Abstract

A process for the treatment of an effluent stream from a pulp mill having one or more liquor streams and one or more recovery processes for recovering useful components from spent liquor, wherein the effluent stream is contacted with anion exchange resin to remove organic compounds from the effluent stream of the mill and, after contact with the effluent stream, anion exchange resin loaded with organic compounds removed from the effluent stream is regenerated with a regeneration solution obtained from a liquor stream used within the mill and, after contact with the loaded anion exchange resin, the spent regenerant solution contains the organic compounds separated from the resin during the regeneration process and is used as feedstock in one or more of the recovery processes of the pulp mill.
