METHOD OF PURIFYING WATER FROM RADON AND RADON SUBSTITUTE DECOMPOSITION PRODUCTS, DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC C02F1/58 C02F1/28 G21F9/12 G21F9/14 B01D24/46 

FIELD: chemistry.

SUBSTANCE: method for purifying water from radon and radon decay substitute products involves filtering the purifying water through sorbing material and backwashing the sorbing material. Filter 3 with sorbing material is protected by a screen. The backwashing is carried out with water heated to a temperature of from 50 to 85°C, which is then collected in a collecting container 9 and maintained until the radon decay and radon substitute products. A device for purifying water from radon and radon decay products includes a filter 3 with sorbing material, a line for supplying purified water 1, a line for the removal of purified water 5, a backwash filter system, a source of hot water 8 with a temperature of 50 to 85°C, a storage tank 9 for rinsing water for the time of radon decay and radon decay substitute products, a screen.

EFFECT: invention makes it possible to increase the radiation safety of water purification from radon and radon decay substitute products, and to increase the life of the sorbent material and to effectively perform water purification and safe maintenance.
