Abstract—Global environmental pollution is one of the major issues, griping earth day by day. The dairy industry effluent was the second most important single source of pollution in streams. Dairy is one of the major agriculture industries and dairy wastewater problem is larger in developing countries because all milk is processed industrially. The effluent discharged by raw milk quality control laboratories are more complex than the ones commonly generated by diaries factories because of the presence of the certain chemicals sodium azide or chloramphenicol which are used for preserving milk before analysis. The environmental impact of these factories can be very high, especially due to the discharge of very large wastewater with high content of organic matter and nutrients (nitrogen and phosphate). Dairy is having particular characteristics of effluents and hence has the different effluent related problems. These problems can be revealed only after the factual study of various physico-chemical characteris. In the present study physico- chemical parameters like color, temperature, pH, DO, TDS, SS, TS, BOD, COD, chloride, Sulphate, oil and Grease taken into account. Total 24 samples of dairy effluents were collected and subjected for analysis for consequent five months from January to May. The study revealed that the dairy effluent is slightly alkaline in nature. The high BOD and COD values obtained by the analysis of dairy effluents indicate the presence of heavy load of organic substances. It is very important that proper waste water treatment systems should be installed.
