Abstract
Abstract The disclosed method and apparatus simultaneously purifies air and water contained in an indoor institution such as an indoor swimming pool facility. Air from the interior of the institution is first treated in a cyclone to remove dust, bacteria and odors, then mixed with ozone generated from a separate air source to form an air-ozone mixture which is distributed in the form of fine bubbles in an air/water contact sterilizing chamber. Water from the pool of water in the indoor institution is filtered and transferred to the sterilizing chamber. In the sterilizing chamber, contact of the filtered water and air-ozone mixture acts to simultaneously purify both. The purified air is returned to the indoor institution after moisture removal, ozone elimination and temperature adjustment. Similarly, the purified water is returned to the pool of water after ozone elimination, temperature adjustment and chlorination.
