core function is to dewater sludge. First, sludge is pumped between the filter plates and filter cloth. After pressurization, water is forced through the filter cloth and discharged, leaving behind dry sludge with low moisture content (filter cake). Finally, the filter cake is discharged, completing the process. This type of equipment offers good dewatering performance and has a wide range of applications. It is commonly used in wastewater treatment plants and in chemical and mining industries to reduce sludge volume and facilitate subsequent treatment.

Frequently Asked Questions
How does a plate and frame filter press work?
It uses a hydraulic system to compress a series of filter plates. Sludge is pumped into the chambers between plates, and pressure forces the liquid through the filter cloth while solids are retained to form a dry cake.
What are the primary applications for this equipment?
It is widely used in municipal wastewater treatment, chemical processing, mining, metallurgy, and any industry requiring efficient solid-liquid separation and sludge volume reduction.
What materials are used for the filter plates?
Our plates are typically made of high-quality Polypropylene or steel skeleton composite rubber (PP), ensuring high strength, corrosion resistance, and a long service life.
What is the difference between manual and mechanical compaction?
Manual (hydraulic station) compaction involves user-controlled hydraulic pressure, suitable for smaller areas. Mechanical compaction is more automated and designed for larger filter areas (up to 100㎡) and higher processing volumes.
Does the equipment hold any international certifications?
Yes, our manufacturing process and equipment are ISO quality system certified and hold the EU CE certification, ensuring compliance with international safety and quality standards.
How dry is the discharged sludge cake?
The filter press is designed to achieve low moisture content in the filter cake, significantly reducing the weight and volume of the sludge for easier disposal or further processing.
