It's No Myth, Just Call Us Lith: Fresh. Clean. Pure.

Abstract
    We used water-oil separation to separate the oil from the water. We also used sand filtration to get rid of the solid particles, allowing the liquid to pass through. This makes the liquid less foggy. The sand trapped the solid particles. Finally, we used charcoal adsorption to completely clear up the water, permitting usage. Overall, this was a successful filtration process.

Procedure Overview
      By accident, we poured the foul water into the cylinder, but then put it back and waited one minute. After dropping several drops of distilled water, we realized water went to the bottom because it's less dense. The volume after oil-water separation was 96 ml. We then got a styrofoam cup and poked holes on the bottom using a paper clip. We put 1 cm gravel, 2 cm sand, and 1 more cm of gravel on top of that. We used a ruler to make sure it was exactly measured to 1 and 2 cm. We then put distilled water in the cup to moisten the gravel and sand. The holes that we made were large enough for the water to drain. Next, we poured 95 ml of the sample through the cup, completely changing the appearance of the water. We had to make sure that we tightened the ring on the ring stand properly. We folded the paper and moistened it slightly before putting it into the funnel. We poured partially distilled water into the charcoal. This ended up looking like black coffee. We then swirled the mixture, and put it into the funnel, making sure that the liquid level was below the top of the paper so that it does not leek out. We were shocked at how this dirty water changed into pure water. We observed that the dirty water slowly turned into these drops of pure water. Therefore, the process took a while. We later cleaned up all of the materials, and put them back where they belong.



                                                   Materials/ Equipment used:
                              -Foul Water
                              -Distilled Water
                              -Graduated Cylinder
                              -Pipet
                              -Funnel
                              -Paper Clip
                              -Sand
                              -Gravel
                              -Ruler


Result
      In result, we discovered that the water is pure enough for hand washing, but it is unknown to us if it is drinkable. Successfully, 86% was recovered as purified water from the original foul water. We wondered what is more important: water pollution or a lack of water. We realized that a lack of water is more critical because through this process, polluted water could be purified and used for many different tasks or uses. In the distillation process, we removed the salt from the water. Through the electricity test, we saw that the filtered water lit up the light bulb because it still had salt in it. The aggregated data showed that some groups' results were higher, while other groups had lower numbers. This proved that it is very difficult for all groups to have the same exact measurements or amount of water, sand, gravel, and etc.



                                                 Started from the foul now we're clear.
