Efficient fiber filter

Efficient fiber filter

High efficiency fiber filter is an advanced pressure type fiber filter that uses a new type of bundle like soft filling - fibers as the filter element. Its diameter can reach tens or even several micrometers, and it has the advantages of large surface area and low filtration resistance, solving the problem of limited filtration accuracy of granular filter materials due to the particle size of the filter materials. The small diameter of the filter material greatly increases the specific surface area and surface free energy of the filter material, increases the contact opportunities between impurity particles in water and the filter material, and enhances the adsorption capacity of the filter material, thereby improving the filtration efficiency and pollutant interception capacity. In order to fully utilize the advantages of bundle fiber filtration, a pressure chamber is installed in the filter layer of the filter. Through the compression of the fibers by the pressure chamber, the cross-section of the filter layer along the direction of water flow gradually decreases, the density gradually increases, and the corresponding pore diameter and pore size of the filter layer gradually decrease, achieving the ideal deep filtration. When the filter layer is contaminated and needs to be cleaned and regenerated, the water in the pressure chamber can be discharged to keep the fiber bundles in a relaxed state, which can be easily cleaned with water.

Detailed description of high-efficiency fiber filter

The high-efficiency fiber filter is a new type of energy-saving water purifier developed through years of practice based on the principles of fluid mechanics. It uses bundled fibers as the filter material, with diameters ranging from a few micrometers to tens of micrometers. The bundled fibers have the characteristics of large surface area, strong adsorption capacity, and low filtration resistance, which solves the problems of limited filtration accuracy and high filtration resistance of granular filter materials, greatly improving filtration accuracy, efficiency, and interception capacity.

Technical characteristics of high-efficiency fiber filters

1. Fast filtering speed; 2. High filtering accuracy; 3. Low filtering resistance; 4. Small device size; 5. Large interception capacity; 6. Easy to operate, easy to maintain, and reliable to run.

Efficient fiber filters can effectively remove suspended solids in water and have a significant removal effect on organic matter, colloids, iron, manganese, and other substances in water. Widely used in industries such as electricity, petroleum, chemical, metallurgy, papermaking, food, beverages, automobiles, boilers, aquaculture, etc.

High efficiency fiber filters are suitable for circulating cooling water treatment in industries such as electricity, petrochemicals, chemicals, fertilizers, and central air conditioning.

Circulating and reusing water for swimming pools, car washing, and showers.

Circulating water treatment and source water pretreatment in the aquaculture industry.

Deep filtration in water treatment

Deep filtration in the water supply industry

Pre treatment of boiler water.

Efficient fiber filters have good applications in industry, ensuring the quality of circulating water.

Sand filter

The quartz sand filter cylinder is arranged with filter materials of different particle sizes, compacted and arranged from bottom to top according to size. When the water flows through the filter layer from top to bottom, the suspended substances in the water flow into the tiny pores formed by the upper filter material, and are intercepted by the surface of the filter material due to adsorption and mechanical flow resistance. At the same time, these intercepted suspended solids undergo "overlapping" and "bridging" effects, forming a thin film on the surface of the filter layer and continuing the filtration process. This is the so-called membrane filtration effect on the surface of the filter material. This membrane filtration effect not only exists on the surface, but also produces this interception effect when water flows into the middle filter layer. Unlike the membrane filtration effect on the surface, this intermediate interception effect is called permeation filtration.

In addition, due to the close arrangement of filter materials, suspended particles in water have more opportunities and time to collide and come into contact with the surface of the filter material when they flow through the curved channels formed by the filter material particles. As a result, the suspended particles in water and the particles of the filter material are flocculated and adhered to each other, leading to contact coagulation.

The working principle of filtration is to purify water quality through processes such as membrane filtration, permeation filtration, and contact coagulation.

Quartz sand filter is a water treatment equipment that uses quartz sand as a filtering medium to filter water with high turbidity through a certain thickness of granular or non granular quartz sand under a certain pressure. It effectively intercepts and removes suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions in the water, making the water clear. According to different water production rates, quartz sand with different mesh sizes (quartz sand particles of different diameters) needs to be equipped, all of which are used for water treatment to remove turbidity, soften water, and pre-treatment of pure water. The effluent turbidity can reach below 3 degrees.

Application scope of Shiying sand filter

As a type of multi-media filter, the quartz sand filter is often used in conjunction with activated carbon filters because it can remove suspended solids and solid particles from water. Suspended solids, as well as non colloidal solid substances that are insoluble in water. Activated carbon filters can remove odor, color, chlorine, organic matter, heavy metals, synthetic detergents, viruses, and radioactive substances. It is a conventional equipment for deep water quality treatment. It is also often used as a pre-treatment for reverse osmosis filtration equipment, ultrafiltration equipment, nanofiltration equipment, microfiltration equipment, etc., to remove suspended substances and larger particles in water. Extend the service life of the secondary filtration equipment.
