Since the role of the hollow fiber uf membrane is to remove the impurities rich in the original solution, the uf membrane module with excellent characteristics and low interception relative molecular mass is more likely to be blocked by the environmental pollution of impurities, and the surface of the membrane will be intercepted by various kinds of Hazardous impurities are covered, and even the membrane pores will be blocked by finer impurities, thereby reducing its separation characteristics. Whether or not source water pretreatment is better, compared with the good solution to product quality problems, only by determining the environmental pollution speed at which the hollow fiber uf membrane is blocked can the environmental pollution problem be solved essentially. Even if the pretreatment is complete, a small amount of impurities in the water will be Will gradually be affected by the isolation characteristics due to accumulation over time. Therefore, the clogging of the membrane is certain, and the general ultrafiltration system should create cleaning and remanufacturing technology.
The criteria for the selection of chemical substances are that they cannot produce other chemical changes or dissolving effects with membranes and other component materials, and that they cannot cause secondary pollution due to the use of chemical substances.
