It is well known that during the long-term use of stainless steel industrial filters, the surface of uf filter membrane will be covered by various harmful impurities blocked by it, and even the membrane pores will be blocked by finer impurities, thereby reducing its separation performance. Only by solving the speed problem of the rate of environmental pollution can the problem of environmental pollution be solved in essence. Even after the solution is completed, a small amount of impurities in the water will accumulate, and the separation characteristics of the uf filter membrane will be gradually impaired. Therefore, general ultrafiltration systems should create cleaning and reconditioning techniques.
⑤. Negative pressure reverse flushing method: It is a way of flushing from the negative side of the membrane to the positive side, which is very suitable for hollow fiber or capillary ultrafiltration membranes with high density layers inside and outside. It's also a viable but often risky approach. Once improperly operated, it is easy to break the uf membrane module or destroy the bonding surface of the hollow fiber or capillary ultrafiltration membrane and the adhesive, resulting in leakage.
