Presented in this paper is the application of high efficient reverse osmosis technology in boiler make-up water system in Zhanjiang Power Plant and the comparison evaluation between the traditional and high efficient reverse osmosis technologies.The application indicates that the high efficient reverse osmosis technology has overwhelming advantage

such as a higher recovery rate (90%)

a stable and better effluent quality

less requirement of chemical cleaning

etc.It is very suitable for the power plants that have poor raw water quality and /or suffer from water shortage.
