AbstractThis research studied the destruction of organic halides initially attached to sludge solids resulting from the secondary treatment of Kraft wastewater. The sludge solids were evaluated for Adsorbable organic halide (AOX) in static benthal deposits as a function of overlying water and the reduction in organic loading on static benthal sludges was compared with the resuspended and completely mixed deposits. Organic chlorine on the sludge was most effectively reduced under full strength Kraft wastewater. There were no significant increases in inorganic chloride content in the overall system in spite of decrease in total organic chlorine. The sum of sludge, water and gas-phase halides was not constant across the sludge/water system but decreased by at least 50% in each of the reactors.
