Abstract

In order that, in conventional reverse osmosis drinking water treatment apparatuses, the membrane operates without significant counter-pressure, it is proposed to transport the permeate by a pump (4) into a pressure accumulator (7), without significant counter-pressure being able to form at the RO-module exit (12). <IMAGE>
