Introduction:
The comet-type fiber filter is an innovative filter material. It uses the theory of theoretical physics, the fractal theory of nonlinear science to guide the design. Its remarkable features are asymmetric structure and fractal structure. The utility model has the advantages of high filtration precision of the fiber filter material and large interception amount, and also has the advantages of high backwashing degree of the granular filter material and low water consumption, and the distribution of the void ratio of the filter bed formed by the filter material is close to the ideal state.
Features:
Comet fiber filter material is 1-2 times longer than ordinary fiber ball, which is not easy to disperse, has higher filtering accuracy and easier to backwash. The filtration precision is more than 5 microns, the recommended filtration rate is 17-23 m/h, the residual sludge rate is less than 1-2%, and the filter bed dirt concentration is 15-35 kg/m3. Compared with the traditional sand filter, the volume is reduced by 1/2-1/3, backwash water consumption is reduced by 2/3-1/2.
