Screenshot of ASM1-SBR Spreadsheet


The ASM1-SBR spreadsheet was developed by Water Works Engineers as a means of modeling the performance and oxygen requirements over a single cycle of an SBR. The spreadsheet is based on the IWA Activated Sludge Model 1 and models the dynamic performance of reactor using 15 time steps. For each time step, the user specifies a volume of wastewater fed and the oxygen concentration maintained during that step.
