Abstract

This paper presents a heat transfer model for equalization, activated sludge, and trickling filter unit processes that can be used to assess the effect of operating temperature on unit process selection, materials of construction selection, and heat retention and cooling requirements. In developing this model, the individual variables that affect the operating temperature of biological systems were first identified. Mathematical relationships were then developed to described system behavior, based on conservation laws and rate equations. The heat transfer models were then used to develop a temperature profile of the two alternative WWTP configurations.
