Beschreibung
Zusammenfassung:	A process for reducing the content and volume of organic matter in a wastewater stream comprises contacting the latter with a nanofiltration device so as to obtain a concentrate, and a permeate as an aqueous stream containing any salts of non-precipitable metal ions which may be present, then contacting the concentrate with a preferably backflashable ultrafiltration device, and optionally also with activated carbon. This process may be part of a broader one which also removes other components from the wastewater stream. A module comprising (a) a nanofiltration device; (b) a preferably backflashable ultrafiltration device; (c) conduit(s) adapted to convey nanofiltration device concentrate to the ultrafiltration device; and optionally (d) a vessel containing activated carbon; as well as a system for treating a wastewater stream which includes this module, also form part of the invention. ® KIPO & WIPO 2009
