Ozone is the only powerful oxidizing agent for swimming pools. The natural and biodegradable ozone completely reduces the consumption of chlorine. Treatment of pool water with available chemicals such as chlorine is highly hazardous to health. Ozone has to be replaced in the place of chlorine and other chemical disinfectants. Ozone provides a clean, odorless and healthier pool which does not cause red eye or skin irritation. Improvement in quality of pool water is attained by elimination of chemical content. Swimming pool water pollution is mainly caused by swimmers. The pollutants can be divided into three groups Microorganisms, organics and solid particles.
