Abstract: In this paper, waste water obtained from textile and tannery industry in Delhi-NCR and other regions was characterized for basic parameters. The effluent was dark colored with unpleasant odor and acidic in nature (pH 3.2) in case of tannery industry waste and it was basic in textile waste (pH 10.5). The effluent having high organic and inorganic load showing high electrical conductivity 3575 – 7620 μS/cm in textile and 12659 μS/cm in tannery waste water. Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), Total hardness, Phenol, Cr(VI), total Cr , heavy metals like Zn, Cu and Ni were determined . The physico-chemical parameters were calculated as per the standards approved by Bureau of Indian Standards (BIS).
