How often should the reverse osmosis system be cleaned?
In general, RO systems should be cleaned when standardized flux decreases by 10-15%, or system desalination rate decreases by 10-15%, or operating pressure and interval pressure difference increases by 10-15%. The cleaning frequency is directly related to the degree of system pretreatment. When SDI15<3, the cleaning frequency may be 4 times per year. When SDI15 is around 5, the cleaning frequency may be doubled but the cleaning frequency depends on the actual situation of each project site.
