	abstract = "A suspended growth deammonification process has been in full-scale operation for over two years in Austria. Three US utilities have embarked on piloting this process at two locations: New York City and Alexandria, Virginia. Deammonification is a two-part autotrophic reaction involving two distinct biomass populations. In the first step aerobic ammonia oxidizing bacteria (AOB) nitrify partially ammonia to produce nitrite. In the second step anaerobic ammonia oxidizing microorganisms (anammox) autotrophically denitrify these products to nitrogen gas. Alkalinity limitations and ammonia inhibition are used to control the production of near equimolar nitrite and ammonia, while limiting nitrite toxicity is key to facilitating autotrophic denitrification. The paper describes the parameters that are important to control single-sludge suspended growth deammonification and how the DEMON process uses pH to control the two key reactions, at the same time controlling residual nitrite levels to prevent nitrite toxicity.",
