Rajkumar V. Raikar, Neha Santi

This paper presents the experimental results of a case study on the water and wastewater quality analysis of Karnataka cooperative Milk producers Federation limited (KMF) Dharwad Milk Union (DMU), Karnataka, India. Total seven quality parameters were analyzed in the study. These quality parameters were determined for input water and wastewater discharged from each of the milk processing sections as well as for influent and effluent of treatment plant. The milk processing sections considered are milk separation section, curd section, can washing section and paneer section. The parameters obtained at every section were compared with effluent standards for dairy industry as per the Environment (Protection) Rules, 1986. The results indicate that all the quality parameters are well within the permissible limits for the discharging effluent of every section. Further, the oil and grease content was below detectable limit. However, the temperature at can washing section was 40ºC, which was more as compared with other sections. The higher temperature was maintained for quick and easy drying of cans and for effective cleaning.
