Title

Leaching Characteristics Of Metal Finishing Sludges.

Abstract

A synthetic metal finishing wastewater containing five target metals (Cd, Cu, Ni, Pb, Zn) was subjected to three chemical precipitation processes (hydroxide, soluble sulfide, and insoluble sulfide) for metal removal. All three treatment processes achieved compliance with the technology-based effluent limitations established in 1983 by EPA for the industry. The resulting sludges were examined by the EP Toxicity Test concentration criteria with respect to at least one metal. Significant differences were observed with respect to copper and lead, however. The copper and lead leachate concentrations were much less for the sulfide-based sludges than for the hydroxide sludge.
