摘要

The primary objective of this study was to prepare a technical survey of currently available high pressure pumps, drivers, and energy recovery devices for large reverse osmosis (RO) plants. This equipment was specified for two seawater RO plant sizes (2.5 MGD and 25 MGD) and two product recovery ratios (25 and 50 percent) operating at 900 psi pressure. Four types of drivers were considered;electric motors, steam turbines, gas turbines, and diesels. It was concluded that:pumps suitable for seawater RO systems are available in single units for plant sizes through 25 MGD;the cost and availability of energy is the most significant item in the selection of a pump driver;energy recovery can be an economic choice with a low recovery ratio and high values of energy cost, operating pressure, and plant size.
