PHYSICO–CHEMICAL AND GENOTOXIC ANALYSIS OF DAIRY INDUSTRIAL EFFLUENT

Abstract

India is the highest milk producer of the world. Dairy industries discharge wastewater which is characterized by high chemical oxygen demand (COD), biological oxygen demand (COD), nutrients, and organic and inorganic contents. Such wastewaters, if discharged without proper treatment, severely pollute water bodies and disrupts complete ecosystem. This paper presents the physico -chemical characteristics of waste water from the Dairy Industry. The waste water from the Dairy Industry is characterized by pH, COD (Chemical Oxygen Demand), BOD (Biological Oxygen Demand). BOD noted in Jan’ 12 and July’ 12 after ETP was 320 ± 26.76 and 355 ± 78.99 while COD range from 954 ± 86.18 to 982 ± 67.57. Study is also done for their genotoxicity analysis by Ames mutagenicity assay. Mutagenecity ratio of dairy wastewater samples noted was below 2.
