METHOD OF PURIFYING WATER FROM SILICATES Russian patent published in 2014 - IPC C02F1/60 C02F1/28 B01J20/08 B01J20/34 C01B33/26 C02F103/02 

FIELD: chemistry.

SUBSTANCE: in order to realise method waters to be purified are filtered through layer of activated aluminium oxide, preliminarily modified by 0.5% sodium aluminate solution. Regeneration of spent activated sodium aluminate solution is realised by 0.1-0.5% sodium aluminate solution.

EFFECT: increased sorption capacity of charge by absorbed silicon, increased duration of filter-cycle between charge regenerations and creation of wasteless technology of water desilicinisation with re-application of spent regeneration solution.
