The water is disinfected to destroy or inactivate disease-causing organisms, such as viruses, bacte-ria, fungi, and protozoa. Chlorination is the most common disin-fection method, but other methods are also used. Next month, How Water Works will begin looking at the distribution process.

This process of water treatment comes before the main stages in the treatment of the water. The pre-chlorination also oxidizes taste- and odor-causing compounds. 3. Coagulation and Flocculation. After aeration, coagulation occurs to remove the fine particles (less than 1 µm in size) suspended in the water. In this process, a chemical called a ...
