Selection of carbon materials and modification methods in

01/10/2017 · In contrast to acid modification, modifying biomass char with steam had just a little influence on denitrification results in a way that the denitrification rate decreased with the temperature increase. The denitrification rate of S-4 (973 K) was 11%, S-5 (1023 K) was 5.5% and S-6 (1073 K) was only 2.0%, respectively.

Growth Yields in Bacterial Denitrification and Nitrate

01/03/2007 · Denitrification and nitrate ammonification are considered the highest-energy-yielding respiration systems in anoxic environments after oxygen has been consumed. The corresponding free energy changes are 7 and 35% lower than that of aerobic respiration, respectively.

Activated Sludge Biological Nutrient Removal Process

resulted in a growth of 7,806 lbs of biomass (at the yield of 0.65). • If 2% of the biomass is Phosphorus (2% is reduced from 3% to compensate for inerts in MLSS), 156 lbs of phosphorus are removed in the biosolids. • If the influent concentration is 5.5 mg/L TP, 367 lbs of P are received in the influent.
