The role of ro uf membrane in water treatment process

    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.

    1. Ultrafiltration systems water treatment should be sterilized in 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.

    2. Gently handle ro uf membrane and pay attention to maintenance.
    Since the ultrafiltration membrane module is a high-precision mechanical device, care should be taken during use and assembly, not to mention damage. If the parts are out of use, first wash with cold water, add 0.5% formaldehyde aqueous solution for disinfection and sterilization, and the sealing performance is excellent. If the parts must also be protected from cold in winter, otherwise the parts may be damaged.

    3. Before application, you must read the description of the content of the article carefully, and carry out the operation process according to the application and production process of sewage treatment.

    4. Since each ro uf membrane is added with maintenance fluid before delivery, the maintenance fluid in the module should be thoroughly cleaned before application. MPa) water supply and drainage cleaning for 1 hour. Whether it is low pressure or high pressure cleaning, the drain valve of the system should be fully open. When using the water production rate, it should be checked that there are no pesticides and fungicides in the product water.
