Separating arrangement for treatment of fluids

摘要

An arrangement for separating a fluid from admixtures comprises at least a first (36) and a second separation unit (45). The separation units are of the type needing an increased pressure or pressure difference for their function of showing improved performance with increased pressure. <??>The second separation unit (45) is supplied with the fluid by a pressurising pump device (71). <??>The first separation unit (36) furnishes fluid of reduced concentration of admixtures to the pressurising pump device (71). It is supplied with supply fluid having reduced, the same, or elevated concentration of admixtures, preferably either taken directly from an outlet of the pump device (71) or from an outlet of the second separation unit (45) for fluid of increased concentration of admixtures. <??>Over all, the concentration of admixtures in the fluid supplied to the 2nd separation unit is decreased, leading to an increase of the overall performance. <IMAGE>
