Abstract:
The invention concerns a reverse osmosis system (1) with at least one membrane unit (2) comprising an inlet (3), a permeate outlet (4) and a concentrate outlet (5), a high-pressure pump (8) that is connected to the inlet (3), a pressure exchanger (11) comprising at least one high-pressure concentrate connection (HPC), and a booster pump. It is endeavoured to achieve the lowest possible energy consumption. For this purpose, the booster pump is made as a displacement pump (16) that is arranged between the concentrate outlet (5) and the high-pressure concentrate connection (HPC) of the pressure exchanger (11).
