ABSTRACT:
An apparatus for purifying water, such as for desalinization, includes a source of a heated air stream, the heated air stream having a temperature above an ambient temperature. A diffusion tower having high surface area material therein receives a water stream including at least one impurity and creates at least one region having thin films of water therein from the water stream. The heated air stream is directed over the thin films of water to create a humidified air stream that is at least substantially saturated. At least one direct contact condenser is in fluid communication with the humidified air stream for condensing the humidified air stream, thus producing purified water. A power plant can include the apparatus for purifying water, where energy to heat the air stream is provided by low pressure condensing steam.
