ABSTRACT

 

In the present study the physico-chemical characteristics of sludge generated from treatment of combined wastewater of dyes and dye intermediates industries was studied. Combined wastewater of 12 unit manufacturing different type of dyes and dye intermediate was used for this study. Sludge are analyzed for pH, TDS, COD, BOD, Total Hardness, Alkalinity, Zinc, Copper, Lead, Chromium etc by leachate water preparation. Analysis of sludge on dry basis also carried out for parameters like Moisture, Loss on Ignition, Calcium, Magnesium, Iron etc. The study shows that the sludge was hazardous in nature and cannot be disposed as such for land filling. The study shows that proper handling and storage system is required for the disposal of solid waste.

 

Keywords : Dye Industries, Sludge, Leachate water, Physico-Chemical parameters, Effluent.
