Bottom sediment-river water samples were studied to determine the extent of biodegradable matter and to examine the reduction of COD, TKN and TOC by using of warburg and aerated batch reactor. Warburg studies were conducted to study the Oxygen Uptake Rates, Reaction Rate Constants and CBOD. Bacth reator studies were conducted to determine the reduction of COD, TKN and TOC. Results from the batch recator study indicate high concentration of COD in samples. Less than 10 precent of the Organic Carbon was found to be biodegradable in 48 hours of Warburg experiment. Appreciable Immediate Oxygen Demand of sediments suggests that dredging of the river bottom is likely to deplete dissolved significantly in the river water.
