Proof Of Concept
After we built our filter, we decided to test it for things that may be found in Ethiopian rainwater. Namely, a high acidity, and turbidity (how clear/dirty it is). Here are our findings:
Turbidity test:
Turbidity before filtration: 174.6 Turbidity after filtration: 7.2 |
PH test:
Acid rain before filtration: 4.5 (made with vinegar and water) Acid rain after filtration: 7.0 (neutral) |
