When choosing polyester filter cloth with single filament, we should pay attention to the factors of drinking too much. Today we will learn about the influence of filter material on the selection of filter press. First let's introduce the density of a filter. Filter material consistency refers to be filtered in the liquid, contains many solid particles, the percentage of solid volume accounted for all liquid volume, the numerical is the solid content filter, filter the consistency of content. When selecting a filter press, the most important reference standard is the density of the filter. Filter press at the same time the interception of solid volume is different also, the higher the degree of dense, intercepting the volume of a solid particle accumulation is the faster, rather than the type of filter press, its storage space is different also, natural liquid consistency will affect the selection of filter press. Through the understanding of the above, we can know when selecting a filter press in the filter press filter material of filtering material requirement is relatively high, requirement can not meet the filter material, at the time of use may lead to a shortened the service life of filter press.
