  • Reverse osmosis arrangement
    Patent number: 12151209
    Abstract: A reverse osmosis arrangement is described, the first chamber (5) having a first port (7) and a second port (8) and the second chamber (6) being connected to a permeate outlet (9), wherein the first port (7) is connected to a first pump (13). Such a reverse osmosis arrangement should be operated with high efficiency. To this end the second port (8) is connected to a second pump (14).
