Chlorinated Organics in Tropical Hardwood Kraft Pu1p and Paper Mill Effluents and their Elimination in an Activated Sludge Treatment System

The identity and concentration of major chlorinated organics in the combined effluents of the SFI Pulp and Paper Mill in Sabah, Malaysia, were determined. In the biologically treated effluent, chlorinated organics found to occur in a relatively higher concentration were trichloroacetic acid (838-9...
