REDUCTION OF METAL CONTENT OF TREATED EFFLUENTS ABSTRACT The residual metal content of chelated heavy metal- containing effluents is reduced by carrying out a sulfide pre- cipitation process in the presence of a seed material comprising an added unchelated metal, preferably with an adjustment of pH to at least above about 9.0, with optional variations including passage through a mixed filter media comprising at least two particulate ingredients and regeneration of the used filter media. Adjustment of the pH to 11.3 or above can likewise be effective in the removal of metal from chelates. -1-
