FIELD: chemistry.
SUBSTANCE: method of purifying drinking water from strontium is carried out by ion exchange. A filter is used with a charge consisting of a monodisperse strongly acidic cation in Na- or H-form with a granule size of 0.6-0.7 mm. The process is carried out in a filter with a clamped loading layer with a ratio of diameter and load height of not more than 0.8. The filter equipped with drain slotted caps in a sheath of a metal mesh with a mesh size of 0.28-0.50 mm.
EFFECT: increasing the selectivity of the extraction of strontium, stabilizing the flow of treated water, increasing the depth of purification from hardness salts and salts of strontium, increasing the length of the filter cycle.
