Activated Sludge Waste Water Treatment Calculations with Excel Formulas

Activated sludge waste water treatment calculations are made easy in U.S. or S.I. units with the Excel spreadsheets that can be downloaded through links in this article. The Excel formulas use parameters like biochemical oxygen demand (BOD), waste water flow rates, and total suspended solids concentrations to make activated sludge aeration tank design and operation calculations. There are activated sludge process flow diagrams and lists of parameters used in the design and operation calculations with both U.S. and S.I. units.
