Sludge Dewatering belt 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.
The sludge dewatering belt have the characteristics of good water permeability, air permeability and non-revealed sludge, acid-resisting and alkali-resisting. Because of theirs 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.

3. Filter Belt Features
1. Produced by imported woven machine, the fabrics have great stability and strength.
2. Acid-resisting, alkali-resisting, wear-resistant, high temperature-resisting, long lifetime.
3. The raw material of special polyester and woven structure, the fabric surface is smooth so that slag discharge and recycling.
4. The fabric has large tensile strength and strong wrinkle resistance, not transformative, no deviation.
5. The joint gluing of fabric is well-made and use imported latex, not easily to fall off.
4. Filter Belt Applications
Polyester synthetic filter mesh screen for dewatering is mainly used for sludge treatment in the food processing industry and sewage treatment factories, such as paper making, printing and dyeing, washer wrinkle fabric factory, etc. Industries listed below:
• Filtration
• Food cleaning and processing
• Coal plants
• Mining tailing disposal
• Sludge dehydration
• Juice squeeze (wine and juice production)
• Water treatment plants
• Ceramics
5. Another spiral press filter belt that can be used for sludge dewatering
Spiral press filter belt is made of polyester spiral dryer fabric which is filled with stuff to reduce the air permeability and intensive the opening,hence to reduce the material loss from the mesh opening.
Polyester Spiral Press-Filter Fabrics are mainly used in paper making, printing and dyeing, food, pharmaceutical, ceramics and solid-liquid separation industries like sludge dehydration.
