Abstract: The consumption of large volumes of water and the generation of organic compounds as liquid effluents are major environmental problems in milk processing industry. The volume of freshwater required by this industry can be significantly reduced by recovering the intrinsic water present in dairy industry. This amount of freshwater will depend on the process technology. In recent years, the environmental effects of industrial activities have increased considerably, and current perspectives indicate that the trend for this problem is to be worsening. In this regard study is to treat the waste water generated from the dairy industry by constructed wetland Physico-chemical and organic parameters of water samples of the dairy were examined to determine the quality and extent of pollution. By which the pH, BOD, COD and the significant reduction in the parameters were observed and hence found more useful. In the study we found that initially the waste water sample was too alkaline but after the treatment the pH was observed near the Neutral also the BOD and COD removal efficiency 85% and 75% of and respectively was observed.
