Abstract

Field measurements documented successful one-reactor denitrification with nitrification in single-channel oxidation ditches at one underloaded and one overloaded facility; nitrogen was removed and oxygen requirements were reduced. Results and theoretical considerations indicated that denitrification occurred continuously in anoxic microzones inside the floc. No anoxic zones were detected at one facility. Operation was relatively simple; primary control parameters were oxygen transfer rate and the average DO concentration (0.1 to 0.5 mg/L).
