Fiber ball

Fiber ball filter media is a spherical filter material made by bundling fibers. Compared to traditional rigid filter media, it offers advantages such as excellent elasticity, no floating on the water surface, large void spaces, long operational cycles, and low head loss. During the filtration process, the void spaces in the filter layer gradually decrease along the direction of water flow, aligning well with the ideal porosity distribution of larger upper and smaller lower pores. This results in benefits such as fast filtration rates, high dirt-holding capacity, effective filtration, regenerability for repeated use, no need for complete replacement, and time and labor savings. Fiber ball filter media can effectively capture fine suspended particles that are difficult to remove through sedimentation. The filtration rate is 3.5 times higher than that of traditional sand filter media. The media can be backwashed and regenerated, enabling automated management. Typical filtration rates are 30 m/h, with influent turbidity for coarse filtration at 100 mg/L and effluent suspended solids (SS) ≤5 mg/L; for fine filtration, influent turbidity is 20 mg/L and effluent SS ≤2 mg/L. It is widely used in high-standard water applications in industries such as oil fields, chemicals, power, and metallurgy, as well as in circulating, side-stream, and wastewater recycling systems. (I) Performance and Characteristics: This product is made from highly formalized vinylon and shaped polyester fibers as raw materials. It utilizes a large number of biological colonies attached to its surface, which repeatedly contact oxygenated wastewater, degrading suspended solids and organic matter to achieve treatment purposes. Its features include: 1. Lightweight, high strength, stable physical and chemical properties, and durability. 2. The floating fibers allow variable void spaces between the media, reducing the risk of biofilm clogging. 3. Large specific surface area, high activity, and effective treatment performance.
