Under normal circumstances, when the standardized flux decreases by 10 ~ 15%, or the system desalination rate decreased by 10 ~ 15%, or the operating pressure and inter-section pressure difference increase by 10 ~ 15%, RO system should be cleaned.
The cleaning frequency is directly related to the pretreatment degree of the system. When SDI15 <3, the cleaning frequency may be 4 times per year;
When SDI15 is about 5, the cleaning frequency may be doubled, but the cleaning frequency depends on the actual situation of each project site.
