Development of a model for activated sludge aeration systems: Linking air supply, distribution, and demand. Proceedings WWTmod2016
Abstract: During the design of a wastewater treatment plant (WWTP), it is becoming industry practice for engineers to use simulation software to assist with process design. Aeration is one of the key components of the activated sludge process, and is one of the most important aspects of modelling wastewater treatment systems. A comprehensive dynamic aeration system model has been developed that captures both air supply and demand. The model includes sub-models for blowers, pipes and fittings, valves, and diffusers. Oxygen transfer within aeration tanks is also included as part of the overall model. The aeration system model allows engineers to analyze aeration systems as a whole to determine biological air requirements, blower performance, air distribution, control valve impacts, and controller design and tuning.
