Originally named Transportable Water Bowl(Trawabo),
How it works:
All from scratchEverything we used for our filter was all homemade. The materials we only ordered was the spigot and spray paint. We used 3 home depot buckets, the top one consist of holding the dirty water, the middle has all the minerals in it and the third bucket collects all the clean water.
What were the minerals used in the 2nd layer?We used over 5. types of minerals: Activated carbon, activated charcoal, clean gravel, natural sand. They are listed from top to bottom. The point of the gravel and sand is to give the water a clearer look, our earlier model was displaying the water with a dark tinted color from the charcoal. Sand and gravel helps clear that color out.

Safe to drink?Our water we've filtered out has gotten 2.0 on the turbiditiy test which detects how clear the water. For that, we put our filtered water into a test tube into a machine that shoots light from the left to the right to see how transparent it is. We've gotten good ph results around flat 7 and we've been getting no sulfur detection in the water.
What can your product filter out?We had some several breakthroughs with our product, we first tried filtering soil water with our earlier models, after that worked, we expanded what we could filter as we were remodeling our product. By the final product, we're able to filter out mud water to clear water that is safe to drink. Though, after it is used several times, the minerals would have to be replaced.
