Wastewater characterization is an integral part of treatment and management strategies for industrial effluents. This paper outlines the results of detailed wastewater characterization studies conducted for a tannery in Sheikhupura, Punjab. The results of this study demonstrated that the composition of tannery wastewater could change continuously due to inherent nature of tannery operations. In general, tannery effluent was alkaline in nature and highly polluted in terms of organic, solids, sulfates, sulfides and chromium content. Basic ingredients of tannery effluent i.e. high alkalinity and substantial portions of BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand) and other pollutants in particulate form rendered it suitable for enhanced pollutant removals at primary stage of treatment using suitable coagulants.
