Abstract

Abstract Translated from German Speisewasser für eine Einrichtung (7) für Umkehrosmose wird mittels Ozon aufbereitet, indem es über ein Misch­gefäss (4), in welchem die Beladung mit Ozon erfolgt, einen Verweilzeitbehälter (5), ein Gefäss (6) zur Rest­ozonvernichtung in die Einrichtung (7) für Umkehrosmose geleitet wird. An deren Permeataustritt (9) wird ein Teilstrom abgezweigt und zur Beladung mit Ozon in eine mit einem Feststoffelektrolyten ausgerüstete Elektro­lysezelle (2) geleitet und in das Mischgefäss (4) zurück­geführt. Feed water for a device (7) for reverse osmosis is prepared by means of ozone by passing a residence time container (5) and a container (6) for residual ozone destruction into the device (7) via a mixing vessel (4) in which the ozone is loaded. for reverse osmosis. At the permeate outlet (9), a partial flow is branched off and passed to an electrolysis cell (2) equipped with a solid electrolyte for loading with ozone and returned to the mixing vessel (4).
