Filter principle and instructions for efficient filter? Filter principle of efficient filter:The most commonly used method of mechanical filtration sewage treatment is that according to the different filter media, the mechanical filtration equipment is divided into two categories: Particle Media filtration and fiber filtration. Particle Media filtration is mainly used as filter media such as sand and gravel, through the adsorption effect of particle filter material and the interception effect of pores between sand particles on solid suspended matter in water body, the advantage is that it is easy to reverse, and the disadvantage is that the filtration speed is slow, generally not exceeding 7 m/h; the amount of interception is small, its core filtration layer is only the surface of the filter layer; the filtration accuracy is low, only 20-40 μm, which is not suitable for rapid filtration of sewage containing high turbidity.The high-efficiency asymmetric fiber filter system uses asymmetric fiber bundle materi
