摘要：In the Tyumen region, groundwater is widely used for household and drinking water supply, the chemical composition of which is influenced by the increased marshland and peat resistance of soils and, in some cases, the presence of oil and gas-bearing horizons. Underground water typically has a high content of dissolved organic impurities (permanganate oxidability 11.7 - 23.0 mg/dm3), elevated concentrations of free carbon dioxide (20.0 200.0 mg/dm3), hydrogen sulfide (0.20 - 1.95 mg/dm3) and methane (5.3 - 60.0 mg/dm3), dissolved forms of iron (1.14 - 14.00 mg/dm3), manganese (0.02 - 3.80 mg/dm3).

Underground water typically has a high content of dissolved organic impurities (permanganate oxidability 11.7 - 23.0 mg/dm3), elevated concentrations of free carbon dioxide (20.0 200.0 mg/dm3), hydrogen sulfide (0.20 - 1.95 mg/dm3) and methane (5.3 - 60.0 mg/dm3), dissolved forms of iron (1.14 - 14.00 mg/dm3), manganese (0.02 - 3.80 mg/dm3). Analysis of iron removal plants operation was performed. Analysis of the region's iron removal plants showed that the process of iron removal of water depends on the degree of saturation of water with air oxygen with parallel removal of dissolved gases. Pre-degassing of water with high efficiency degassers is a necessary link of the process chain even when reagent purification techniques are used. Analysis and systematization of existing degassers to remove dissolved carbon dioxide have shown that despite the high-efficiency of some degasser models, they are complex in design and require considerable capital construction and operation costs. There is a need to develop a design not complicated in design, having high degassing efficiency at low economic costs.
