ozonation
n.— «“Ozonation,” as it’s called, is far from experimental, and many other cities—including Tampa, Orlando, New York and Los Angeles—use it already. Ozone like that found in the atmosphere is added to the water. Then the water and ozone are zapped with an electric charge, which destroys disease-causing microbes and eliminates particles that cause bad taste and odor.» —“Improving West Palm’s water could cost $34 million” by Thomas Collins in West Palm Beach Palm Beach Post (Florida) June 2, 2006.
