Intensified elimination of iron and other thindispersed compounds from groundwater in situ by magnetic activation

ntensifying elimination of iron and other thindispersed compounds from groundwater in situ. The experiments were performed in aquifers of Quaternary intertill and alluvial deposits. Oxidation of bivalent iron ions by atmospheric oxygen and sedimentation of trivalent iron in an aquifer are more efficient when water is conducted through a magnetic water conditioner operating on a principle of a permanent magnet. Groundwater abstraction after aeration and magnetic treatment extends intensive oxidation of iron compounds: their low concentrations last twice or thrice as long as without magnetic water conditioning. Magnetic treatment of water by aeration stabilizes dissolved oxygen in groundwater or the oxygen adsorbed on the rock surface. Magnetic treatment during water aeration and abstraction is an effective method of drinking water quality improvement. This method may considerably reduce the costs of iron elimination in situ.
Keywords: water quality improvement, magnetic conditioning, iron elimination, aeration, oxidation
