Steps
- Design a multi-stage filter with sand, activated carbon, and a settling step.
- Build the filter stages in clear containers connected with tubing.
- Mix a test greywater with a measured amount of soap and fine dirt.
- Pump water through and log turbidity before and after each stage, plus flow rate.
- Calculate removal at each stage and find which stage does the most work.
- Document the system and results for your portfolio.
What to photograph for your portfolio
- Filter build
- before/after turbidity
