Football Shaped Filter

 I designed a water filter with three layers of filtration. After we learned that we would not be able to make the filters at school, I had to adapt my design. I decided to cut two plastic bottles and put them together to make a double sided water filter. At first I wanted to make a filter that had more than one part.

Here was my original design. But when it got closer to the time of turning in the filter on time this became harder to make. On top of that I also didn't have the materials to make this design. This made it harder for me to think of a good idea for the project. Then I noticed that my brother had a lot of bottles that he made art with. So I decided that I would make a filter that on one side there was the top where to water would be filter. On the other side the water would go down into your cup so you could drink it that way

My filter is made from cutting two plastic bottles in half and attaching them. This is why it has a football shape. The water is filtered through activated charcoal, zeolite blend and polyester mesh fabric.












    Filter was made of:
    5 tsp of zeolite blend
  • 0.38 ounces of activated charcoal

  • Polyester fiber mesh bag
Container was made of:

Ziploc bag strip

Scotch tape

Packing tape
Plastic bottles

Here is what my water looked like before filtering, as you can see my water is very dirty and needs to be cleaned




Here was my filtering process, on the top there is the filter, when the water is poured from the top it will go trough the filter and down to the bottom so it will be ready to drink. The red line is suppose to help you measure how much water you should put in at a time so none of it leaks out. As you can see this here is the process


Here is my water post filtering, I then put in the water strip to test for the ph hardness and nitrate. When you compare it to the water post filtering you can see that there isn't as much pepper in the cup and the particles you can't really see as much where you can see them a lot easier before filtering

Action project 3-RBL

 

This is my storyboard, I did it off of SDG's 11 and 4, the idea is to show what education and cities look like now and is supposed to show what we could improve on after looking at these things.
