REVERSE OSMOSIS MEMBRANE TREATMENT SYSTEM OPERATION METHOD AND REVERSE OSMOSIS MEMBRANE TREATMENT SYSTEM

摘要

In the RO membrane treatment system in which an energy recovery device for recovering energy from the concentrated water of the RO membrane device is provided, not only biofouling of the RO membrane device but also biofouling in the energy recovery device is suppressed, thereby reducing the overall system In order to improve energy efficiency and achieve stable operation, combined chlorine system and stabilization in RO water supply so that the residual halogen concentration of the concentrated water of the RO membrane device introduced into the energy recovery device is 0.1 to 10000 mg/L in terms of total chlorine concentration At least any one of bromine-based slime control agents is added.
