METHOD OF THE WATER PURIFICATION Russian patent published in 2007 - IPC C02F1/22 C02F103/04 

FIELD: chemical industry; food industry; pharmaceutical industry; power industry; and other industries; methods of water purification.

SUBSTANCE: the invention is pertaining to the methods of the water purification by its congealing and straight thawing and may be applied in the chemical industry, food industry, pharmaceutical industry, power industry and other industries. The method of the water purification includes its complete congealing, the subsequent straight thawing and sedimentation. Repeat these methods in 2-3 hours after removal of the sediment, gases and the volatile substances from the thaw water. Removal of the volatile substances and gasses is conducted by the thaw water vacuumization at the residual pressure of (0.1-0.6)·10⁵ Pa. The method ensures improvement of the water quality, production of the purified water with the lowered content of calcium salts. Removal of the volatile soluble substances from the water decreases the time of the water transition from one aggregation state into another.

EFFECT: the invention ensures the improved water quality, production of the purified water with the lowered content of calcium salts, the decreases time of the water transition from one aggregation state into another.
