METHOD OF THE VACUUM DEAERATION OF THE TAP WATER Russian patent published in 2008 - IPC C02F1/20 F22D1/50 

FIELD: chemical industry; other industries; methods of purification of the tap water from the gases and chlorine.

SUBSTANCE: the invention is pertaining to the method of the tap water purification from the gases and chlorine. The method of the vacuum deaeration of the water consists in vacuumization of the space over level of the being deaerated water. The vacuumization process is alternating with the idle time, during which conduct changeover of the upper and the lower layers of the water at the expense of their convective flow. At that before the water running in the vessel it is heated up to the temperature of the deaerated water and the influx is executed onto the surface of the latter. At that the space over the level of the deaerated water is disinfected by the wet saturated steam. The convective flow is exercised at the expense of density gradients and the temperature of the water. The technical result of the invention is simplification of the equipment design, the improved quality of purification of the tap water, and also the decreased power input in the process of operation.

EFFECT: the invention ensures simplification of the equipment design, the improved quality of the tap water purification, the reduced power input in the process of the equipment operation.
