The choice of filter cloth is very important for the filtration effect. The filter cloth plays a key role in the use of the filter press. Its performance is good or bad, and the correctness of the selection directly affects the filtering effect.
The most common filter cloth currently used is a filter cloth made of synthetic fibers. According to the material, it can be divided into polyester, vinylon, polypropylene, nylon and so on. In order to achieve the interception effect and the filtration speed are ideal, in the selection of the filter cloth, it is also necessary to select according to the particle size, density, chemical composition and filtration process conditions of the slurry. Due to the difference in materials and methods of weaving, the strength, elongation, gas permeability and thickness of the filter cloth are different, which affects the filtering effect. In addition, the filter media also includes cotton woven fabrics, non-woven fabrics, screens, filter papers, and microporous membranes, depending on actual filtration requirements.
