Anammox Process

Release of nitrate and ammonia rich wastewaters into the natural waters promotes eutrophication, aquatic toxicity and deterioration in water quality. Anaerobic Ammonium Oxidation (ANAMMOX) process is an advanced biological nitrogen removal alternative to traditional nitrification – denitrification, which removes ammonia using nitrite as the electron acceptor without oxygen. The feasibility to enrich ANAMMOX bacteria from anaerobic seed culture to start up an Anaerobic Membrane Bioreactor (An MBR) for N – removal is reported in this paper. The seed culture used was anaerobic digester sludge collected from a Sewage Treatment Plant (STP) in Chennai. Stabilization performance of An MBR is reported for a period of 250 days, for the presence of ANAMMOX bacteria and its sustained activity in terms of Nitrogen transformations to Ammonia, Nitrite and Nitrate along with Hydrazine and Hydroxylamine.

Anammox Process

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 NH4+-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 (N2O) to atmosphere. Besides, NH4+-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 NH4+-N by adopting ANAMMOX process in AnMBR. The AnMBR was optimized for Nitrogen Loading Rate (NLR) varying from 0.025 to 5 kg NH4+-N/ m3/ d with hydraulic retention time (HRT) ranging from 1 to 3 d. NH4+-N removal efficacy of 85.13 ± 9.67% with the mean nitrogen removal rate (NRR) of 5.54 ± 0.63 kg NH4+-N/ m3/ d was achieved with nitrogen loading rate (NLR) of 6.51 ± 0.20 kg NH4+- N/ m3/ d at 1.5 d HRT. The nitrogen transformation intermediates in the form of hydrazine (N2H4) and hydroxylamine (NH2OH) were 0.008 ± 0.005 mg/L and 0.006 ± 0.001 mg/L, respectively, indicating co-existence of aerobic ammonia oxidizers (AOB) and ANAMMOX. The free ammonia (NH3) and free nitrous acid (HNO2) concentrations were 26.61 ± 16.54 mg/L and (1.66 ± 0.95) x 10-5 mg/L, preventing NO2--N oxidation to NO3--N enabling sustained NH4+- N removal.

Anammox Process

There are certain well-known methods of diminishing concentrations of nitrogen compounds, but they are ineffective in case of nitrogen-rich wastewater with a low content of biodegradable carbon. Partial nitritation followed by anaerobic ammonium oxidation (Anammox) process appear to be an excellent alternative for traditional nitrification and denitrification. This paper presents the feasibility of successful start-up of Anammox process in a laboratory-scale membrane bioreactor (MBR). It was shown that the combination of membrane technology and Anammox process allowed to create a new highly efficient and compact system for nitrogen removal. It was possible to achieve average nitrogen removal efficiency equal to 76.7 ± 8.3%. It was shown that the start-up period of 6 months was needed to obtain high nitrogen removal efficiency. The applied biochemical model of the Anammox process was based on the state-of-the-art Activated Sludge Model No.1 (ASM 1) which was modified for accounting activity of autotrophs (nitrite-oxidising bacteria and nitrateoxidising bacteria) and anammox bacteria. In order to increase the predictive power of the simulation selected parameters of the model were adjusted during model calibration. Readjustment of the model parameters based on the critically evaluated data of the reactor resulted in a satisfactory match between the model predictions and the actual observations.
