DEVICE FOR WATER SOFTENING Russian patent published in 2008 - IPC C02F5/02 C02F1/02 

FIELD: technological processes, water treatment.

SUBSTANCE: invention is related to the field of water treatment, in particular, to water softening by deposition of hardness salts with the help of seeding material. Device contains vertical reservoir with conical bottom and nozzles of water inlet and outlet, contact mass, for instance, sand, recirculator in the form of two coaxially installed vertically one inside another tubes, steam nozzle installed in the bottom part of internal tube coaxially to it, nozzle of carbonic gas and non-condensed steam exhaust, turbulence promoter installed in the top part of recirculator under the cover of external tube coaxially to it, which represents frame, on which screw is fixed, being installed in internal tube, and plates installed in tube space. Screw and plates are made of aluminium or iron. Positive potential is sent to turbulence promoter relative to reservoir and recirculator. Device makes it possible to increase efficiency of water treatment process from hardness salts.

EFFECT: increase of efficiency of water treatment process from hardness salts.
