METHOD OF DEIRONING OF UNDERWATER Russian patent published in 2004 - IPC

FIELD: purification of underwater for household application. SUBSTANCE: the invention presents a method of deironing of underwater. It is pertinent to purification of the water for economic - potable application from iron without usage of special sewage treatment plants. The method may be used for deironing of underwater and for the purpose it provides for injection in the underwater stratum of water enriched with oxygen-rich air. The injected water should contain a dissolved oxygen level of no less than 10 mg / l. At that they measure amount of air fed in the mixing with water, consumption of which makes no less than 50 % of the water consumption. That should ensure the effectiveness factor Fe= Wo / Wi > 5, where Wo - volume of pumped out water, Wi - volume of injection water. The method ensures increase of efficiency of process of the intrastratal purification\deironing of the underwater. EFFECT: the invention allows to increase efficiency of the intrastratal purification\deironing of the underwater. 1 ex
