Abstract: During our procedure we filtered water in three ways: oil-water separation, sand filtration, charcoal adsorption and filtration. Our group was successful in that we were able to filter enough foul water to a point where it could be used to wash our hands.

Procedure:

       1. Make a data table

       2.  Get 100 mL of foul water

              3. Fill out the first row of data in the chart

       4. Add oil to the water

       5.Let the sample to sit for 1 minute causing to the oil to rise to the top

       6. Remove the oil

      7. Add distilled water to the remove oil

      8. Fill out the second row of data

      9. Dispose of the liquid

      10. Poke holes in the bottom of the disposable cup

      11. Add 1 cm of gravel, 2 cm of sand, 1 cm of gravel

      12.  Gently pour the sample into the cup

      13 Catch the filtrate in a beaker as it pours through

      14. Dispose of the sand and gravel

      15. Place a moist folded piece of paper into the funnel

      16. Place the funnel in a clay triangle supported by a ring with a beaker underneath

       17.  Place one teaspoons of charcoal into the flask, pour the water, then stir

      18. Gently pour the liquid through the paper allowing it to filter through

19. If your filtrate is dark then repeat step 18

20. Record your results

21.  Dispose of the charcoal

Results

The water that we filtered had a salt in it because salt electrically charges a light bulb. From Dr. Forman's demonstration we learned that there are invisible particles in our water, and we did not create pure water.

1. Percent Recovery: 82%

2.  We lost 18mL of foul water

3. We lost 18% of foul water
