Abstract
In a small-volume reverse osmosis system with a reverse osmosis module, a concentrate line leading from the reverse osmosis module to an outlet line, a permeate line leading from the reverse osmosis module to a storage tank, as well as a permeate pump connected to the concentrate line and to the permeate line with a displacement unit and two control channels, the invention proposes that two valves that are alternately switched by the displacement unit () depending on the position be integrated into a joint control slide and control channel opening combination.
