The main issues with mainstream anammox application are loss of bacterial activity by low temperatures and a high organic content wastewater. We demonstrate novel switching method between sidestream wastewater flow was switched (reject water at >22°C) (municipal 16.5°C), so that the biomass growth could benefit from conditions. Real (biogas plant effluent) (≈1000 mg NH+ 4-N L−1) synthetic wastewater-like source) (≈100 4-N) were used for 20 L biofilm reactor feeding. highest total nitrogen...
Biological nutrient removal from wastewater to reach acceptable levels is needed protect water resources and avoid eutrophication. The start-up of an anaerobic ammonium oxidation (anammox) process scratch was investigated in a 20 L sequence batch reactor (SBR) inoculated with mixture aerobic sludge at 30 ± 0.5 °C hydraulic retention time (HRT) 2–3 days. use NH4Cl, NaNO2, reject as nitrogen sources created different salinity periods, which the anammox performance assessed: low (<0.2 g...
The nitritation–anaerobic ammonium oxidation (anammox) process was studied for the first time using an oxidation–reduction potential (ORP) decrease rate control in anammox sequencing batch reactor (SBR). SBR inoculated and fed with high-strength N-rich real reject wastewater (containing average of 740 mg NH4+-N/L) coming from a biogas plant. Start-up total nitrogen removal rates (TNRRs) 90 g N/[m3·day] (87 N/g VSS/day) achieved shortly at 25°C within 132-day operation period. However, during...
