Fiber balls are suitable for deep treatment and fine filtration of various water qualities. They are flexible, compressible, have large porosity, and strong pollution interception ability. When working, the pores of the filter layer are sparse at the top and dense at the bottom, which conforms to the pore distribution of the ideal filter layer. The specific gravity is slightly greater than that of water, and it is easy to backwash. The material is excellent and has strong wear resistance and chemical corrosion resistance.
High-efficiency fiber balls have large dirt-carrying capacity, good filtration effect, and are regenerable; they are used for deep treatment and fine filtration of various water qualities.
Product advantage
- Light weight, high strength, stable physical and chemical properties, durable.
- The filaments floating with water make the gap between fillers variable and not easily blocked by biofilm.
- Large specific surface area, strong activity and good treatment effect.
- The gap of the filter layer gradually becomes smaller along the flow direction, which is more in line with the porosity distribution of the ideal filter material from the top to the bottom.
