Fiber ball filter media is spherical filter knotted by fiber, compared with traditional rigidity filter, it has good elasticity, no floating, long working cycle and small head losses. In the process of filtration, filter layer gap along the flow direction is becoming smaller, which accords with the pore distribution structure of the ideal filter material. Fiber ball filter media has the advantages of high efficiency, fast filtering speed, large sewage interception capacity, good filtering effect, renewable, slightly larger than the proportion of water, easy to backwash, good material quality, strong wear resistance and chemical resistance.
