“…In addition, washout of biomass due to the production of N 2 gas is another issue of anammox processes (Chen et al, 2010;Dapena-Mora et al, 2004;Strous et al, 1998). In order to efficiently initiate anammox process, effective start-up and operational methods must be sought.…”

“…HNO 2 can inhibit NOB more than AOB at concentrations of HNO 2 between 0.22 to 2.8 mg/L [18]. At high NH 3 concentrations, AOB compete over NOB leading to AOB enrichment in the system, as noticed in AnMBR [28]. N 2 H 4 was reported to be continuously generated from NH 4 + -N and NH 2 OH through NO and eventually oxidized to N 2 [12].…”

Anaerobic Membrane Bioreactor (AnMBR) is an innovative high cell density system having complete biomass retention, high reactor loading and low sludge production and suitable for developing slow growing autotrophic bacterial cultures such as ANAMMOX. The Anaerobic Ammonium Oxidation (ANAMMOX) process is an advanced biological nitrogen removal removes ammonia using nitrite as the electron acceptor without oxygen. The NH 4 + -N in the landfill leachate that is formed due to the release of nitrogen from municipal solid waste (MSW), when discharged untreated, into the surface water can result in eutrophication, aquatic toxicity and emissions of nitrous oxide (N 2 O) to atmosphere. Besides, NH 4 + -N accumulation in landfills poses long term pollution issue with significant interference during post closure thereby requiring its removal prior to ultimate disposal into inland surface waters. The main objective of this study was to investigate the feasibility and treatment efficiency of treating landfill leachate (to check) for removing NH

“…As for Anammox granules, the settling velocities of 73-88 m/h were observed in a UASB reactor [8], which were a little higher than anaerobic granular sludge. Chen et al [26] reported that Anammox granular sludge with a poor settling ability could lead to unstable operation in the Anammox systems. Some other characteristics, such as roundness, sphericity and mass shape factors, can also influence the settling velocity of Anammox granules.…”

Abstract-Anaerobic ammonium oxidation (Anammox), which is assumed to be an appropriate process for the treatment of nitrogen-rich wastewater, is a promising and novel biological nitrogen removal process with attractive application prospects. However, the drawback of this cost-effective process is the low growth rate of Anammox bacteria. So the Anammox process are often operated at a long solids retention time (SRT) in order to cultivate biomass successfully. The granulation of Anammox biomass offers an effective strategy to retain the biomass in Anammox reactors compared with other formation of sludge. This paper reviewed the up-to-date research progress, the property, the cultivation, as well as the application of Anammox granular sludge worldwide.
