How often should the reverse osmosis system be cleaned?
In
general, when the normalized flux decreases by 10-15%, or the system
desalination rate decreases by 10-15%, or the operating pressure and the
pressure difference between sections increase by 10-15%, the RO system
should be cleaned. The cleaning frequency is directly related to the
system pretreatment degree. When SDI15<3, the cleaning frequency may
be 4 times a year; when SDI15 is about 5, the cleaning frequency may be
doubled, but the cleaning frequency depends on each item actual
situation on site.
