CHARACTERISTIC STUDY OF INDUSTRIAL SLUDGE, TREATMENT AND THEIR DISPOSAL MECHANISM

Abstract

This research papers is the characteristic study and suggestive measure for disposal mechanism for the sludge. Sludge is one of the important common waste materials which is generated in tons per day from many industries. The different types of waste materials can undergo various treatment based upon its characteristics which also resulted in the variation for the treatment like Stabilization before disposal, Direct Landfill (DLF), Alternative Fuel and Raw material (AFRF), Incineration, Solvent recovery, Chemical treatment, Recycling of metals and others for the Hazardous waste management process. The various physicochemical, gravimetric and spot test were carried out in order to determine the quality of the waste and its suitability for the disposal by following different national and international methods. Further, Heavy metals were also analyzed by AAS obtained by following different methods in different forms like TM, TCLP and WLT which also indicated that the heavy metals are within the limits. Overall, the results obtained were found to be within the limits provided by the CPCB guidelines and the waste is suitable for the direct landfill disposal mechanism.
