A method and apparatus are disclosed wherein air and water are simultaneously introduced under high pressure, concurrently upwardly, within a confined zone. Air is introduced from a point immediately below the water inlet point and travels upwardly at high velocity. Water is introduced thereabove in a manner to form extremely finely divided particles moving upwardly as a swirling mass. Because of the velocity of water and air introduction, the water droplets are driven with high impact against the upper surface of the confined zone and thereafter proceed downwardly. The impact of the water droplets against the upper surface causes them to be reshaped and broken apart, thereby providing still greater overall water-air exposure. By reason of the constant flow of high velocity air, the particles are maintained in suspension for a long period of time. Both air and water preferably are heated, especially in use under cold climatic conditions. As a result of the described mode of treatment, a high degree of water purification in various respects is accomplished. During the water and air intermingling, the water treating zone is vented for release of impurity-laden air. The particular apparatus disclosed is especially adapted for water storage, including automatic water shutoff and flow responsive to periodic water use, as may be especially desirable in home installations. |
