Fiber bundles

Fiber bundlesWhen filtering, the water level in the filter or filter tank is used to compress the filter layer by gravity from top to bottom, and the fiber bundle filter material is in a dense state, which improves the efficiency of the filter layer in intercepting impurities and ensures the quality of filtered water. During flushing, the air and water are impacted and disturbed from bottom to top, causing the bundled filter material to be in a suspended and loose state, and the adsorbed and intercepted substances in the filter layer are washed away. Thus, the state of unordered packing filtration and orderly packing backwashing of bundled fiber filter materials has been achieved. When in use, water enters from the upper part and exits from the lower part. At this time, under the action of water flow and gravity, the fiber density adjustment device pushes the fiber filter bed downwards, compressing the fiber filter layer. Its packing density gradually increases along the direction of water flow, causing the porosity of the filter layer to gradually decrease from large to small along the direction of water flow. Correspondingly, the pore diameter and pore size of the filter layer gradually decrease, thus forming a particularly ideal variable pore deep filtration state. The filtration process includes both horizontal and vertical deep filtration, effectively improving the filtration accuracy. When the filter layer is contaminated and needs to be cleaned, the cleaning water passes through the fiber filter bed in the opposite direction. Under the action of backwash water flow and cleaning air, the fiber density adjustment device drives the fiber filter bed to move upward, causing the fiber filter material to stretch upward and reach a loose state. Through the air-water mixing cleaning technology, during the process of bubble aggregation and hydraulic flushing, the fiber filter material is constantly shaking longitudinally, thereby cleaning it thoroughly and achieving the ideal cleaning effect.
