Bench and Full Scale Evaluation of an Alternative Sidestream Bioaugmentation Process

Modeling, Instrumentation, Automation, and Optimization of Wastewater Treatment Facilities

“…Blackburne et al (2007a) presented a method for estimating nitrifier maximum growth rate and yield by measuring the rate of carbon dioxide uptake and additional rates of oxygen uptake and ammonia (or nitrite) use, using batch tests in a combined titrimetric and offgas analyzer with enriched Nitrobacter and Nitrosomonas cultures and an activated sludge sample. Ramalingam et al (2007) modified the Biowin TM model to include free nitrous acid inhibition and modeled bench-and full-scale nitritation associated with a sidestream nitrifier augmentation process. The full-scale operating conditions raised process stability and greenhouse gas emission potential concerns.…”
