“…Thus, future studies should focus on the enrichment of ANAMMOX bacteria. Applicable strategies may include (i) using biocarriers to form attached ANAMMOX biofilm with a prolonged sludge residence time and eliminating the loss of biomass from effluent and (ii) using some adsorbents such as biochar- or granular-activated carbon to enhance the concentration of nitrogen on the surface of the biofilm for ANAMMOX bacteria to utilize …”

“…Applicable strategies may include (i) using biocarriers to form attached ANAMMOX biofilm with a prolonged sludge residence time and eliminating the loss of biomass from effluent 62 and (ii) using some adsorbents such as biochar-or granular-activated carbon to enhance the concentration of nitrogen on the surface of the biofilm for ANAMMOX bacteria to utilize. 63 Indeed, the ultimate goal in designing and establishing an energy-autarkic municipal WWTP would be to weaken its dependence on external inputs of energy, rather than solely to enable wastewater to be purified. In the proposed energy balance cases, further consideration should also be given to the CEPT-ANAMMOX system with regard to the extra chemical dosing costs and the decreases in the digestibility of sludge.…”

To reduce operational costs and carbon footprints, it is highly desirable to achieve energy neutrality in municipal wastewater treatment plants (WWTPs). We reviewed more than 100 nitrification/denitrification (N/DN)- and anaerobic ammonia oxidation (ANAMMOX)-based wastewater treatment systems. The energy consumption performance of N/DN systems ranged from 0.3 to 4 kWh/kg of COD and from 5 to 15 kWh/kg of N, while those of ANAMMOX-based systems ranged from 1 to 5 kWh/kg of COD and from 0.5 to 1.5 kWh/kg of N. According to an energy balance analysis of typical domestic wastewater (COD = 500 mg/L; TN = 50 mg/L) treatment, the conventional N/DN process consumes an average of 0.5 kWh/m3 (1.78 MJ/m3) more energy than the amount recovered from the digestion and incineration of its sludge. However, if wastewater is pretreated using a chemically enhanced primary treatment or anaerobic treatment (AT), subsequent ANAMMOX-based wastewater treatment systems may realize WWTP energy autarky or even electricity outputs of ≤0.17 kWh/m3. In such a nexus of energy recovery, the biogas generation from the AT or the digestion of sludge would be a more effective way to recover energy than the incineration of dewatered digestates. The combination of early stage COD capture and ANAMMOX is a promising approach to achieving sustainable energy performance in future WWTPs.

“…The typical doubling times are approximately 15–30 days ( Joss et al, 2009 ; Li et al, 2018 ). Generally, the start-up time of an AnAOB bioreactor exceeds 200 days ( Ge et al, 2008 ; Yu et al, 2013 ; Adams et al, 2020 ), and the start-up time even exceeds a pond breeding cycle. (2) The discharge time of pond aquaculture tailwater is relatively concentrated, and the one-time drainage is large, which may require large-scale water treatment reactors, but these facilities are idle for most of the time, and the enriched AOA or AnAOB biofilm needs long-term maintenance.…”

The excessive ammonia produced in pond aquaculture processes cannot be ignored. In this review, we present the distribution and diversity of ammonia-oxidizing archaea (AOA) and anaerobic ammonia-oxidizing bacteria (AnAOB) in the pond environment. Combined with environmental conditions, we analyze the advantages of AOA and AnAOB in aquaculture water treatment and discuss the current situation of pond water treatment engineering involving these microbes. AOA and AnAOB play an important role in the nitrogen removal process of aquaculture pond water, especially in seasonal low temperatures and anoxic sediment layers. Finally, we prospect the application of bioreactors to purify pond aquaculture water using AOA and AnAOB, in autotrophic nitrogen removal, which can reduce the production of greenhouse gases (such as nitrous oxide) and is conducive to the development of environmentally sustainable pond aquaculture.
