Belt press filter for sludge dewatering

Function & application

The belt filter (sometimes called a belt press filter, or belt filter press) is an industrial machine, used for solid/liquid separation processes, particularly the dewatering of sludge in the chemical industry, mining, food processing and water treatment. The process of filtration is primarily obtained by passing a pair of filtering belts through a system of rollers. The system takes a sludge as a feed, and separates it into a filtrate and a solid cake.

As a part in waste water treatment system, it is used for dewatering of suspended particles and residue after treated so as to avoid secondary pollution. 

It is also applicable for treatment of thickener concentration and black liquor extraction， including municipal sewage, textile printing and dyeing, electroplating, papermaking, leather, brewing, food processing, coal washing, petrochemical, chemical, metallurgical, pharmaceutical, ceramic and other industries sludge dewatering treatment.
