  Abstract:  Natural nitrogen cycling is at present seriously disturbed by human activities. The main sources of nitrogen pollution are the industrial streams and municipal wastewater. The biotechnological treatment of such streams represents a viable alternative to the classic technologies of reducing the pollutants level released to the water, soil or atmosphere. In the present paper, the current knowledge on anaerobic ammonium oxidation (anammox), a recently described biological process, is discussed in regard to its biotechnological potential in nitrogen removal from wastewater. The process is compared to conventional biological nitrogen removal and the main modes of operation are also given. The paper is concluded with an overview of the state of the art of application on full scale.

Keywords: Anammox bacteria, dinitrogen gas, granular sludge reactor, nitrification-denitrification, autotrophic nitrogen removal, membrane-based system
