Sewage purification filtration with fiber filter, fiber, fiber bundle

River, reservoir water, industrial waste water purification treatment with fiber filter, fiber, fiber bundle. Fiber filter and sewage repeated contact, which is not easy to precipitate removing tiny suspended solids retention and degradation of organic matter and achieve the purpose of purification. Fiber properties of light texture. High strength, good elasticity, abrasion resistance, corrosion resistance, no water absorption. The filter has the advantages of:

( 1) have sufficient chemical stability, water filtration process has no harmful ingredients;

( 2) the backwashing water gas high strength friction, collision, shear stress is not damaged and the loss of the running of the material;

( 3) years of immersion in water durability does not rot.

Comet fiber filter is composed of a large proportion of "nucleus" and "dispersion of fiber bundles, not easy to disperse. It has advantages of fibrous filtration precision high volume and pollutant, but also has advantages of particle filter backwashing washing cleanliness high water consumption and less, structure of filter bed space formed by the filter rate distribution close to the ideal filter.

Cross sectional comet fiber filter in the filter bed (level) air void distribution, ensure the filtering flow channel size consistency, the direct effect is the interception of uniform, short circuit current phenomenon can be avoided. In the longitudinal section of the filter bed (vertical) distribution of voidage from top to bottom gradually reduced, void ratio along the gradient distribution of filter bed profile is big by small, this structure is beneficial for effectively separating the solid suspended matter in water, the filter bed upper part of desorption of particle filter bed is easily in narrow channel was captured and retain.

When the comet fiber filter filter, a larger proportion of comet fiber tow to check the compaction effect, at the same time as the nucleus is small in size, the negligible effect on the uniformity of the sectional void distribution filtering, so as to improve the filter bed of the interception capacity.

Backwashing, comet fiber filter because the coma and tail fiber proportion difference, tail fiber with backwashing water and disperse and swing, have a strong rejection of drag, the collision between the filter also increased the mechanical force by the fiber in water, irregular shape of the filtering material filter material in the backwash the water under the action of rotation.
