摘要:India is a country of villages with animal husbandry as one of the most important occupations of the rural population. The dairy industry involves processing raw milk into products such as consumer milk, butter, cheese, yogurt, condensed milk, dried milk (milk powder), and ice cream, using processes such as chilling, pasteurization, and homogenization. Dairy effluents contain dissolved sugars and proteins, fats, and possibly residues of additives. The current technology for treating dairy wastewaters typically consists of biological aerobic and anaerobic digestion or facultative digestion. In the present study, a natural coagulant named Moringa Oleifera, was used to treat raw dairy wastewater. The Optimum MO dosage was found for 425, 212 and 150¦Ìm to be 300mgL-1, 500mgL-1 and 500mgL-1 respectively. Optimum pH of dairy wastewater to treat by Moringa Oleifera is 7.212¦Ìm particle size Moringa Oleifera reduced COD, total solids and oil & grease to 800, 884 and 94.4mgL-1 from its initial value of 2240, 1920 and 636.8mgL-1 respectively when experiments were run under optimum condition.
