A Study on Dairy Wastewater Using FixedFilm Fixed Bed Anaerobic Diphasic

Abstract: In any dairy plant, the quantity and characteristics of effluent is depending upon the extent of production activities, pasteurization to several milk products. The anaerobic digesters in the first phase of treatment, which is followed by high rate aerobic treatment remain as the most common effluent treatment scheme for dairy plants. The Indian dairy industries is stated to have the growth at more than 15 % and poised to cross the 150 million tones per annum. The requirement for milk and milk products is keep growing in steady pace, making a significant impact on the Indian agriculture domain. The dairy industries require large quantity of water for the purpose of washing of cans, machinery and floor, the liquid waste in a dairy originates from manufacturing process, utilities and service section. The various sources of waste generation from a dairy are spilled milk, spoiled milk, skimmed milk, whey; whey is the most difficult high strength waste product of cheese manufacture. The present study, thus initiated, for evaluating a need based experimental work on anaerobic diphasic digester incorporated with bio film support systems, for treating dairy effluent. The kinetic parameters are also estimated using the experimental data.
