Intro
Our group researched for many weeks on what is the best object for water purification, we thought the ocean takes up or just most of the earths water, 71% of the earth is ocean water we thought how can we extract the salts and wastes out of the water to make it drinkable. We did some research and found " Water desalination ".

Conclusion
The experiment was successful in that it achieved its purpose which was to build a platform for testing of water purification from diffrent materials. we found the best combination being courser materials at the top and finer materials at the bottom as the last stage of the filtering process. |
