DEVICE FOR DEIRONING OF GROUND WATERS Russian patent published in 2013 - IPC C02F1/46 C02F1/64 

FIELD: chemistry.

SUBSTANCE: device of water deironing includes not less than two vessels, which represent vertically placed cases of cylindrical shape from dielectric, on internal surface of which placed are inert anodes 7 in form of spiral, and in the middle iron cathodes 8 in form of round rods; electrified dampers 9, connected with supply tube of pump 3, are fastened to inputs into cases, air-valves 10, connected with ventilating tubes 11, are located in upper parts of cases, on outputs of cases placed are tubes for discharge of clean water 12 with electrified dampers 13 and discharge of washing water 14 with electrified dampers 15. Sensor of water discharge 16 and sensor of iron content in water 17 are placed on tube of clean water discharge. Tube of washing water is connected to tangential input of hydrocyclone 18, whose upper output is connected with tube of washing water dumping 19 inti sewage, and lower output is directed into reservoir for iron hydroxide utilisation 21. Control unit 5 is connected by means of conductors with source of constant current 4, all electrified dampers, sensor of water consumption and sensor of iron content in water.

EFFECT: increase of deironing process reliability, guaranteed quality if purified.
