New sorbent-catalyst using in water treatment technology from manganese compounds allows get qualitative water that satisfies present quality requirements. Salt content of doubly charged ions such as calcium, magnesium and sulphates on sorbent-catalyst efficiency in article was explored. It was established that singly ions of sodium chlorides and doubly charged hardness ions influence on residual concentration of manganese compounds in liquid phase. It was found that influence of doubly charged ions on water purification form manganese compounds with sorbent-catalyst using was substantial. Calcium and potassium carbonates leaching from sorbent-catalyst was confirmed. The solution pH value increased to optimal for manganese compounds removal range within sorbent-catalyst contact time. Experimental data with fitted coefficients were described by proposed theoretical model. The theoretical model makes it possible to calculate pH value, solution air oxygen saturation and salt content influence on water treatment from manganese compounds with sorbent-catalyst using.Downloads
