To provide the necessary nitrite for Anaerobic Ammonium Oxidation (ANAMMOX) process, effect of accumulation in partial sulfide autotrophic denitrification (PSAD) process was investigated using an SBR reactor. The results revealed that effectiveness nitrate removal unsatisfactory when S/N ratio (mol/mol) fell below 0.6. optimal conditions and were achieved within range 0.7-0.8, resulting average Nitrate Removal Efficiency (NRE) 95.84%±4.89% a Nitrite Accumulation Rate (NAR) 75.31%±6.61%,...
Nitrite-oxidizing bacteria (NOB) are crucial to nitrification and nitrogen elimination in wastewater treatment. Mass reports exist on the links between NOB other microorganisms, for instance, ammonia-oxidizing (AOB). However, a few studies enrichment characterisation of under high dissolved oxygen (DO) conditions. In this study, was designed be enriched individually DO conditions continuous aeration sequencing batch reactor (SBR), kinetic evaluated. The analysis revealed that average NO2--N...
A continuous stirred tank reactor (CSTR) was utilized in this study to enrich and cultivate anaerobic ammonia oxidation process (ANAMMOX) granular sludge by gradually decreasing its pH, investigate the effects of different concentrations ferrous ions (Fe2+) on activity ANAMMOX cultivated under biased acidic conditions. The final nitrogen removal deteriorated at pH 6.30–6.50 after 220 days operation, but favorable 6.50–7.00. This indicates that a slightly environment (pH = 6.50–7.00) promotes...
is a common genus of nitrite-oxidising bacteria (NOB) found in wastewater treatment plants (WWTPs). To identify the key factors influencing composition NOB communities, research was conducted using both sequencing batch reactor (SBR) and continuous flow under different conditions. High-throughput 16S rRNA gene revealed that
Under high DO at about 1.5-2.5 mg·L-1 and environmental temperatures (15-20 ℃) conditions, the NOB was entirely washed out, partial nitrification (PN) successfully achieved in 180 days. The sludge first enriched for 37 days, kinetic parameters of AOB were determined. substrate affinity coefficient 13.38±1.48 mg·L-1; FA inhibition 3.18±0.60 half-saturation constant 1.22±0.22 0.23±0.03 respectively. It contrary to conventional studies, stronger than that this study. Therefore, it is not...
