Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a fiber ball filter. Background Art

[0002] Fiber ball filters use fiber balls or modified fiber balls as filter media. Fiber ball media is made of bound fiber filaments. Compared to traditional rigid granular filter media, fiber ball media offers advantages such as greater elasticity, resistance to buoyancy, larger voids, longer operating cycles, and reduced head loss. During the filtration process, the voids in the filter layer gradually decrease along the direction of water flow, more in line with the ideal pore size distribution of filter media, characterized by larger pores at the top and smaller pores at the bottom. They also offer high efficiency, rapid filtration rates, large interception capacity, and excellent filtration results. They can be regenerated through air and water backwashing, and as such, are widely used in the filter industry. However, they suffer from several issues: uneven water distribution in the upper filter area, which can easily cause localized overload in the filter media area; unstable operation; and poor treatment results.
