Fiber ball filter media is a spherical filter with knotted fibers. Compared to conventional rigid filters. It has the advantages of good elasticity, no floating, a long service life, and low pressure drop. During the filtering process, the spaces in the filter layer are lined. The flow pressure is always low, which is the pore distribution structure of an ideal filter material.
