This product is made of high-quality polyester fiber, which has the advantages of large sewage carrying capacity, good elasticity, no floating on the water surface, long working cycle, good filtration effect, etc. It is suitable for high-level treatment and fine filtration of various water quality.
container The bed is formed by filling fiber balls. Because the fiber balls are loose, the fiber filaments between the fiber balls in the bed can be interpenetrated with each other. At this time, the individual characteristics of the fiber balls are no longer important, and the bed is formed as a whole! The pressure on the fiber ball in the bed layer is the sum of the gravity of the fluid resistance fiber ball of the filtered water flow and the gravity of the suspended solids intercepted! Due to the elasticity of the fiber ball, the porosity of the filter layer and the filter aperture are gradually distributed from large to small under pressure, and the specific surface area of the filter material is gradually distributed from small to large! This is an ideal filtration method with increasing filtration efficiency from low to high. Suspended solids with larger diameter that are easy to filter can be trapped by the upper filter layer, while suspended solids with smaller diameter that are difficult to filter can be trapped by the middle and lower filter layers! The mechanical screening and contact flocculation functions are fully exerted in the whole filter layer to achieve higher filtration rate, sewage interception capacity and better effluent quality! The field test data of fiber ball filtration of sewage shows that when the operating flow rate is 15-40m/h, the sewage interception capacity is generally between 2-12Kg/m3, and the operating flow rate and sewage interception capacity are several times of that of the sand filter, the effluent turbidity is significantly better than that of the sand filter!
The filling height of fiber balls is generally 1. 2 meters, a natural drop of 40 cm when water enters
