Water filters🚰💧

A couple of weeks ago we started a water filtration unit. In the unit,  we build water filters and test them on contaminated water. Also, The rating system is one to five, five being the worst one being the very best so basically one means completely normal water. The first step was drawing the sketches. well, Melike drew the sketches the did I not mention that my group is Melike, Arav, and Rehma (ill put links to there blogs). Then we started building, the materials that we used for charcoal A net coffee filters and Sand & Gravel. The order was first a paper filter or at the bottom another paper filter sand and gravel then the net. Our first try was not a success it got rid of all the microbes and all the big particles but no color. It turns out that the charcoal had to be way more crushed then it’s actually was. we didn’t have any hammer or anything to crush it so we just had to deal with it. Then we built a second filter this one was to try to get rid of the color. Another problem with the first one was that the water slipped through the side because our bottle had a big dent in it. For this filter, we use the same tools but in a different order and more of the sand and gravel. The order was coffee filter charcoal tons of sand and gravel then a net. This filter removed some of the colors but barely made a dent. At the end of the project it turns out I love water filtration, and during this project, I’ve learned about a lot of water filtration products that I’m interested in trying. I also learned lots about water in other countries and how in some country they have to walk to dirty ponds to get water. In conclusion, I loved this project I love what it encourages I love the topic just a great project in my opinion.
