Impact of Aerobic Treatment with presence of PVC Media in treating of Dairy Waste Water

In any dairy plant, the quantity and characteristics of effluent is depending upon the extent of production activities, pasteurization to several milk products. In the advent of modernization, pollution problems have also emerged in various forms. Effluent treatment involving biodegradable organic wastes can be treated biologically in most cases. Activated sludge process is used in the studies. A bench scale modified sequential batch reactor is established (MSBR) consist of an inlet which is directed to a feed pump having capacity of 2L per hour. The aerobic environment in the reactor is achieved by diffused or mechanical aeration. The efficiency in removal of COD, BOD, and other parameters are checked for 24, 48 and 72 hours respectively. The ammonia removal efficiency of MSBR is 75%. The BOD removal efficiency of MSBR in presence of PVC media is 69%, COD removal efficiency is 68%. Thus the work implies that the application of PVC ring media in the treatment of dairy waste increases the treating efficiency of MSBR
