BIOREMEDIATION OF DAIRY WASTE WATER FOR NITRATE REDUCTION

Dr. Neha Sharma* and Aditi Dwivedi

ABSTRACT

The dairy industry being one of the growing industries in India which produces high amount of effluent per unit of production. It is one of those sectors which are the largest producer of waste water where it is directly allowed to flow in rivers or agricultural lands. This waste water has large amount of organic and inorganic load. This organic load is basically constituted of milk (raw material and dairy products), reflecting an effluent with high levels of chemical oxygen demand (COD), biochemical oxygen demand (BOD), oils, grease, nitrogen and phosphorus. Hence, degradation of these compounds from source itself is necessary which can be achieved by bioremediation. Bioremediation is an environmental clean-up technique that uses microorganisms for degrading recalcitrant chemicals by utilizing them as metabolic substrate. The present study was based at screening of effluent adapted bacteria from untreated dairy waste BOD, COD, nitrate and phosphate were estimated. It was observed that there was reduction of 85.5% in nitrate content by Bacillus sp.
