A mesophilic 50-L upflow anaerobic sludge bed bioreactor (UASB) design was evaluated for the treatment of a sugar rich effluent from the canning industry. The UASB was inoculated with 1670 g anaerobic granules to give a granule bed height of 141 mm. After the system had stabilized the hydraulic retention time (HRT) was set at 24 h, the bioreactor substrate pH poised at 7.5 to prevent rapid acidification and the chemical oxygen demand (COD) increased to a full strength of 4000 mg.L -1 .
