REMOVAL OF TRACE METALS FROM WASTEWATER BY TREATMENT WITH LIME AND DISCARDED AUTOMOTIVE TIRES

Discarded automotive tires (DAT), a solid waste disposal problem of enormous proportions, may provide the answer to another environmental headache -- the removal of trace metals from wastewaters. Experiments were designed to evaluate the feasibility of using discarded automotive tires in conjunction with lime to remove aluminum, cadmium, chromium, cobalt, copper, iron, lead, manganese, mercury, nickel, silver and zinc from aqueous solutions. Continuous bench-scale studies showed that removals in excess of 99.5 percent for most of the metals can be achieved by treatment with lime and DAT. Rubber is as effective as activated carbon, is cheaper and is easier to dispose of. Furthermore, the use of DAT reduces the amount of lime required which, in turn, leaves less sludge for dewatering and disposal. Therefore, the potential of DAT in the treatment of metalbearing industrial effluents and domestic wastes contaminated with heavy metals in very high.
