How to choose filter cloth?

The maximum permeable particle size of the selected filter cloth should not differ too much from the particle size of the particles to be retained in the material, and should be appropriately selected. During the filtration process, a filter layer is generally formed. In the early stage of filtration, the filter cloth is mainly used for filtration. Once the filter cake layer is formed, a bridge is formed between the particles. At this time, the filter layer and the filter cloth are filtered at the same time. When the filtrate passes through the filter cake layer, some small particles are intercepted by the filter cake. The filtration accuracy at this time will be higher than the filtration accuracy at the beginning of filtration;
For filtration with high filtration accuracy requirements or slurry filtration without filter cake formation, when selecting filter cloth, the maximum permeable particle size of the selected filter cloth should not be greater than the particle size of the particles to be retained in the material to ensure filtration accuracy;
Permeability is the ability of the filter cloth to allow fluid to pass under different conditions, which can indirectly show the initial filtration rate of the filter cloth. For the use efficiency of the filter cloth, the existence state of the filter layer varies depending on the working conditions;
In addition, the strength should also be fully considered~
