ultrafiltration membrane It is the most precise infiltration membrane with the highest characteristics so far. The ultrafiltration device is because the water solved by the ultrafiltration membrane can also be the most clear. The application of ultrafiltration membrane is very common. Now it is used in different industries such as medicine, food, sewage treatment, etc., and has excellent application performance (Zhongkong fiber curtain cloth membrane). The ultrafiltration membrane also needs maintenance and cleaning after application. The specific steps of ultrafiltration membrane storage are as follows:

How to preserve ultrafiltration membrane? The ultrafiltration membrane (hollow fiber curtain membrane) should be preserved after use, usually in the maintenance solution. The significance of doing so is to avoid the collapse of the ultrafiltration membrane after dehydration, which will damage the membrane structure engineering and reduce the transparency. The storage of ultrafiltration membrane is generally divided into short-term storage and long-term storage. The short-term storage is generally that the ultrafiltration membrane should be sterilized and sterilized once after it is suspended for less than 10 days. The cleaning drug is generally 15ppm (ml/L) HY-240 pesticide bactericide, and then the water valve, drain valve and regulating valve of the ultrafiltration membrane should be closed, To maintain the sealing performance and sterilization effect of ultrafiltration membrane; Long term storage generally means that if the ultrafiltration membrane is not used for more than 10 days, sterilization and backwashing shall be carried out for the ultrafiltration membrane first, and then HY-310 maintenance solution shall be introduced into the ultrafiltration membrane (hollow fiber curtain membrane) for sealed storage.

After application, the ultrafiltration membrane must be cleaned regularly, or it will endanger the process performance and service life of the ultrafiltration membrane. Regular cleaning can also maintain the excellent permeability of the ultrafiltration membrane (hollow fiber curtain membrane). The cleaning method is generally determined according to the characteristics of the ultrafiltration membrane and the type of solution, but in most cases, tap water is used for cleaning, Then use different chemical traditional Chinese medicine preparations to clean according to different conditions. How to preserve ultrafiltration membrane? The actual situation can be divided into the following categories: the raw materials of electrical building coatings can be cleaned with solubilizers containing positive ions; Water soluble architectural coatings can be cleaned with "bridge key" organic solvent; Protein deposition in the food industry can be cleaned with ruranase organic solvent, polyphosphate and aluminosilicate as basic alkali detergent; Carbonate deposition on the surface of the membrane can be eliminated by using antioxidants such as EDTA, acid and alkali. Naturally different membrane components can be cleaned in different ways. For example, tubular components can be cleaned with sponge, hollow fiber components (hollow fiber curtain membrane) can be cleaned in the opposite direction, and food membranes must also be disinfected.

The ultrafiltration membrane (hollow fiber curtain membrane) is actually not difficult to clean, and the physical cleaning is very simple. For the general detachable ultrafiltration membrane whose membrane hole is not particularly small, it can be immediately disassembled and cleaned with soft raw materials; According to the size of the membrane tube, how to preserve the ultrafiltration membrane? Suitable sponge balls can be scrubbed and cleaned with professional equipment, and this method can be repeated; Clean the ultrafiltration membrane with 30-40 ℃ boiling water to remove some thick or hot melt residues;

The storage of ultrafiltration membrane (hollow fiber curtain membrane) is very important, which will directly affect the performance index and service life of ultrafiltration membrane. Therefore, after application, the ultrafiltration membrane must be thoroughly cleaned and sterilized.
