Polymer Comet Fiber Filter Material

Comet fiber filter media is a new type of filtering material that combines the advantages of both fiber filter media—high filtration precision and large dirt-holding capacity—

and granular filter media—high backwashing cleanliness and low water consumption. The porosity distribution of the filter bed formed by this media closely resembles the structure of an ideal filter material.

On the cross-section (horizontal) of this filter bed, the porosity is uniformly distributed, ensuring consistency in the size of water flow channels during filtration. The direct result is uniform dirt-holding capacity,

preventing short-circuiting of water flow. On the longitudinal section (vertical) of the filter bed, the porosity decreases gradually from top to bottom, forming a gradient distribution with larger pores at the top and smaller ones at the bottom.

This structure is highly conducive to the effective separation of solid suspended particles in water, meaning that particles detached from the upper part of the filter bed are easily captured and retained in the narrower channels of the lower filter bed.

During filtration, the relatively dense comet core compacts the fiber bundles, while its small size has little impact on the uniformity of pore distribution across the filtration cross-section,

thereby enhancing the overall dirt-holding capacity of the filter bed. During backwashing, due to the density difference between the comet core and the comet tail fiber bundles, the tail fibers spread out and sway with the backwash water flow,

generating strong drag forces. The mutual collisions between filter media also intensify the mechanical forces acting on the fibers in the water. The irregular shape of the filter media causes it to rotate under the action of the backwash water flow,

amplifying the forces exerted on the media during backwashing. The combined action of these forces makes it easy for solid particles attached to the fiber surfaces to detach, thereby improving the cleanliness of the filter media.
