Application of Upflow Anaerobic Sludge Blanket (UASB) Reactor Process for the Treatment of Dairy Wastewater – A Review

The up flow anaerobic sludge blanket reactor for the treatment of dairy wastewater is often reported to be an effective method of treatment. The objective of this paper is to summarize recent research efforts and case studies in up flow anaerobic sludge blanket reactor for treating dairy effluents. The main characteristics of the dairy wastewater have been identified and the degradation mechanism of the primary constituents in dairy wastewaters, namely carbohydrates (mainly lactose), proteins and lipids has been described. Primary attention is focused on bench, pilot-scale up flow anaerobic sludge blanket reactor for the treatment of dairy wastewater effluents. Finally, areas where further research and attention are required have been identified.
