1. According to the sludge property and particle size, the filter cloth that can effectively intercept sludge particles during filtration should be selected, mainly according to the pore size of the filter cloth and its permeability (permeability).
2. Press cloth of different materials should be selected according to the PH value of sludge. Generally, in order to extend the service life of the press cloth, polypropylene series filter should be used in the environment with PH value of 4-8, and nylon series filter cloth should be used in the environment with PH value of 5-8.5.
3, according to the size of the filter pressure to choose different tensile strength and elongation of the press cloth.
4. The cost of press cloth should be considered when the filtration performance of the two kinds of press cloth is similar.
