Abstract

Results based upon bench/laboratory and pilot-scale studies reveal that both biological (aerobic and anaerobic) and physico-chemical processes are feasible for the removal of leachate heavy metals. The aerobic process was shown to be superior to the anaerobic process. The process of adsorption was found to be superior to the ion exchange. The advantage of physico-chemical processes over the biological process is that the former can handle excessively high concentrations of heavy metals in the influent without the detrimental effect of toxicity. Research conducted at NJIT with fly ash and clay sorbents for the removal of heavy metals from industrial sludge leachates showed these materials to be effective with the controlled flow rates and sorbent arrangements. To date, field studies are still in scarcity. It is difficult to make any judgement on the field performance of these bench and pilot-scale studies. © 1986, Taylor & Francis Group, LLC.
