An arrangement for separating a fluid from admixtures has at least a first and a second separation unit. The separation units are of the type using an increased pressure or pressure difference for their function and have improved performance with increased pressure. The second separation unit is supplied with the fluid by a pressurising pump device. The first separation unit furnishes fluid of reduced concentration of admixtures to the pressurising pump device. 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 or from an outlet of the second separation unit for fluid of increased concentration of admixtures. Overall, the concentration of admixtures in the fluid supplied to the second separation unit is decreased, leading to an increase in overall performance.
