METHOD FOR PURIFICATION OF WATER FROM RADON AND RADON DAUGHTER PRODUCTS Russian patent published in 2021 - IPC C02F1/58 C02F1/28 G21F9/12 G21F9/14 B01D24/46 

FIELD: treatment of water.

SUBSTANCE: invention relates to treatment of water, namely to a method for purification of water from radon and radon daughter products. The method includes filtering the purified water through a sorbing material and washing the sorbing material with water heated to a temperature of no more than 90°C, collecting and sustaining the wash waters in a collection tank until the decay of radon and short-lived radon daughter products. After sustaining in the collection tank, the wash waters are therein purified from long-lived radon decay products by filtering through an additional filter containing an inorganic sorbing material in form of hydrated zirconium or manganese oxides.

EFFECT: proposed method allows achieving deactivation of wash waters formed during purification of water from radon and radon daughter products.
