Ro uf membrane is the most robust and excellent technology in ultrafiltration technology. The diameter of hollow fiber uf membrane is 0.5-2.0mm, the diameter is 0.3-1.4mm, and the wall thickness covers the micropores. The molecular weight of the retained substances shows that the relative molecular mass of the retained substances can reach 1000 to hundreds of thousands. The source water is pressurized and fluidized on both sides or the inner cavity of hollow fiber uf membrane to generate external pressure and internal pressure. The ultrafiltration membrane is a dynamic over-consideration of the whole process, and the compounds left over can be discharged with the liquid, which is not easy to block the surface of ro uf membrane, and can run continuously for a long time.
ro uf membrane can block bacteria, but cannot kill bacteria. No matter how good the retention rate is, the bacteria in the clean range cannot be guaranteed for a long time. If there are bacteria, it is likely that a lot of bacteria will multiply. Immediate damage depending on water quality. For example, the Aspergillus flavus clusters of transparent color linear milky white flocs in some pure water products are mainly caused by the pollution of ultrafiltration systems water treatment by the bacterial environment. Therefore, the natural environment and filtration systems must be sterilized on time. The operating cycle of sterilization depends on the water quality of the water supply. For the general domestic water in the metropolis, 7~10 days in summer, 30~40 days in winter, and 20~30 days in spring and autumn. When local surface water is used as the water source, the sterilization cycle is short. Sterilized drugs can be 500~1000mg/L sodium hypochlorite solution or 1% hydrogen peroxide solution circulating fluidity or soaking for about half an hour.
