Reverse osmosis(RO)is used for desalting brackish water,the EOR of the system is crucial for improving its economic benefits. This paper investigates the main factors that influence the EOR of RO. The laboratory plant is designed and put into pilot tests. The results show that the EOR of the system can up to 85.5% under the required water quality. While it prefers to construct by stages and upgrade for the large scale RO system with wide water qualities. This program is significant for EPC performance of mega desalting project.
