Hybrid Down Flow Aerobic Trickling Filter Bed Reactor for Treatment of Dairy Industry Waste Water

  Vijayshree,  Rohan S.Gurav

in this study dairy waste water is collected from belagavi milk union limited (BMUL) located at belagavi district. The dairy waste water industry effluents have high pH, BOD, Total solids, organic and inorganic 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 study packing Medias are used such as recycle coarse aggregate, polypropylene pall rings, and steel scrubber. The pilot scale setup was operated for varying different HRT’s of 72hours, 48hours, 24hours, 18hours, 12hours, 06hours with the different flow rate. The results obtained from this experimental study showed removal efficiency for BOD as 87.54%, alkalinity 47.11%, chlorides 49.68% , Total solids 78.64% , Total dissolved solids 79.08% , Total suspended solids 77.47%, for optimum HRT 24hours and the pH ranges from 7-10 in the final concentration. 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 80-90% efficiency in these results.

Keywords- dairy industry wastes water, packing media, and trickling filter bed reactor.
