The Journal of the Swimming Pool and Spa Industry 39 Field Evaluation of a Bi-Polar Oxygen Sanitation System and a Mineral Purification System

body and sun tan oils, skin cells, hair, and detergents from creams, lotions and shampoos all of which create a chlorine demand. Rain water and wind also contribute organic matter into recreational waters in the forms of algae, dirt, leaves and various particulate matter along with air pollution. All of these materials add to the chlorine demand, and reduce chlorine’s effectiveness as a disinfectant. Chlorine also acts as a skin and eye irritant (Clark and Berman, 1983). Recent research indicates that chlorinated or-ganics can cause cancer in humans, as well as other health and reproductive problems. Chlorination of water containing organic contaminants results in the formation of chlorinated organics. With the increased knowledge of the toxic poten-tial of chemicals in water, a large number of physical and chemical methods are being investigated in an attempt to purify recreational waters. Of particular interest and importance is the use of hydroxyl radicals and ions as superior oxidizers when compared to chlorine compounds. As described by David Woodbridge, Ph.D. in his paper entitled Hydroxyl Radicals and Ions as Swim-ming Pool Water Purifiers, the production of hydroxyl occurs by many different reactions. The asymmetrical distribution of the hydrogen and oxygen atoms in the water molecule appears to provide a structure where numerous types of energy exchange can remove one of the hydrogen atoms and leave the hydroxyl entity. Occurrence of the hydroxyl group will depend upon the building of the proton (hydrogen atom) to the diatomic species OH+, OH0, OH – (Woodbridge, 1994). Studies of new methodologies for treating waste water have shown that the hydroxyl radical is one of the most powerful oxidizing agents that can exist in water.
