A  Filter Press  is most commonly used to dewater sludge Made from industrial wastewater treatment plants. Filter Press Manufacturers  tell you the first stage of dewatering in a filter press is chemical conditioning. This is normally achieved by dosing a polymer into a mixed sludge storage tank upstream of the filter press. The flocculant will bind the sludge particles to larger flocs that are thicker and easier to dewater from the press. The slurry is then introduced through the center of the press where it fills the chambers between the plates. The pressure forces the liquid through the  Filter Cloth , whilst solids are retained between the plates. The filtrate flows between ridges in the plates to the corners where it discharges. The stages are as follows: 1. The chamber is empty, but has been sealed closed by the hydraulic ram. The press is ready to receive wet solids. 2. The wet solids are fed into the c...

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 ...
