Under certain conditions, the incoming water contains free chlorine and Other oxidants can cause serious membrane damage. Since oxidative damage is not covered by the product warranty, it is recommended to remove residual free chlorine in the pretreatment before the membrane.
< : .b, r, : >Dow reverse osmosis membrane BR anti-pollution reverse osmosis element
< : .b, r, As reverse osmosis technology is widely accepted, its application has expanded to many fields, including water sources with high microbial fouling resistance. In order to improve reverse osmosis To improve the performance of components under conditions of high microbial fouling, Dow used patented technology to chemically and physically modify the membrane and developed the R series of anti-fouling membrane components. BR is suitable for both drinking water and non-drinking water industries. The The element also adopts the company's unique element structure that shortens the length of the diaphragm and increases the number of membrane leaves. It has excellent efficiency not only in terms of water production volume, but also in terms of cleanability. The effective membrane area of BR is up to square feet. Water production volume () under standard test conditions. Using R components, users only need fewer components to achieve the designed water production volume. This makes the system more compact and reduces system accessories and installation costs. The water production volumes of BR and B and The desalination rates are the same. Therefore, in engineering transformation, replacing B element with BR can reduce system fouling, reduce system operating pressure, and extend the service life of membrane elements.
