Method and apparatus for recovering cooling water |
| abstract |
When RO membrane treatment is performed on cooling discharge water such as discharge water of a circulating cooling water system and water recovery is performed, the cost of water treatment is reduced, and the improvement and stabilization of the water recovery rate are achieved. In water recovery in which effluent from a circulating cooling water system is treated by a water recovery system including a pretreatment film and an RO film and the treated water is returned to the circulating cooling water system, a dispersant that permeates the pretreatment film is added to the circulating cooling water system as a dispersant for dispersing scale components. By using a pretreatment film that allows a dispersant to permeate as a pretreatment film for an RO film and effectively utilizing the dispersant added to a circulating cooling water system in a water recovery system, it is possible to reduce the cost of water treatment and to improve and stabilize the water recovery rate. |
