As an oxidizer, ozone introduces oxygen molecules into the water. This causes oxidization, pulling electrons from the contaminants and consuming them. Unlike chlorine, ozone is not a sanitizer. However, it is a very strong oxidizer, which can make it as effective as chlorine.
The problem with depending only on ozone to keep a pool clean is that it disappears extremely quickly. For that reason, it may not reach the far corners of a large pool or clean really dirty water. It is recommended that ozone be used in conjunction with a sanitizer, like chlorine.
Ozone is introduced into pools and spas using an ozonator. UV ozonators use ultraviolet light to make ozone, while CD ozonators use corona discharge similar to the electricity in a thunderstorm to create ozone. A tube transports the ozone from the generator to a pipe, mixing the ozone with the pool water. Because ozone can help reduce a pools dependence on chlorine, it can make the water more comfortable for swimmers.
