Moving Cloth Filter Press for Fully Automatic Dewatering

Moving Cloth Filter Press for Fully Automatic and Efficient Sludge Dewatering

The Moving Cloth Filter Press is an advanced solid–liquid separation system designed for industrial and municipal sludge treatment applications. By combining intelligent automation with innovative moving cloth technology, this filter press delivers high dewatering efficiency, low cake moisture, and reduced operating costs, meeting the growing demands of modern sludge management.

This filter press operates using only PAM and PAC as conditioning agents, without the addition of lime, iron salts, or special additives. As a result, the filter cake moisture content can be reduced to below 60%, helping users significantly lower sludge transportation and disposal costs. With a single filtration cycle of 40–50 minutes, the system achieves high throughput and stable performance while maintaining a compact footprint.

Designed for fully automatic operation, the moving cloth filter press enables automatic cake discharge without manual intervention. The filter cloth does not adhere to the sludge, allowing continuous and reliable discharge and supporting unattended operation. This automation greatly reduces labor requirements and improves operational safety.

Performance Advantages

Wide Application 

This filter press is suitable for industrial sludge, municipal wastewater sludge, domestic sewage sludge, and drinking water treatment sludge, providing flexible solutions across multiple industries. 

High Efficiency with Low Chemical Consumption

By optimizing the filtration process and minimizing chemical usage, the filter press delivers high processing capacity while maintaining consistent dewatering results within short cycle times. 

Innovative Moving Cloth Discharge System

Unlike traditional filter press designs that rely on gravity and manual assistance, this system uses synchronously moving filter cloths. During discharge, all cloths move downward and upward around the bottom roller, effectively separating the cloth from the cake. This process converts surface adhesion into linear separation, reducing bonding force and enabling complete cake discharge in less than one minute. Compared with conventional filter press equipment, discharge time is reduced by over 97%. 

Automatic Synchronous Cloth Cleaning

The filter press features automatic, high-pressure cloth backwashing that can be performed multiple times per day. All cloths are cleaned simultaneously rather than sequentially, reducing cleaning time from 30–60 minutes to under 1 minute. The folded-cloth linear cleaning method ensures deep cleaning, extends cloth service life, and lowers maintenance and consumable costs. 

With its intelligent control system, low-moisture dewatering performance, and advanced moving cloth design, this filter press provides a reliable, efficient, and cost-effective solution for industrial-grade sludge dewatering and long-term operation.
