“…Besides, there was also a clear color change of the culture in vials B and C from dark yellow to pale yellow when the tested period was over. This phenomenon was consistent with the previous report about the change of anammox biofilm color when suffered serious inhibition (23). In addition, the culture weight in vial A specially showed a slight decrease after 9 weeks' incubation.…”

“…Further, oxygen demand is reduced as the ammonium is only required to be nitrified to nitrite instead of nitrate. As a result, anammox bacterial biomass yield is very low, creating a small amount of excess sludge production and thus lower operational costs [37,38]. Overall, the anammox process can reduce oxygen and exogenous carbon source demand by 64% and 100%, respectively, while reducing sludge production by 80-90% as compared to conventional WWTP nitrogen removal processes [39].…”

Water quality in San Francisco Bay has been adversely affected by nitrogen loading from wastewater treatment plants (WWTPs) discharging around the periphery of the Bay. While there is documented use of zeolites and anammox bacteria in removing ammonia and possibly nitrate during wastewater treatment, there is little information available about the combined process. Though relatively large, zeolite beds have a finite ammonium adsorption potential and require periodic re-generation depending on the wastewater nitrogen loading. Use of anammox bacteria reactors for wastewater treatment have shown that ammonium (and to some degree, nitrate) can be successfully removed from the wastewater, but the reactors require careful attention to loading rates and internal redox conditions. Generally, their application has been limited to treatment of high-ammonia strength wastewater at relatively warm temperatures. Moreover, few studies are available describing commercial or full-scale application of these reactors. We briefly review the literature considering use of zeolites or anammox bacteria in wastewater treatment to set the stage for description of an integrated zeolite-anammox process used to remove both ammonium and nitrate without substrate regeneration from mainstream WWTP effluent or anaerobic digester filtrate at ambient temperatures.

“…However, it mainly stayed in the range of 83-96% despite the constantly decreasing influent nitrite concentration ( o0:5 g NO À 2 -N/m 3 for the 100% RW ratio). This might be explained by the active presence of heterotrophic bacteria, which have been shown to be active even without addition of an external COD source (van de Graaf et al, 1996;Wyffels et al, 2004;Ni et al, 2012), as well as of ammonium and nitrite oxidizers. To fully clarify this phenomena further research is required.…”

“…The ANAMMOX bacteria accounted for 45% of the sample total living population, while the nitrite oxidizers and ammonium oxidizers accounted for the 10% and 9%, respectively (see appendix B). For additional information regarding the microbial population in an ANAMMOX reactor the reader is directed to the work of Dapena-Mora et al (2004), Ni et al (2012) and Tao et al (2012).…”
