Belt filter is a common solid-liquid separation equipment, in which filter cloth plays a very important role. Belt press cloths need to have high vertical and lateral liquid flow properties, excellent wrinkle resistance and mechanical stress properties. They are mostly made of synthetic fibers with good filtration properties and durability.
- Material: PP(Polypropylene) fabric, PET(Polyester) fabric.
- Weaving Methods: Plain, Twill, Satin.
- Cloth Codes Most Widely Used: PDW series, EDW series.
Description
Our Double Layer Weave fabrics are designed for belts filter. Best filtration results and enhanced lifetime is achieved by combining the functions of a fine filtration layer and a support drainage layer. Double weave technology combines fine filter fabric laminated with sturdy supporting fabric. The double-layer series belt filter cloth, with its unique material characteristics and unique product technology, has the advantages of good air and water permeability, not easy to block, and the filter cake is easy to peel off.

PDW-double layer weave fabrics dedicated for belt filter
- Double Layer Weave fabrics designed for belts filter.
- Best filtration results and enhanced lifetime is achieved by combining the functions of a fine filtration layer and a support drainage layer.
- This concept is recognized as being the most successful standard for vacuum belt filters.
This unique filter media offers the following advantages
- Best permeability due to optimal fabric design.
- Wide range of pore sizes (7-150 µm).
- Optimum particle retention, due to special pore structure.
- Excellent cake release, resulting from the special surface treatment of the fabrics.
