Abstract
The invention concerns a reverse osmosis system (1) with a 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) connected on its concentrate side (10) to the concentrate outlet (5), and a booster pump between the pressure exchanger (11) and the inlet (3). It is endeavored to make the energy consumption as small as possible. For this purpose, the booster pump is made as a displacement pump.
