WATER TREATMENT METHOD AND PLANT Russian patent published in 2009 - IPC C02F9/06 C02F1/22 C02F1/46 

FIELD: chemistry, water purification.

SUBSTANCE: invention refers to water treatment and can be used for tap water purification and activation in food industry, medicine, for sea water conversion, etc. Water treatment method is implemented in closed operating capacity and includes heat rejection enabling water local bulk crystallisation by ice crystals silvering in amount 50÷70 % of initial water weight surrounding heat exchanger, contaminated water drain through the port in capacity bottom and through the channel 0.5÷2 cm above capacity bottom, and removal of frost accumulation. Level of operating capacity filling with initial water is determined by height of channel port draining surplus initial water resulted from operating capacity filling and during initial water crystallisation due to its volume increase to additional capacity. Frost accumulation is removed by heating the ten shaped by multistage coil pipe and mounted in working capacity to surround heat exchanger directly in ice zone. During removal of frost accumulation, melt water is exposed to electrochemical activation carried out in special electrochemical activation tank separated with diaphragm to anode and cathode chambers. Herewith cathode chamber is pipeline connected to working capacity.

EFFECT: water purification from dissolved cancerogens, mutagens and gases, heavy hydrogen isotope, deuterium and tritium.
