Abstract

To provide a method and an apparatus for recovering a cooling water effluent such as blowdown water discharged from a circulating cooling water system through stable RO membrane treatment with reduced water treatment cost and improved water recovery rate. [Solution] The method and apparatus comprises: treating the effluent through a water recovery system including a pretreatment membrane and a reverse osmosis membrane to obtain treated water; and returning the treated water to the circulating cooling water system, wherein the dispersant added to the circulating cooling water system passes through the pretreatment membrane. By providing the pretreatment membrane that allows a dispersant added to the circulating cooling water system to pass through the pretreatment membrane, the dispersant added to the circulating cooling water system is effectively utilized as a dispersant in the water recovering system. This allows for stable water treatment with reduced water treatment cost and improved water recovery rate.
