Recently, several novel and cost-effective biological nitrogen elimination processes have
been developed, including partial nitritation, nitrifier denitrification, anaerobic ammonium …

Over the past few years, new technologies for nitrogen removal have been developed
mainly because of the increasing financial costs of the traditional wastewater treatment …

Many countries strive to reduce the emissions of nitrogen compounds (ammonia, nitrate,
NOx) to the surface waters and the atmosphere. Since mainstream domestic wastewater …

The present-day wastewater treatment practices can be significantly improved through the
introduction of new microbial treatment technologies. Recently, several new processes for …

Anaerobic ammonium-oxidizing (anammox) bacteria convert ammonium to N 2 with nitrite
as the terminal electron acceptor in the absence of O 2. Nitritation–anammox bioreactors …

The microbiology and the feasibility of a new, single-stage, reactor for completely
autotrophic ammonia removal were investigated. The reactor was started anoxically after …

Many different aerobic and anaerobic biological processes and treatment schemes are
available for transforming organics and/or removing nitrogen from domestic wastewaters …

Anammox bacteria can perform dissimilatory nitrate reduction to ammonium (DNRA) with
nitrite as intermediate coupled to the oxidation of volatile fatty acids (VFA). Batch tests with …

The anaerobic ammonium oxidation (Anammox) process, discovered 20 years ago, is, in
combination with partial nitritation, ideally suited to treat nitrogen rich waste water streams …

Discharge of nitrogenous components to water bodies can cause eutrophication,
deterioration of water quality, toxicity to aquatic life, and pose a potential hazard to human …
