METHOD OF PURIFYING UNDERGROUND WATERS FROM BORON IONS AND DEVICE FOR ITS REALISATION Russian patent published in 2014 - IPC C02F1/46 

FIELD: chemistry.

SUBSTANCE: method lies in directed laminar movement of purified water, realised under action of constant electric field with potential gradient in the range from 2 to 5 V/cm through reservoir, located at angle from 30° to 45° upward and having pentagonal cross section with inert electrodes located in parallel way. In upper part of reservoir water movement is separated into two flows, first of which, containing water, purified from boron ions, is directed by horizontally placed pipe to consumer, and second one, containing number of boron ions increased in the process of purification, is directed by inclined downward at angle from 15° to 30° pipe of smaller diameter into outlet. Ratio of areas of cross section of horizontally located pipe and pipe of smaller diameter constitutes from 1:10 to 1:3.

EFFECT: increased process reliability, guaranteed quality of water purification from boron ions, provision of flexible automatic control, compactness of equipment.
