Technical Bulletin No. 0477: Modification of the NCASI ASB Treatment Plant Model for Simulating Conditions When Basin Temperatures Exceed 35 F

As use of the NCASI wastewater treatment plant mathematical models increased, refinements were necessary to properly simulate systems with characteristics beyond the original scope of the models. One such characteristic was the occurrence of temperature conditions above 35°C within the aeration basin. In this bulletin, four alternative models relating BOD removal rate with temperatures exceeding 35°C were presented.
