Sidestream Deammonification Startup - Process Controls

Modeling, instrumentation, automation, and optimization of water resource recovery facilities (Review of 2018 Literature) DIRECT

“…Stable nitrogen removal was achieved, and aeration was minimized with intermittent aeration to maintain DO below 0.5 mg/L and ammonium-N above 5 mg/L. A sidestream treatment DEMON SBR process control strategy with on/off aeration to control pH was effective in suppressing NOBs (Yin, Chandran, Li, & Reck, 2018). Anammox and AOB populations were reduced during periods of poor centrate quality and reduced flocculent sludge waste due to competition from heterotrophs and NOBs but their microbial activities were higher and nitrogen removal was not reduced.…”
