TL;DR: In this paper, the authors study how and to what extent effluent BOD 5 is related to influent BOD 1 and flow in an activated sludge process. But, the analysis is based on data collected hourly over a 2-week period at a Wisconsin sewage treatment plant and does not need flow as a predictor variable.
