Sample Water Purification Systems
Water purification systems provide clean drinking water.
There are two methods to clean water that you can pursue in this lesson. Distillation is a process for purifying water in which the water is first evaporated and then condensed and collected. Filtration is a process for purifying water in which the water is passed through a filter.
