“…To this end, completely autotrophic nitrogen removal over nitrite (CANON), SHARON-Anammox, denitrifying ammonium oxidation (DEAMOX) have been studied with dilute wastewaters or sewage (Nozhevnikova et al 2012;Schmidt et al 2003). These studies showed the importance of DO control for nitrite formation so that complete nitrogen removal could be further carried out by Anammox.…”

The nitrogen (N) cycle, one of the most important biospheres on Earth, consists of complex interactions among various nitrogen compounds. Anaerobic ammonium oxidation (Anammox) is a N-transformation pathway that was discovered in the 1990s. The metabolism of Anammox bacteria relies on the oxidation of ammonium for energy using nitrite as the electron acceptor to form nitrogen gas. Due to its chemolithoautotrophic nature, lack of requirement for aeration and organic carbon (C), as well as the high efficiency of N-compounds' conversion to nitrogen gas, Anammox holds an attractive potential for N-removal from wastewaters, especially for those with a low "carbon/nitrogen (C/N)" ratio. This chapter presents the up-to-date information of Anammox bacteria genera and their versatile metabolic pathways found by a number of advanced molecular techniques, and also gives a brief summary on their potential nitrogen sources of cell synthesis through microbial thermodynamic calculations. Considering its applicability for nitrogen removal from wastewaters (both for highstrength and dilute strength), the effect of solid retention time on the nitrogen removal efficiency and inhibitors on Anammox process are discussed. Moreover, its possible involvement in syntrophy for sulfate reduction and ammonium oxidation triggers scientists to wonder if it plays a significant role in the global nitrogen-sulfur cycle.

“…The use of solid sup ports makes it possible to solve the problem of biomass washout from the reactor; metallic and polymeric nets, balls of pored material, pored polyethylene plates, granules of polyethylene glycol, glass balls, and sand particles can be used for this purpose in anam mox reactors. The most efficient was a reactor with polymeric brush carriers on which the number of anammox bacteria reached 1.7 × 10 7 cells/mL on the 21st day of work [11,12].…”

This review summarizes the information concerning the following applications of microbial bio films in biotechnology: the biodegradation of organic substances and other contaminants during wastewater treatment, biosynthesis, and biocatalysis. The main types of reactors for implementing biotechnical processes based on microbial biofilms are discussed. The advantages and drawbacks of biocatalysts in the form of microbial biofilms for the biotransformation of organic substances are examined.

“…The realization of anammox ensures nitrogen removal when the content of organic substances is low or when they are absent. The technology developed by ZAO ECOS Company is a full scale realization of the combination of the den itrification and anammox processes (DEAMOX) [5] and is referred to as BC DEAMOX [12].…”

“…Taking into account the period of search for the optimum conditions for the function ing of the conjugate aerobic nitrifying reactor (SHARON system), it took about four years to start up the world's first full scale anammox reactor [10]. By now, technological anammox based schemes of treat ment of high nitrogen wastewater have been devel oped, and a pilot and several full scale treatment plants have been put into operation [11,12].…”

This work studied the formation of molecular nitrogen by the microbial population of immobi lized activated sludge of the domestic wastewater treatment plants (WWTP) that employ the technology developed by ZAO ECOS Company. The technology includes physicochemical water pretreatment and treated water recycling. A hard flexible fibrous brush carrier is used for the immobilization of microorganisms. The presence of both aerobic and anaerobic microorganisms and functioning of the methanogenic microbial community was shown in the biofilms developing on the carrier fibers and in suspended sludge. The high effi ciency of nitrogen removal at a low C/N ratio was established to be due to the conjugated nitrification, den itrification, and anammox processes, whose functioning was demonstrated by laboratory cultivation methods and by studying the processes in batch and continuous reactors. Fluorescence in situ hybridization with 16S rRNA targeted oligonucleotide probes (FISH) revealed bacteria belonging to the order Planctomycetales, particularly their anammox group. This work is the first evidence of the important role of the anammox pro cess in the combined system of physicochemical and biological treatment of weak wastewater (BC DEAMOX).
