Performance comparison between a two-reactor cascade and a single tank in an activated sludge wastewater treatment process
We investigate a model for the treatment of wastewater in the activated sludge process. The process is based on the aeration of wastewater with flocculating biological growth, followed by the separation of treated wastewater from biological growth. The biochemical model consists of two types of bacteria: sludge bacteria and sewage bacteria; and two types of ciliated protozoa: free-swimming ...

Ammonia-based aeration control with optimal SRT control: improved performance and lower energy consumption Proceedings ICA2017
Abstract: Ammonia-based aeration control (ABAC) is a cascade control concept for controlling total ammonia nitrogen (NHx-N) in the activated sludge process. Its main goals are to tailor the aeration intensity to the NHx-N loading and to maintain consistent nitrification, which meets effluent limits but minimizes energy consumption and improves nutrient removal. One limitation to ABAC is that the ...
