Excellent anammox performance driven by stable partial denitrification when encountering seasonal decreasing temperature

Effects of carbon diversion to primary sludge production on thermal hydrolysis pretreatment-enhanced anaerobic digestion

“…To our knowledge, PDNA is the only anammox-based technology applicable in the mainstream wastewater treatment in temperate zones. 35 At the same time, the energy cost for aeration can also be saved because only a portion of influent ammonia needs to be oxidized into nitrate. 34 Hence, innovative technologies such as PDNA may work in synergy with carbon diversion to achieve sustainable wastewater treatment when it comes to infrastructure upgrading.…”

Recent developments and prospects for engineering first-row transition metal-based catalysts for electrocatalytic NOx− reduction to ammonia

“…In nature, anammox bacteria have been proved to exploit Fe 0 / Fe 2+ as electron donors for the denitrification of NO 3 − and NO 2 − . 75 In addition, the presence of Fe as the active site in nitrogenase enzymes has also promoted considerable exploration of Fe-based electrocatalysts with abundance on Earth. 44 The performances of currently developed Fe-based electrocatalysts are listed in Table 2.…”

Insights into the Responses of the Partial Denitrification Process to Elevated Perfluorooctanoic Acid Stress: Performance, EPS Characteristic and Microbial Community

“…Recent advances in the stability of the PD process have demonstrated that the accumulation of NO 2 − -N was subject to environmental factors. For instance, under a low temperature of 20 • C, the biofilms showed a significantly higher NO 2 − -N accumulation of 74.7% than that of 59.9% under a high temperature of 30 • C [7]. Moreover, Gao et al [8] found that triclosan inhibited the NO 2 − -N accumulation as the triclosan dosage increased from 1 mg/L to 5 mg/L.…”
