METHOD OF PURIFICATION OF UNDERGROUND WATER FROM IRON Russian patent published in 2012 - IPC C02F1/64 C02F9/02 

FIELD: chemistry.

SUBSTANCE: water from underwater springs is supplied by submerged pump 1 through magnetic field concentrator 23 to racks of ejector nozzles 3, where it is twisted with floating porous filling 6 in narrowing clearance 8. Water is dispersed and saturated with air oxygen. In collection tank 2 saturated hydrogen sulfide and carbon dioxide are removed. Liquid medium is clarified during flowing through a set of coaxial cylindrical partitions 15. Clarified liquid medium is supplied to input of generator 5 from vortex chamber 11. In volume of clearance 16 of generator 5 iron hydroxide is formed. Sorption of concentrate is performed, after which it is returned to input of magnetic field concentrator 23. Filtration of main part of water flow is performed on porous partitions 17 of generator 5. Filtrate is supplied to filter 26. Water is supplied to clean water reservoir 48, where from it is supplied to consumer or to regeneration of filter 26.

EFFECT: invention makes it possible to reduce energy consumption and increase efficiency of purification of underground water from iron.
