Polyester Sludge Dehydration Fabrics(Press-Filter Fabric)

Sludge Dehydration Fabrics(Press-Filter Fabric)

Introduction

Sludge Dehydration Fabrics is also called Press-Filter Fabrics which is mainly used for sludge dehydration, paper pulp and juice squeeze, Mine smelting, mine tailing disposal and other pressure filtration industries. They have the characteristics of good water permeability and non-revealed sludge, acid-resisting and alkali-resisting. Because of their designing structure, The sludge can be peel off easily from the filter cake, So the screen are easily cleaned and have a long working time. Mainly matching with belt type filter press, Vacuum rubber belt filter and horizontal vacuum belt filter.

Characteristics and Advantages 

Good water permeability

Good air permeability

Acid- resistance, alkali- resistance, temperature resistant

Heat resistance under 180 degrees

Waterproof polyester filter mesh for sludge dehydration with smooth surface mesh, high strength, excellent conduct electricity and saving energy;

 

Applications

Polyester synthetic filter mesh screen for dewatering is mainly used for sludge treatment in food processing industry and sewage treatment factories,such as paper making,printing and dying, washer wrinker fabric factory etc. Industries listed below: 
- Filtration
- Sludge dewatering
- Industrial draining usage
- Food cleaning and processing
