Solution Justification
The design of our water purifier allows us to purify any sample of water to a level that is safe for consumption. Our design contains materials that are easily accessible and inexpensive. The materials that are used in our water purifier are: sand, charcoal, coffee filters, a plastic bag, a rubber band, gravel, pebbles, a towel, and a water bottle.
The water bottle is used as the container for the purifier. The other materials are assembled inside. The plastic bag lines the inside of the water bottle. The plastic bag directs the flow of water to the different layers and out the bottom. The rocks and gravel are used to filter out any large particles that are in the water. The sand is also used as a filter, but for smaller particles contained in the water. The charcoal is used to kill the bacteria. The rubber band is used to hold the coffee filter that is positioned between the cap and the water bottle in place.
The coffee filters and towel have multiple purposes. They provide the ability to further remove particles from the water. In addition, they are both used to separate the different layers of materials in the water purifier. This prevents the layers from mixing together. Since these materials are all readily accessible, it lowers the cost and time of production. Also, the simple layered design makes it easy to assemble and dissemble.
The only equipment necessary is a box knife to cut the bottle and poke holes in the cap and a hot glue gun to set up the plastic bag on the inside. This further reduces the cost and time of production.
