Starting procedure of high-pressure pump with de-rated motor for largescale SWRO trains

The target today to produce desalinated water at the lowest cost requires the design of a small number of large RO trains in a desalination plant. The increased capacity of RO trains, operated by one high-pressure pump, has become more prevalent. The Eilat 8000 m3/d seawater RO plant incorporates one high-pressure pump and an energy recovery turbine driven by a de-rated motor on the same shaft. This pump is manufactured by Sulzer Pumpen GmbH. Low power consumption and capital cost are characteristic of this SWRO plant.
