Paper Details

Increase in demand of milk and their product many dairies of different sizes have come up in differentplaces. The dairy industry involve processing raw milk into product such as consumer milk , butter , cheese, yogurt,condensed milk dries milk (milk powder),and ice cream, using processes such as chilling , pasteurization ,andhomogenization. The typical by product of milk are buttermilk, whey, and their derivatives. The effluent are generatedfrom milk processing through milk spillage, dripping, washing of cans, tankers bottles, utensil, and equipment’s andfloors. The dairy industry generates on an average 2.5-3.0 liters of waste per liter of waste water per liter of milkprocesses. Generally this wastewater contains large quantities of fat, casein, lactose, and inorganic salt, besidedetergent, sanitizer, etc. Used for washing. These all contribute largely toward their biological oxygen demand (BOD),chemical oxygen demand (COD) and oil and grease much higher than the permissible limits. For reuse this waste waterfor irrigation and much other purpose we have to clean this wastewater up to Permissible limit by using naturalbioreactor (earthworm) by passing it through a filter media.From our experiment data it was found that there ispercentage reduction in effluent in a BOD, COD, TSS , Alkalinity, TDS, Turbidity, MPN like upto50%,60%,20%,40%,55%,15% .
