In the backdrop of lack of success achieved by the past workers in using upflow anaerobic sludge blanket (UASB) reactor for treating low-strength wastewaters, the paper highlights the importance of R&D in this area. The two main reasons behind the importance of using UASB are: (1) generation of large volumes of low-strength wastewaters, which are often disposed untreated due to high costs, and (2) the potential of stabilizing the organic wastes by producing valuable energy as byproduct. Results are presented on the successful operation of UASB in treating low-strength dairy industry wash waters [Chemical oxygen demand (COD 1200-2000 mg/L]. The reactors achieved treatment efficiency of the order of 75-85% and were able to withstand shock-loads without adversely affecting the treatment efficiency. One of the reactors which was accidentally contaminated with acid, recovered quickly.
