|The Water Filtration Process|
This demonstration is designed to demonstrate the procedures that municipal water plants use to purify water for drinking. Students will discover that water treatment plants typically clean water by taking it through the processes of aeration, coagulation, sedimentation, filtration, and disinfection. They also learn that water in lakes, rivers, and swamps often contains impurities that make it look and smell bad. The water may also contain bacteria and other microbiological organisms that can cause disease. Consequently, water from surface sources must be cleaned before it can be consumed by people.
