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.

Both chambers will be able to sequentially form carbonated water when both carbon dioxide and water is contained in one of the chambers.

Abstract: This is a device for injecting air into a water supply under pressure in a closed system. One embodiment consists of two sliding pistons inside a closed housing. The two pistons are connected to each other by a connecting rod. They are positioned so that they slide alternately toward one end of said housing and then toward the other end. They are propelled first in one direction and then the other by water entering under pressure alternately through two openings, one on each side of the driving piston and exiting alternately through two other openings on opposite sides of said driving piston. These valves are opened and closed alternately in pairs by a means driven by the movement of said pistons. The second piston, driven by the first, draws air into said housing as it moves in one direction and then forces it into the water as it moves in the other direction.

Abstract: This is a device for injecting air into a water supply under pressure in a closed system. It consists of two sliding pistons inside a closed housing. The two pistons are connected to each other by a connecting rod. They are positioned so that they slide alternately toward one end of the housing and then toward the other end. They are propelled in one direction by water pressure entering the housing through an opening from an outside source. They are propelled in the opposite direction by a coil spring. This device can employ any one of several different means to increase and decrease the water pressure on one piston thereby alternately causing the coil spring to be compressed and then allowed to expand. This causes the second piston to draw air into the housing through a check valve when the coil spring is being depressed and then allows the air to pass through a check into the path of the flowing water when the coil spring is expanding.

The cooling tower may include a turbine driven fan which utilizes as a motive fluid water for cooling and washing the coils of scale.
