Fiber ball, fiber bundle filter

[Overview] The high-efficiency fiber bundle filter is an advanced filtration device with superior performance. Utilizing cutting-edge technology, it successfully addresses issues associated with fiber filter media during filtration and cleaning processes, fully leveraging the advantages of fiber materials to achieve an ideal deep-bed filtration effect. This high-efficiency fiber filtration technology overcomes the limitations of granular filter media, making it a next-generation replacement for traditional granular media filters such as quartz sand. The high-efficiency fiber bundle filter has received numerous accolades, including the National Invention Star Award, the Gold Medal at the First China Science and Technology Expo, the Gold Medal at the 45th Brussels Eureka World Invention Expo, and was promoted as a "Best Practical Technology" project by the National Environmental Protection Agency. It holds patents in China, the United States, Germany, France, the United Kingdom, Finland, Italy, Japan, and other countries. This filter effectively removes suspended solids from water and significantly reduces organic matter, colloids, iron, manganese, and other impurities. Compared to granular media filters like quartz sand, it offers higher filtration speed, precision, and dirt holding capacity, along with lower cost per ton of water treated, reduced self-consumption of water, and a smaller footprint. It is widely applicable in various industrial and domestic water treatment applications, including power, petroleum, chemical, metallurgical, papermaking, textile, food, beverage, tap water, swimming pools, and wastewater treatment. Key features include: - High filtration precision: Nearly 100% removal of suspended solids; with influent turbidity ≤20 NTU after coagulation, effluent turbidity can be controlled to near zero. - High filtration speed: Designed flow rate of 30 m/h, 3-5 times faster than traditional filters. - Large dirt holding capacity: Typically 5-10 kg/m³, 2-4 times greater than traditional filters. - Small footprint: Occupies only 1/3 to 1/2 the space of traditional filters for the same capacity. - Low self-consumption water rate: Only 1% of the periodic water production volume, compared to 3% or more for traditional filters. - High adjustability: Filtration precision, dirt holding capacity, and filtration resistance can be easily adjusted as needed. - No need to replace filter elements: Filter elements can be conveniently cleaned and restored after contamination.

[Working Principle and Structural Features] The high-efficiency fiber bundle filter is an advanced pressure-type fiber filter that uses a novel bundled soft filler (fiber) as the filter element. The filter media diameter can be as small as several tens or even several micrometers, offering a large specific surface area and low filtration resistance. This addresses the limitation of filtration precision in granular media filters imposed by particle size. The tiny filter media diameter significantly increases the specific surface area and surface free energy, enhancing the contact opportunities between impurity particles in water and the filter media, as well as the adsorption capacity, thereby improving filtration efficiency and dirt holding capacity. To fully utilize the advantages of bundled fiber filter media, a pressure chamber is integrated into the filter layer. By compressing the fibers via the pressure chamber, the cross-section of the filter layer gradually narrows along the water flow direction, increasing in density. This results in progressively smaller pore diameters and voids, achieving ideal deep-bed filtration. When the filter layer is contaminated and requires cleaning and regeneration, the water in the pressure chamber can be discharged, relaxing the fibers for convenient water-based cleaning.
