METHOD OF THE WATER PURIFICATION Russian patent published in 2007 - IPC C02F1/22 C02F103/08 

FIELD: alimentary industry; pharmaceutical industry; chemical industry; power industry; other industries: methods of the water purification.

SUBSTANCE: the invention is pertaining to the methods of the water purification by freezing and thaw and may be used in alimentary, pharmaceutical, chemical, power and other industries. The method of the water purification includes the complete freezing of the water, the ice aging at the temperature below the temperature of the initial water freezing during the time interval of no less than 1 hour, the ice thawing at the temperature of 50-60 °С, settling of the thaw water from 24 to 48 hours with the following siphonage of up to 90 % of the gained water volume without stirring of the settling. It is preferable after the settling process to gate the water through the filtering partition with the pores size of not exceeding 10 microns. The invention allows to decrease the overall dimensions of the used equipment, to improve the quality and efficiency of the purification process, to produce the purified water with calcium salt content of less than 50 mg/l.

EFFECT: the invention ensures reduction of the overall dimensions of the used equipment, improvement of the quality and efficiency of the purification process, production of the purified water with calcium salt content of less than 50 mg/l.
