Abstract

Abstract Translated from German Eine Vorrichtung zur Gewinnung von Trinkflüssigkeit aus Meerwasser, verunreinigtem Wasser od. dgl. durch Osmose weist einen flüssigkeitsdurchlässigen Folienbeutel (1) auf, an dem eine flache Kassette (10) abnehmbar angebracht ist. Die Kassette (10) enthält einen genießbaren, osmotisch wirksamen Stoff, z. B. Fructose. Ihre Außenwand besteht teilweise aus einer semipermeablen Membran (12), deren Außenseite mit einer dünnen Schicht eines wasserlöslichen Materials beschichtet ist. Dadurch wird die Membran (12) vor dem Austrocknen geschützt. Die als Osmoseteil wirkende Kassette (10) kann abgenommen werden, sobald der Folienbeutel (1) mit Trinkflüssigkeit gefüllt ist. A device for extracting drinking liquid from sea water, contaminated water or the like by osmosis has a liquid-permeable film bag (1) on which a flat cassette (10) is removably attached. The cassette (10) contains an edible, osmotically active substance, e.g. B. Fructose. Its outer wall partially consists of a semipermeable membrane (12), the outside of which is coated with a thin layer of a water-soluble material. This protects the membrane (12) from drying out. The cassette (10), which acts as an osmosis part, can be removed as soon as the foil bag (1) is filled with drinking liquid.
