The technology of fiber ball efficient filtration system The fiber ball efficient filter built-in fiber ball filter, which filter media faster than the multi-media filter 2 to 3 times the interception capacity of multi-media filter is 2.7 times the water quality should be higher 1 to 2 orders of magnitude. Fiber ball filter with high filtration efficiency, interception of large volume, long working life, good removal of suspended solids and other characteristics. The system is suitable for water filtration and transformation projects, industrial circulating water supply, sewage reuse and other projects of rapid filtration. Under the same processing conditions, the investment in fiber ball filters and operation and management costs are the lowest. Fan-shaped fiber ball filter used in the preparation process of welding, the vibration can be involved in the welding spot, the nuclear surface at 20,000 times per second high-speed friction, the junction area instantly generate high heat to fuse the fiber itself, so the solder joint melting Knot firm, and small, so that "dead zone" to a minimum. Fan-shaped length and width of the appropriate, between the filaments will not be around the knot, with the advantages of asymmetric filter media, backwash thoroughly. Fiber ball precision filter driven by the filter layer compression motor driven special porous sieve, the filter layer to achieve compression, to ensure that the filtration filter when the filter accuracy. By mechanical compression to adjust the different compression ratio to achieve different filtering accuracy. The precision of the fiber ball precision filter is ≤1μm, reaching the level of microfiltration membrane (see Table 2), which completely solves the problem of precision filtration in low permeability oilfield. The application results of oilfield injection water injection meet the requirements of low permeability oilfield injection Water quality requirements. Compressive fiber ball filtration improves the accuracy of fiber ball filtration technology, adapts to a wider range of incoming water, replaces microfiltration membrane technology in the field of precision filtration, and can be used for reverse osmosis or nanofiltration or ultrafiltration membranes in membrane-based water treatment Pretreatment. The technical characteristics of the fiber ball filtration system are: unique fan-shaped structure, long service life of the mechanical ball; can be used for oily wastewater treatment; high filtration precision, to the level of microfiltration membrane; high degree of automation; initial investment costs and operating costs low, stable system reliable. Successfully developed a new type of oil-resistant modified fiber ball, the test showed that the instantaneous backwash water instantaneous oil content of 100 times the water inlet, backwash effect is good. According to experts, modified fiber ball filtration technology has a unique fiber fan structure, hydrophilic anti-oil, backwash regeneration simple, more thorough, according to water quality requirements, adjust the filter layer compression range to meet different filtration requirements. It is suitable for oilfield production water filtration treatment (especially for low permeable oilfield injection water treatment), heavy oilfield boiler reuse water depth treatment and oil refinery oily wastewater degreasing treatment.
