Abstract
A chlorolignin removal process has been assessed on laboratory scale u sing bleach plant effluents and waste sludges and solids from three bl eached softwood kraft mills. AOX removals between 7 and 57% were attai ned over a wide range of test conditions. Removals of colour and COD w ere 0-51% and 0-27%, respectively. Treatment efficiency was strongly m ill dependent. The removal efficiency was enhanced by addition of chem icals (lime, alum and ferric chloride) during the lignin removal proce ss (LRP) treatment.
