heal.abstract	Two approaches based on new process development and biological nitrogen transformation were investigated in a bench study for removing nitrogen as N2 gas from poultry waste while stabilizing the wastes. The process, known as ""Anammox"", was explored in batch anaerobic culture using serum bottles. The Anammox process involves the use of nitrite as an electron acceptor in the bacterially mediated oxidation of ammonia to yield N2. Studies are described wherein nitrite was added to poultry waste and the effects on ammonium levels were monitored. About 13-22% ammonium removal was observed with the inoculation of returned activated sludge, and the total ammonium reduction was not proportional to the reduction of nitrite, thereby suggesting that Anammox was less competitive under the conditions in our studies. The addition of nitrite and nitrate was not inhibitory to the process based on gas generation and COD reduction. The classical nitrogen removal process of nitrification followed with denitrification offers a more reliable basis for nitrogen removal from poultry wastes. © 2002 Elsevier Science Ltd.
