“…This value is not fixed. Recently, the nitritation process was also successfully started up and maintained between 15 and 30 °C (Yamamoto et al, 2006). However, the system performance deteriorated dramatically below 15 °C, which agreed well with the theoretical value in Fig.3.…”

“…Furthermore, other factors such as operation mode, aeration pattern, reactor configurations and operating costs all should be considered comprehensively. For example, it was feasible to run the nitritation process at lower temperature (around 15 °C) with an extended SRT (Yamamoto et al, 2006). Besides, if the DO concentration was limited, the process would remain stable with SRT as long as 24 d (Pollice et al, 2002).…”

Abstract:The concept of anaerobic ammonium oxidation (ANAMMOX) is presently of great interest. The functional bacteria belonging to the Planctomycete phylum and their metabolism are investigated by microbiologists. Meanwhile, the ANAMMOX is equally valuable in treatment of ammonium-rich wastewaters. Related processes including partial nitritation-ANAMMOX and completely autotrophic nitrogen removal over nitrite (CANON) have been developed, and lab-scale experiments proved that both processes were quite feasible in engineering with appropriate control. Successful full-scale practice in the Netherlands will accelerate application of the process in future. This review introduces the microbiology and more focuses on application of the ANAMMOX process.

“…The partial nitrification process was successfully operated at room temperature as it has been previously observed by Yamamoto et al [17]. They reported that the nitrite production rate did not significantly decrease when the temperature remained above 20 °C, indicating that the partial nitrification at room temperature is possible using another kind of control as the pH.…”

The Anammox based processes are suitable for the treatment of wastewaters characterized by a low carbon to nitrogen (C/N) ratio. The application of the Anammox process requires the availability of an effluent with a NO 2 --N/NH 4 + -N ratio composition around 1 g·g -1 , which involves the necessity of a previous step where the partial nitrification is performed. In this step the inhibition of the nitrite oxidizing bacteria (NOB) is crucial. In the present work a combined partial nitrification-Anammox two units system operated at room temperature (20 ºC) has been tested for the nitrogen removal of pre-treated pig slurry. To achieve the successful partial nitrification and inhibit the NOB activity different ammonium/inorganic carbon (NH 4 + /IC) ratios were assayed from 1.19 to 0.82 g NH 4 + -N·g -1 HCO 3 -C. This procedure provoked a decrease of the pH value to 6.0 to regulate the inhibitory effect over ammonia oxidizing bacteria (AOB) caused by free ammonia (FA). Simultaneously the NOB experienced the inhibitory effect of free nitrous acid (FNA) which avoided the presence of nitrate in the effluent. The NH 4 + /IC ratio which allowed the obtaining of the desired effluent composition (50% of both ammonium and nitrite) was of 0.82±0.02 g NH 4 + -N g -1 HCO 3 --C. The Anammox reactor was fed with the effluent of the partial nitrification unit containing a NO 2 --N/ NH 4 + -N ratio of 1 g·g -1 where a nitrogen loading rate (NLR) of 0.1 g N·L -1 ·d -1 was efficiently removed.

In this paper, one partial nitritation system with biological selector (PNBS) was first evaluated in treating high-strength ammonia containing wastewater. Nitrite production rate (NPR) of 8.25 kg N m -3 d -1 was achieved with influent NH4-N concentration 2000 mg l -1 and HRT 3.2 h, which is, to our knowledge, the highest NPR to be treated successfully by an nitritation reactor. A genetic analysis of the organisms in the PNBS revealed an abundance of Nitrosomonas sp. ENI-11, uncultured bacterium clone: AnDHS-3, Nitrosomonas sp. ENI-11 and Nitrosomonas eutropha enriched in the PNBS reactor.
