... (SWRO) desalination plants built before 2002 incorporated turbine-type energy recovery devices (ERDs) that were connected with a shaft to the high pressure pump. Both the pump and the ERD had best efficiency points corresponding to specific flow rates and pressures. To obtain the high energyefficiency... calculations. For this reason, Energy Recovery, Inc.

... modelled in order to check its behaviour in an advanced phase of its design. The plant will employ 288 ERI’s PX units to recover the pressure of the brine discarded from the RO membranes. This way of recovering energy is one of the most advanced and efficient now available, and its... which evidence of the plant’s safety even under the worst conditions likely to occur.

By defining the combination of high pressure seawater feed pump and energy recovery system as the core hydraulic module of SWRO plants it becomes obvious that this subsystem mainly... energy recovery systems were analyzed with respect to theire overall life cycle costs. Identifying the core hydraulic module using pressure exchangers as the advantageous ERS-concept the question of appropriate component optimization was discussed for the high pressure pump design. In th ...
