Water Recycling and Sanitation

So what are some ways we use water? Less than 1% of the water on Earth is fresh water that people can use for these purposes. Where does that water go? How does it come back to us clean? How can we conserve water at home?

Most water treatments have a substance added to the water to make certain kinds of particles in the water sink to the bottom. Then filtering systems are used to clean out the remaining purities. Here was the experiment.

I shaved a bar of soap with a cheese grater. We poured soap into two glasses of water and mixed it up. To one glass we added table salt. To the other we added Epsom Salt. Again we mixed them up. Then we used two new glasses with filters to filter the water. The Epsom Salted soap water came out looking clear. The Table Salt Soap Water was cloudy. Same glasses same filters same soapy water, different substance added.
