Maintain of Ultrafiltration Water Treatment

The chlorine or sodium hypochlorite disinfectant will be used in the periodic backwashing process of the ultrafiltration membrane. In view of the oxidizing property of the residual free chlorine, a reducing agent (usually sodium hydrogen sulfite) addition system should be added at the back end of the ultrafiltration or the front end of the reverse osmosis inlet. Thereby protecting the reverse osmosis membrane from oxidative damage by the oxidant.

Function and purpose of UF Containerized System
Both microfiltration and ultrafiltration are pressure-driven separation processes that remove almost all suspended matter from the water. Ultrafiltration also removes partially dissolved organic matter, depending on the molecular weight of the organic material and the molecular weight cut-off of the ultrafiltration membrane.
Ultrafiltration membranes for reverse osmosis pretreatment typically have a molecular weight cut of 20,000 to 750,000 Daltons (O.002 to 0.05 μm). Ultrafiltration is used as the pretreatment of reverse osmosis: the process not only has good effluent quality (SDI value can generally be controlled below 3), but also can greatly improve the stability of system operation and reduce the frequency of reverse osmosis chemical cleaning. In addition, the ultrafiltration system has a small footprint and is convenient for automatic control. The reverse osmosis system using the ultrafiltration/microfiltration pretreatment process has become the development trend of the current industrial water treatment process.

Can ultra-filtered water be used directly?
The ultrafiltration water purifier uses an ultrafiltration membrane for purification treatment. This is a microporous membrane with a uniform pore size of 0.01 micron. Under a certain pressure, when the stock solution flows through the membrane surface, the ultrafiltration membrane surface Many fine pores in the dense cloth allow only water and small molecules to pass through and become permeate, and substances in the original liquid having a volume larger than the pore diameter of the membrane surface are trapped on the liquid inlet side of the membrane to become a concentrated liquid, thereby realizing the liquid solution. The purpose of purification, separation and concentration. However, it should be noted that although the ultrafiltration water purifier can remove most of the impurities in the water, it is not completely filtered out for harmful substances such as nitrosamines and bleaching powder residues that are harmful to human health, so unless the water quality is relatively good, It is not recommended to drink or to drink.
