Abstract

The research involves measuring the pH, Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) in the waste water of Gallant Ispat Limited and Indian Glycol Limited, selected sites. The result illustrates that the height of B.O.D and C.O.D construction was found in the wastewater of GIL and IGL in summer season. Recorded pH range is between 5.8 to 6.3 (IGL) and 6.2 to 6.4 (GIL) in summer season. Recorded pH value is limit the standard permissible limit of industrial effluent. The observed value of B.O.D is 600 mg/L to 1000 mg/L (IGL) and 600 mg/L to 1000 mg/L (GIL) in summer season. The observed value of C.O.D is 3200 mg/L to 4400 mg/L (IGL) and 1920 mg/L to 3250 mg/L (GIL) in summer season. Both the recorded values of B.O.D and C.O.D are higher than the standard permissible limit of industrial effluent.

Keywords: Biological Oxygen Demand, Chemical Oxygen Demand, Industrial Wastewater, Gallant Ispat Limited, Indian Glycol Limited, pH and Standard permissible limit of Industrial effluent.
