Clean water was very important for health and daily life. Sometimes water looked cloudy because it contained small dirt particles. This cloudiness was called turbidity. In this project, we wanted to find out if desert plants like cactus and moringa seeds could help clean dirty water using a DIY 3D water filter. We built our filter using layers of gravel, pebbles, dried moringa seeds, dried cactus material, activated charcoal, and cotton. We prepared dirty water by mixing soil with water and measured its turbidity before filtration. Then, we poured the water through our filter several times and measured the turbidity after each pass. Our results showed that the dirty water had an average turbidity of 35.47 NTU, which meant it was very cloudy. After filtration, turbidity decreased each time the water passed through the filter. The sixth filtration pass showed the highest turbidity reduction at 82.54%, making it the most effective result. This meant the water became much clearer after repeated filtration. Our findings showed that cactus and moringa seeds, which grow naturally in Yuma, had strong potential as natural and low-cost materials for water filtration.

  1. The layout and overall methodology and creativity of this experiment is topnotch. Using different layers for the filtration systems and trials was very scientific. Great work!!!

  2. Congratulations on your amazing project, this is a very important topic and everyone did an outstanding job💕!!

  3. What an interesting way to filter water naturally and effectively.

    I congratulate you for showing and proving through scientific method that there continues to be natural resources that help stabilize our habitat; in this case water, something we can’t live without.

    Continue to expand your knowledge and understanding of science and nature and enjoy the depth of the discovery process.

  4. Great job!!! Your experiment was creative and shows how plants can help environmental problems. I’m really interested to see what other ideas and projects you come up with in the future.

  5. Fantastic work! Your project is creative, smart, and very important for helping people learn about clean water.

  6. You girls are amazing!!! All is possible! Amazing idea especially the way pollution is damaging our world. Keep science alive with your curiosity! Excited to see you grow and what the future holds for you. Mom and Dad are so proud of you Julie!! We Love you!!!
