During the filtration process, the gap of the filter layer gradually becomes smaller along the direction of the water flow, which is more consistent with the distribution of the porosity of the filter material from the top to the bottom; and the product can be repeatedly used for recycling, without requiring replacement, the use period can be as much as 10 years. Both maintenance costs and maintenance time.
Ten advantages of water treatment of Dandong Zhengda fiber ball filter
More product details click:
(1) Strong chemical stability, no harmful components are dissolved during the filtration process;
(2) High-strength friction, collision and shearing force of anti-helium water will not break and lose material;
(3) It is durable and non-corrosive in water for many years, and its service life is generally 5 to 10 years;
(4) The filtration resistance is small, the filtration speed is fast, and a good filtration effect can be ensured in the filtration speed range of 25-35 m/h.
(5) When the fiber bundle filter layer is filtered, the stepless variable void filter layer with the porosity gradually decreasing along the water flow direction is automatically formed, and the artificial grade is not required like the granular filter material. (6) The filter layer is ordered: fiber ball The filter material is suspended in the filter or filter tank. It is resistant to impact, no layering, no loss, and can withstand high-intensity cleaning, including large-flow gas-water combined cleaning.
(7) The sewage intercepting capacity is large, generally 5 to 15 kg/m3 filter material, which is 2 to 3 times that of the conventional filter.
(8) The small footprint and the same amount of water are produced, occupying only 1/3 to 1/8 of the traditional filter.
(9) The water consumption per ton is low, and the same amount of water is produced, and the cost is lower than that of the conventional filter.
(10) The backwashing water consumption is low, only 1 to 3% of the periodic water production. Under normal circumstances, the raw water can be used for backwashing.
Color Masterbatch is one general name for all colorful masterbatch. It includes all colors, such as red, green, yellow, blue, orange, violet so on. This masterbatches are made with color pigments and PE carrier, with some calcium carbonate and chemical additives and PE wax. The applications includes blowing film, injection, molding and extrustion so on. The colors have two kinds: one standard general colors and custom-made colors.
