| DESCRIPTION: Design, procurement, start-up
and parallel operation of a 72 m3/d air pilot activated sludge
plant and a 41 m3/d oxygen pilot activated sludge plant to compare
performance for the removal of conventional parameters, AOX,
chlorinated phenolics, resin and fatty acids and toxicity at
a bleached kraft mill. Findings after nine months of operation
under numerous operating conditions concluded that there was
no appreciable difference in performance between the two systems.
The findings were used to size the full scale treatment facility
to maximize AOX and chlorinated phenolics destruction. |
