The purpose of this work was to look at the technical and economical aspects of acid extracting heavy metals and phosphates from municipal chemical sludges and subsequently recovering them by lime neutralization. The results showed that such a process was technically feasible, but the cost of the process was economically unattractive. The results should be valuable in assessing similar technology for removing heavy metals from municipal sludges.
