Dirty Water Problem
Aim
I want to investigate how to filter dirty water and make it safe to drink.
Equipment
- dirty contaminated water
- 4x funnels
- stand
- 4x clamps
- pebbles
- sand
- cotton
- charcoal
- paper towel
- Bunsen Burner
- fitler paper
Method
1. Set up the funnels in a line on the stand using clamp to hold them in place.
2. In the top funnel, put a small wad of cotton and then fill with small pebbles.
3. In the middle funnel put a small wad of cotton and then fill with sand.
4. In the bottom funnel put a small wad of cotton and then fill with charcoal.
5. Place a cup under the bottom funnel to catch the water.
6. Pour the dirty water into the top funnel, be careful not to overfill the funnel.
7. Boil the filtrate (filtered water) for 2 minutes and let cool.
Results
our water was not boiled enough because we ran out of time, before we boiled the water it looked very brown and dark
dissclusion
The pebble filter was able to filter out all the big items like twigs, leaves, bark debris.
The sand filter filtered the small debris like the dissolved mud.
The charcoal filter was able to remove most of the "cloudiness".
I did end up using a 4th funnel where I used coffee filter paper. The filtrate was relatively clear.
Conclusion
This was an effective way of filtering although by the time the water had gotten to the last filter, the water was only dribbling through.
