Hybrid Down Flow Aerobic Trickling Filter Bed Reactor, Treatment of Dairy Wastewater


Dairy industries have indicated huge development in size and number in many nations of the world. It is also one of the most polluting industries. In this study, dairy wastewater is collected from Belagavi Milk Union Limited (BMUL) located at Belagavi district. The industries effluents of dairy wastewater which is characterized by high pH, Chemical Oxygen Demand , Biological Oxygen Demand , nutrients and organic and in organics contents. Such wastewater, if discharged without proper treatment, severely pollutes receiving water bodies. To treat this dairy wastewater, the Hybrid Down flow Aerobic Trickling Filter Bed (DATFB) reactor is developed. In this experiment study, multi filter media namely Plastic scrubber, Sponge and Polypropylene pall rings used. The reactor has sufficient space to grow microorganisms and bacteria’s. This pilot scale setup was operated for varying Hydraulic Retention Time (HRT) for 6 hours, 12 hours, 18 hours and 24 hour with different flow rate 0.02 L/min, 0.003 L/min, 0.005 L/min and 0.009 L/min. The results obtained from the experimental study showed removal efficiency for BOD as 92.4 %, COD as 87.4 % and Total Solids as 79 % for optimum HRT 18 hours. From the above results it is concluded that the Hybrid DATFB reactor gives more efficiency and good results. The filter media which is used in this reactor gives more than 90% efficiency in these results.
