Abstract: To conserve fresh water resources,the sea water reverse osmosis(SWRO) desalination technology was used in feed water treatment of 1 000 MW ultra supercritical once-through boiler in Guangdong Huilai power plants. The system output capacity, effluent quality, desalinization ratio have reached the design requirements. The results prove that SWRO can meet the request of feed water treatment of large coastal power plant. The equipments and operation condition of SWRO system were introduced. The key problems of typical SWRO system, such as pretreatment system dosage adjustment, application of energy recovery device PX, anti permeate thick drain, and sampling methods in permeate were discussed.

Key words: reverse osmosis(RO), seawater desalination, water treatment, ultra supercritical unit
