Abstract

This paper discusses the development of a modified ASM1 model to better describe the overall removal of organic substrate from the high-rate activated sludge (HRAS) processes. This model will include process mechanisms for flocculation of particulate and colloidal substrate, hydrolysis, and production of extracellular polymeric substances (EPS). Consideration has also been given to the intracellular storage of soluble biodegradable substrate, but that is not the focus of this paper. The model framework presented in this paper is preliminary and just shows one approach that our team is evaluating. Future research efforts will evaluate different modeling alternatives including a single soluble biodegradable substrate model, incorporation of flocculation and adsorption kinetics for particulate substrate and EPS production kinetics as a separate process among others.
