How to determine the efficient filter of FFU needs to be replaced? The working principle of high-efficiency filter made in liaojing is the most commonly used method for mechanical filtration sewage treatment,Depending on the filter media,Mechanical filtration equipment is divided into two categories: Particle Media filtration and fiber filtration,Particle Media filtering mainly uses granular filter materials such as sand and gravel as filter media,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 filtration is realized,The advantage is that it is easy to counterattack,The disadvantage is that the filtration speed is slow,Generally no more than 7 m/h;Less pollution,The core filter layer is only the surface of the filter layer;Low filtering accuracy,Only 20-40 μm,It is not suitable for fast filtration of high turbidity sewage.The high-efficiency asymmetric fiber filter system uses asymmetric fiber bu
