Development of a Simplified Technology for Removing Iron from Groundwater to Meet the Drinking Needs of an Agricultural Enterprise

The possibility of removing iron from underground water by aeration is being considered. To increase the efficiency of aeration of water and, accordingly, more complete removal of iron, water-drying units are used, which are used to cool recycled water in cooling towers. Depending on the presence of iron in the aqueous medium, the removal was carried out in 2 stages, the oxidation of Fe2+ ions to a trivalent insoluble state by aeration of air and the release of undissolved trivalent iron by precipitation from the composition of the treated water, respectively. The corrugation of the sprinkler tube ensures the flow of water through it in a thin layer. This, in turn, ensures more complete contact of water with air and, accordingly, increases the efficiency of iron removal. These tubes are light in weight and overall dimensions are convenient for installation and transportation. Accordingly, the overall dimensions and weight of the tubes are ideally suited for the process of aeration of a small amount of water in the field. As a result, the iron content in aerated water is 0.05 mg/l. This shows that the chemical composition of water in terms of iron content is 6 times lower than the normative indicators. For the existing economy, a simplified, budgetary scheme for de-ironing of borehole water has been developed.
