ASSESSMENT OF DEOXYGENATION EFFICIENCY FOR WATER OF VARIOUS MINERALIZATION

The study of the influence of iron -containing redoxites on the efficiency of water deoxidation was carried out and described. During this study, the dependence of the efficiency of water deoxygenation on the filtration speed (from 1.50 to 7.50 m/h) was also determined. The residual content of oxygen and the content of dissolved iron in water were determined. As a result, it was shown that an increase in the filtration rate within the specified limits has a rather strong effect on the residual oxygen concentration, namely its increase from 0.30 mg/dm(3) to 1.51 mg/dm(3). The residual oxygen content also depends on the reaction of the medium, since an increase in the residual oxygen concentration was noted when the pH of the medium increased from 7.770 to 9.75, but the residual iron content was little dependent on these factors (in all cases it did not exceed 0.25 mg/dm(3)). When using columns with KU -2-8 cationite in the Na* form in the scheme of the redox system, almost complete removal of iron ions from water and sodium cation softening of tap water was noted.
