Water Treatment Science

Clear water doesn't necessarily mean safe-to-drink water, but you definitely don't want to drink water that looks dirty, murky, or otherwise has things visibly floating in it. Water that is collected in water treatment plants, however, may be exactly like that in the beginning, turbid water full of floating particles that doesn't look like something you would want to drink.

At a water treatment facility, water goes through several processes to help "clean" the water. Common processes include coagulation and flocculation. Together these processes help get rid of particles in the water, which also helps clear the water.
