Fiber filter material
During filtration, the "comet nucleus" with high density plays a role in compacting the fiber tow. At the same time, due to the small size of the "comet nucleus", it has little influence on the uniformity of the distribution of the porosity in the filtration section, thus improving the sewage interception capacity of the filter bed. It not only has the advantages of high filtration accuracy and large sewage interception of fiber filter material, but also has the advantages of high backwashing cleanliness of granular filter material and low water consumption, forming a new filter material.
Comet fiber filter material has broad prospects in filtration technology and water treatment
The high-efficient water treatment system composed of key technologies of comet fiber filter material has advanced international level. This filter material is a new filter material formed by combining the characteristics of good sewage interception performance of fiber filter material with the characteristics of good backwashing effect of granular filter material. The most obvious features are asymmetric structure and fractal structure. The D-type filter and D-type filter tank developed with this material as the core solve the problem of unity of high-speed, high-precision filtering and large sewage holding capacity. They are characterized by wide area, variable speed, self-adaptive and high efficiency. The filtering precision is greater than 5 microns. The recommended filtering speed is 17-23 m/h, the residual sludge rate is less than 1-2%, and the sewage holding capacity of the filter bed is 15-35 kg/m3, Compared with the traditional sand filter, the volume is reduced by 1/2-1/3, and the water consumption for backwashing is reduced by 2/3-1/2.
