Efficient automatic gradient density fiber filter core technology is the use of asymmetric fiber bundle material as the filter material, one end of the loose fiber tow,
The other end of the fiber tows fixed in the proportion of solid body larger, filtration, the larger proportion of the solid core played a role in the compaction of fiber tow, at the same time, due to smaller nuclear size, the filter section of the uniform distribution of voids The effect of small, thereby enhancing the capacity of the bed filter interception. So that the filter bed with a high filtration porosity, small specific surface area, high filtration rate, large amount of interception, filtration and high precision, when suspended in the water flow through the fiber filter surface, the van der Waals gravity and electricity, suspension Solid and fiber bundle adhesion is far greater than the adhesion with quartz sand, help to improve the filtration rate and filtration accuracy.
Backwashing, due to the difference between the core and the proportion of filaments, the tail fiber with the backwash water flow and swing and swing, resulting in a strong drag force drag; filter
The collision between the material also exacerbated by the fiber in the water by the mechanical force, the irregular shape of the filter material in the backwash water flow and airflow under the action of rotation, strengthening the backwash filter by the mechanical shear Shear force, the joint action of the above-mentioned several kinds of force results in the solid particles attached to the fiber surface is easy to fall off, thereby enhancing the degree of filter cleaning, so asymmetric fiber filter media at the same time with the particulate filter backwashing function .
