Implementation of aeration control strategies and nitrate-based internal mixed liquor recycle control employing in-situ sensors and feedback PID controllers in an integrated fixed-fdm activated sludge wastewater treatment facility

摘要

Utilize in-situ sensors and feedback PID controllers to optimize overall carbon usage and total inorganic nitrogen removal by implementing ammonia based aeration control, ammonia vs nitrate control, and nitrate based internal mixed liquor control in an integrated fixed-film activated sludge wastewater treatment facility.
