On this page is a digital photo compilation of all the trials our group did. Although these trials accured multiple times using various volumes of foul water the general procudure was extremely consistent so that the lab procedure is repeatable and reproducible.
After observing the foul water we noticed the presence of oil in addition to sediment and odor. We then created a filter to mimic a river bed by pouring rocks, then sand into a styrophome cup.
We poked holes in the bottom of the cup to allow the foul water to drain through into a beaker, then poured the water in through a funnel with filter paper.
The process took a very long time so we used a ring stand to stabilize the funnel and we were then able to leave the experiment over night.
The result of this filtering process was mostly oil free, but very cloudy water. We hypothesised that this was because sediment was able to drain through the holes in the cups. We then filtered the water again through a funnel with filter paper. This resulted in clearer water that was odor and sediment free.
Next, we mixed the water with characoal and after stirring virorously for twenty seconds filtered it with filter paper into an erlenmeyer flask.
Finally our group achieved clear water. Our voume was relatively low but the water was odor, sediment and oil free.
We brainstormed some ideas for distilling the water using the materials we had on the island. Besides drawing sketches we modelled a few scenarios.
