Optimization of seawater RO systems design

The paper describes the configuration and operating parameters of current large seawater desalination systems.Major advances of RO seawater desalination technology that lead to a remarkable decrease of desalted water costs are evaluated. Process improvements that enable compliance with more stringent requirements of permeate water quality are discussed. Results of field tests conducted to demonstrate a new process approach are described. Some examples of process optimization resulting in lower power consumption and more efficient system operation are presented.
