Before selecting the filter cloth, we must first do the following preparations:
1. The filtration requirements are whether the solids should be recycled to discard the liquids, the liquids should be discarded or the liquids should be discarded, or both should be discarded or both be discarded; the filter cake should contain liquid; clarification of the filtrate;
2. Solid particles in the slurry characteristics of particle size, particle size distribution, the compressibility of solid particles, particle shape, the true density of the solid.
3. Slurry liquid viscosity, density, acid reduction, oxidation - reduction, the solubility of organic matter and temperature.
4. Slurry intrinsic viscosity, density, concentration (solid and liquid ratio), particle dispersion.
5. Filter Type According to the production capacity, investment, the use of area and other specific circumstances to determine the type of filter.
