Abstract: A water atomization system for cooling, aeration, and pollution control gas scrubbing, wherein a multiple blade fan is mounted in a tower cap, or positioned directly inside of a tank or tower. Water exiting nozzles impinges off the fan blades, thereby propelling and rotating the fan. The rotating fan atomizes the water into fine droplets, and forces air through the atomized water. For cooling and aeration applications, heat or dissolved gasses in the water are liberated and carried away by the flowing air. The system can also be used for pollution control, whereby instead of air traveling through the device, gasses of combustion flow through it. The water traps, absorbs, and chemically reacts with suspended particles in the flowing gasses.
