1. The basic principle of uf membrane filtration

Uf membrane module adopts professional internal pressure membrane separation technology to separate at normal temperature and low pressure. It has the advantages of low energy consumption, high precision, high water production rate, strong anti-pollution function, etc. It can reasonably filter out harmful substances such as bacteria, colloidal solution, suspended solids, corrosion, and biopolymer organic compounds in water.

The series of polypropylene hollow fiber ultrafiltration membrane, which are modified materials with high toughness and high wear resistance, are selected, which are non-stop, large in flux, and anti-pollution. There is no need for organic chemical dispersion cleaning, and the flux can be repaired according to the recoil force. The hydraulic load of each component is symmetrical, there is no dead angle, and the pollutants are easier to discharge during backwashing and chemical water treatment. It is integrated into various water bodies, the water production is clear and transparent, and the SDI stability is not greater than 3, which is better than the water seepage regulations of the reverse osmosis system. The design is compact, the total area is small, and the modularity is conducive to expansion, automatic operation, and maintenance-free work.

2. Matters needing attention in the application of uf membrane filtration

Uf membrane module can intercept bacteria, but not kill bacteria. No matter how good the interception rate is, there is no long-term guarantee of bacteria in the clean area, and bacteria are likely to multiply. Uf membrane filtration can intercept bacteria, but not kill bacteria. No matter how good the interception rate is, it will not guarantee a clean area of bacteria for long periods of time. If there are bacteria, it is likely that a lot of bacteria will multiply. Immediately endanger water bodies.

Hollow fiber ultrafiltration membrane should be carefully placed and maintained. Because it is a high-precision device, it should be carefully installed and placed. If the component is out of use, it should be rinsed with cold water first, and then added with 0.5% formaldehyde solution for disinfection and sterilization. The sealing performance is good, for example, the components need to be protected from cold in winter, otherwise the components are likely to be damaged.
