An apparatus that treats salt-containing water by reverse osmosis, in which the salt-containing water is separated into a permeate stream and a concentrate stream, includes an inlet for the salt-containing water; an outlet for the permeate; an outlet for the concentrate, and a reverse osmosis device, wherein the inlet and the outlets are integrated into a base unit adapted for installation in a positionally fixed manner, and the reverse osmosis device is an exchangeable unit detachably connected to the base unit.

Device and method of preparing salt-containing water by reverse osmosis

A method of operating a membrane separation device in a continuous flow process includes in the membrane separation device, separating a supply liquid into a first partial stream and a second partial stream, wherein flow rate of the second partial stream and/or recovery rate of the second partial stream is influenced by at least one influencing variable that varies during operation, and varying the flow rate of the first partial stream to compensate for a change of the at least one influencing variable to control flow rate and/or recovery rate of the second partial stream to a preset value.
