Because of the different filter material, filter aperture is not the same. Precision filtration is a kind of filtration between sand filtration (coarse filtration) and ultrafiltration. The same form of filter material, according to the external size can be divided into different specifications. The filter material formed by the folding process has a large flux and a maximum working temperature of 60 .Precision filtration can remove suspended matter, some colloids and small particles in water.
