โœฆ Synopsis


The reverse osmosis treatment of bleach effluents from pulp and paper manufacturing is becoming of increasing importance because of environmental considerations. Investigations on the treatment of bleach effluent with three thin-film composite reverse osmosis membranes are presented. Membrane fouling was significant and was only partially controlled by the manufacturers recommended cleaning procedures. Membrane rejections of both inorganic and organic components were above 90% for total solids concentrations in the range 5-30 g/l.

ZUSAMMENFASSUNG

Die Umkehr-Osmose-Behandlung von Bleichabwassern bei der Zellstoff-und Papierherstellung gewinnt, aufgrund yon Rucksichtsnahmen auf den Umweltschutz, immer mehr an Bedeutung. Untersuchungen der Behandlung yon Bleichabwassern mit drei zusammengesetzten Dunnschicht-Umkehr Osmose-Membranen werden vorgelegt. Eine bedeutende Membranverschmutzung trat auf und liess sich nur teilweise durch die vom Hersteller empfohlenen Reinigungsverfahren unter Kontrolle hal ten. Die Ausscheidung yon anorganischen und organischen komponenten durch die Membran lag oberhalb yon 90% fur vollkommen geloste Feststoffkonzentrationen im Bereich von 5-30 g/l.
