What you'll need
- Software only - Excel, Ten States Standards (free), draw.io or AutoCAD student version
Steps
- Estimate average and peak design flow for 5,000 people.
- Set influent assumptions for BOD, TSS, and ammonia.
- Size the bar screen, grit chamber, and primary clarifier.
- Size the aeration tank using SRT and food-to-microorganism ratio, and estimate oxygen demand.
- Size the secondary clarifier and chlorine contact tank, then draw the process flow diagram.
- Compile a design summary and document it for your portfolio.
What to photograph for your portfolio
- Process flow diagram
- design summary table
- calculation pages
- plant layout sketch
