Design engineers in the wastewater sector face a critical choice when sizing facilities: rely on specialized, commercial simulation software or build proprietary, Excel-based calculation suites. While commercial simulators offer complex dynamic modeling, Microsoft Excel remains the industry benchmark for steady-state design calculations.
Developing or purchasing a robust Excel engineering template involves a one-time cost or development effort. There are no recurring annual subscription fees per seat. Key Modules to Include in Your WWTP Design Spreadsheet Dropdown selection boxes (Data Validation)
One of the most powerful applications of VBA in this field is the ability to implement sophisticated process models. The paper on the PKES simulator demonstrates how VBA can be used to build a comprehensive tool for wastewater treatment plants that integrates advanced mathematical models:
Does anyone have recommendations for high-quality — either free resources or paid tools — that you've found to be reliable and accurate for real-world design or academic projects?
