Abstract

Stabilization/solidification (S/S) process is routinely used for the final treatment of the hazardous wastes prior to land disposal. This process is used for treatment of hazardous waste especially heavy metals sludge. In this study CEMENT and SILICA FUME were used to stabilize hexavalent chromium present in the ELECTROPLATING SLUDGE. The degree of CHROMIUM STABILIZATION was evaluated using the Toxicity Characteristic Leaching Procedure (TCLP) Test and Compression Test. The specimens were prepared based on various cr+6 concentration in sludge (12, 6, 1 gr/l) and ASTM C109/C 109M-95 standard. The results show that the Cr contaminated in leaching solution for 12 and 6 g/l Cr+6 in sludge is more than maximum contaminated level (5 mg/l) in TCLP test after 28 days curing but the results of Cr+6 fixation percent show that the mean percent of Cr+6 fixation is 87% and this percent seems to be acceptable for the present situation of ELECTROPLATING SLUDGE disposal in Iran. Another obtained data showed that the partial replacement of CEMENT with 10% SILICA FUME increase the efficiency of Cr+6 fixation and compensate any negative effects caused by sludge on CEMENT hydration. It should be mentioned that the Compressive strength amount of all samples are more than the minimum EPA compressive strength for stabilized material (3.5 kg/Cm2).
