The method of natural water treatment from manganese compounds on synthesized from manganese ore sorbent-catalyst was proposed. Salt content of sodium chlorides on efficiency of sorbent-catalyst in static conditions was explored. Salt content and pH value solution influence on residual concentration of manganese compounds in treated water was determined. The equation which describes the influence of those factors was obtained. The water treatment with high salt content ought to carry out with high pH value available to potable water.

Key words: sorbent-catalyst, salt content, sodium chloride, pH value, ionic strength, oxygen.
