Activated Sludge Model 1 for SBRs
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. This spreadsheet is open source shareware that we are offering to the community as a collaborative product; please read the licensing terms embedded in the spreadsheet and only use it if you agree to them. Please send us any suggested improvements, comments, or enhancements so that we may share them with others.
