Four-Belt Filter Press for Industrial Wastewater Treatment
Product Overview
The Four-Belt Filter Press for Industrial Wastewater Treatment is a high-performance sludge dewatering machine designed specifically for industrial wastewater treatment systems, including chemical plants, food and beverage processing facilities, paper mills, breweries, and other process industries.
Featuring a four-belt pressing structure, this equipment provides stronger squeezing and shear forces, making it highly effective for treating industrial sludge with high organic content, high viscosity, or complex chemical composition. Compared with conventional belt filter presses, it delivers lower sludge cake moisture content, higher solids recovery, and more stable continuous operation, even under demanding industrial conditions.

Working Principle
After proper conditioning in the flocculation system, industrial sludge is evenly fed into the four-belt filter press.
During operation, the sludge passes through several stages:
-
Gravity Dewatering Zone – Rapid removal of free water
-
Multi-Stage Pre-Pressing Zones – Gradual compression between multiple belts
-
High-Pressure Pressing Zones – Four belts apply strong squeezing and shear forces
Dewatered sludge cakes are continuously discharged, while the filtrate is collected and returned to the industrial wastewater treatment system.
