“…This decrease could be caused by differences in the conductivity and organic matter and salts content between the synthetic and real wastewaters. Nevertheless, the NLR achieved treating the reject water was very high compared with most of the bibliographic references of PN systems [5,9,26,27]. Moreover, the TNN/TAN ratio, which is the most important parameter for a subsequent anammox reactor, was stably maintained at 1.3±0.3, while the nitrate concentration in the effluent was always lower than 5 mg N L -1 .…”

“…Among the proposed treatments, biological processes are the most convenient from both economic and ecological points of view. Biological nitrogen removal of reject water can be performed by i) the classical nitrification -denitrification (full ammonium oxidation to nitrate followed by heterotrophic denitrification), ii) nitritation -denitritation (oxidation of ammonium to nitrite followed by nitrite denitrification), which has some advantages compared to the conventional process [2,3] and iii) partial nitritation (PN) -anammox which is the most novel process and ensures nitrogen removal through an autotrophic process [4,5]. As a pretreatment of the anammox reactor, the PN reactor has to achieve an effluent ratio of total nitrite nitrogen (TNN = NO 2 --N + N-HNO 2 ) / total ammonia nitrogen (TAN = One of the most common PN reactors for achieving the suitable influent for anammox is the SHARON process [4].…”

“…Occurrence of unionized NH 3 and HNO 2 is dependent on the pH and temperature in the biological system and leads to inhibition of NO 2 --N conversion [60]. Presence of NOB (Nitrite Oxidizing Bacteria) inhibition is evident when NH 3 concentration is above 0.1 mg/L [32,59,60].…”

ANAMMOX (Anaerobic ammonium oxidation) bacteria, leading proponent of autotrophic ammonia removal, requires dedicated enrichment and cultivation techniques due to its slow growth rate and low biomass yield. Sensitivity to inhibitory concentrations of NO 2 --N, O 2 etc., often present in industrial effluents makes ANAMMOX startup difficult to achieve. In this paper, significant parameters for ANAMMOX startup and development such as source of seed, type of reactors used, one and two stage ANAMMOX process, operational strategies and experimental conditions promoting long term enrichment, cultivation and quantitative analysis with biomass retention are discoursed in detail. Key chemical and molecular signatures including NO 2 --N, Alkalinity, O 2 , Polymerase chain reaction (PCR), Fluorescence in situ hybridization (FISH), Scanning electron microscopy (SEM), inhibitors and affinity factors for ANAMMOX activity are deliberated. Summary of state of the art on ANAMMOX enrichment, recommendations for future research with specific contributions of this paper to scientific community is brought out in conclusion. State of The

“…In most of the treatment systems using anammox, a two step system of nitritation-anammox is adopted (Hellinga et al, 1998;Van der Star et al, 2007;Yamamoto et al, 2008). We are developing a two step system of nitritation-anammox in a similar way.…”

In order to assess the stability of nitrogen removal systems utilizing anaerobic ammonium oxidation (anammox), it is necessary to study effects of influent dissolved oxygen (DO) on anammox activity since effluent from nitritation process feed to anammox process. In this study, the effects of influent DO on anammox bacteria entrapped in gel carriers were investigated using continuous feeding tests. The tests were performed in duplicate to confirm the reproducibility and anammox activities were evaluated under different DO concentration of 0 from 5 mg/L in influent. These results suggested that the DO concentration in influent to anammox reactor must be less than 2.5 mg/L. In addition, it was shown that the effect of influent DO on the anammox reaction is reversible because fallen anammox activity by influent DO of 5 mg/L recovered when the influent DO concentration was decreased to less than 1 mg/L.
