Enhancing nitrogen removal performance of anammox process after short-term pH and temperature shocks by coupling with iron-carbon micro-electrolysis

Exploring denitrification and anammox processes in the saturated zone of passively operated vegetated biofiltration systems

“…SM1A02 , the genus that has been suspected to be a novel anammox strain in a few recent studies, 5,58,59 was found in the media but at lower abundance levels (0.002% to 0.137%; Table 2). Comparing to its abundance level in the media at the end of the denitrification phase (week 9, Fig.…”

“…aSuspected anammox bacteria, as per ref. 5, 58 and 59. WSC – softwood chips, HWC – hardwood chips, MIX – MIX of 1 : 1 gravel and hardwood chips.…”

Ecological filter walls for efficient pollutant removal from urban surface water

“…studied that Pseudomonas showed superior heterotrophic nitrification aerobic denitrification (HNAD) ability in treating nitrogenous wastewater, with maximum removal efficiency of 10.0 and 8.9 mg L -1 h -1 for NH 4 + -N and NO 3 - -N [ 55 ]. Besides, the abundance of anaerobic ammonium oxidation (anammox) bacteria like SM 1 A 02 was 1.1% and 3.7% in the facultative and anoxic zone, respectively [ 56 , 57 ]. It was reported that SM 1 A 02 was found to be enriched in the anammox sludge [ 58 ].…”

Effects of alkalinity addition with different strategies on CANON process: Start‐up, performance, and microbial community

“…Simultaneously, 1.00 g of NH 4 + ‐N removed by the anammox process would produce 4.64 g of alkalinity. Thus, the CANON process requires additional alkalinity to neutralize excessive H + and maintain a suitable pH range (6.5–9.0) (Xie et al, 2021). Alkalinity is usually supplemented by the addition of NaHCO 3 or Na 2 CO 3 in CANON.…”
