A method and apparatus for treating sludges that have resulted from chemical treatment of sulfuric acid wastes with lime are shown. The sludges are subjected to fluidization, dilution, and acidification to solubilize solids, clarification to concentrate solids for reacidification and produce a supernatant for carbon adsorption to remove organics and color, with regeneration of spent carbon including incineration of solids, and finally incineration of the spent carbon and all other remaining unsolubilized solids.
