Metals in the Environment: Toxic Metals Removal

Section 14. METAL WASTES BIOLOGICAL REMOVAL AND CHEMICAL RECOVERY OF METALS FROM SLUDGES

Utilization of sewage sludge on land is an appealing sludge disposal method. The reasons are not just because of the environmental and economic constraints associated with other disposal methods such as incineration and landfilling, but also because the sludge is beneficial both as a soil conditioner and as a fertilizer [1,2]. However, the major limitation with land application of sewage sludge...

Metals Removal Technologies for Stormwater

This study, on innovative methods for the capture of metals from stormwater, focused on two major areas of investigation: media filters and swales. The test water for both the filters and the swales was a stormwater which was collected from a parking lot during wet weather events. The characterization of the stormwater showed that the most prevalent metals detected in the runoff were iron, zinc...

Cadmium removal using waste residue generated after recovery of base metals from manganese nodules

The laboratory scale investigations on Cd removal characteristics of waste manganese leach residue (wMNR), generated by reduction roasting – ammonia leaching of manganese nodules have been studied. Adsorption studies show rapid kinetics of Cd adsorption. About 90% of total Cd adsorption occurs within 15 min contact time and equilibrium is attained within 30 min. The quantity of Cd adsorption in...
