TLDR
In this paper, a reverse osmosis desalination system with an RO membrane, an intake leading seawater into the chamber, and an outlet leading brine out of the chamber was presented.Abstract:
A pressure exchanger and a method for pressurising a first fluid by the pressure of a second fluid wherein each fluid influences surface areas of a sliding member individually. Due to differences in sizes of the surface areas, the first fluid can be pressurised to a pressure which is different from the pressure of the second fluid. The invention further provides a reverse osmosis desalination system with an RO membrane, an intake leading seawater into the chamber, and an outlet leading brine out of the chamber, wherein the seawater is pressurised by the brine in a pressure exchanger of the above mentioned kind.read more
