Title: Removal of organic contaminants from coal conversion process condensates
Abstract: Experiments were carried out to evaluate treatment characteristics of a phenolic coal gasification process wastewater in which major treatment steps included solvent extraction with methylisobutyl ketone for phenol recovery and steam stripping for ammonia removal, followed by either activated sludge (AS) or powdered activated carbon-activated sludge (PAC/AS) processing. The study showed that solvent extracted wastewater did not require dilution prior to biological treatment; also, solvent extraction provided for lower effluent COD, TOC and colour for either AS or PAC/AS treatment, with the latter process showing better removal for these constituents. Activated sludge effluent showed favourable granular activated carbon adsorption characteristics, and lime-soda softening was demonstrated with PAC/AS effluent.
