McHarg, W H

In Part 1 a mathematical model was presented with which steady-state operating parameters could be calculated for aerobic biological systems that treat wastewater. The article used the model to determine the oxygen demand of the incoming wastewater, the flowrates into and out of the system and the rate at which sludge is recycled from the clarifier to the aeration basin. In addition to the four equations in four unknowns given in Part 1, the proposed model includes several other calculations. It can determine the oxygen required in the system and assist in graphical analysis of the clarifier. These uses are illustrated.
