The invention relates to methods for water purification by a crystallization method and can be used in everyday life, food industry and medicine. The technical result of the claimed invention provides the development of such method for water purification by freezing, which ensures longer retention of biologically active properties of melt water. The method for water purification comprises filling a capacity with water for purification, cooling and its further freezing in said capacity until forming liquid concentrate of organic and inorganic admixtures, discharging said liquid concentrate, melting ice at a positive temperature to its unfreezing with subsequent discharging of purified melt water. Cooling, crystallization and melting of ice by heating are performed outside the working capacity by means of cooling and heating elements contacting with thermally conductive walls thereof. Ice melting under positive temperature and discharge of melt water are provided simultaneously, while melt water is discharged continuously or periodically into a thermostatically controlled storage capacity for its subsequent storage at a positive temperature, close to the temperature of ice melting. |
