Abstract

Design criteria for nitrification and denitrification of high-strength nitrogenous wastes have been derived by pilot-scale experiments in two submerged filters in series. molasses proved to be a suitable carbon source in denitrification. It has been shown that oxygen is the rate limiting substrate in nitrification and that maximum denitrification rates can only be achieved at an influent COD/NO(x)-N ratio of approximately 5.
