Purpose: to determine the optimal parameters of a vacuum-ejection oxidizer for iron and manganese removal from groundwater.

Materials and methods. The nonchemical vacuum-ejection oxidizer for groundwater from the Trans-Volga zone of the Volgograd region, characterized by high iron (Fe) content reaching 30 mg/l or more, and manganese (Mn) content of 3 mg/l or more is studied. Theoretical studies of the vacuum-ejection oxidizer were conducted according to the Rechtshafner plan for a four-factor experiment. The adequacy of the obtained mathematical models was verified using the Fisher criterion.

Results. As a result of the research, a vacuum-ejection oxidizer design with optimal parameters for specific initial data taken from practical experiments was created.

Conclusions. The optimal parameters of the vacuum-ejection oxidizer, which improve the efficiency of groundwater iron and manganese removal, were determined by the regression analysis used in this mathematical experiment. These studies were conducted by selecting the ratio of the Venturi nozzle and vacuum chamber areas – factor х₁ = 1 : 6; the ratio of water and air flow rates – factor х₂ = 1 : 5; the number of mixing chamber stages – factor х₃ = 6; the ratio of the Fe²⁺ : Mn²⁺ concentration – factor х₄ = 10 : 1, which made it possible to obtain the value of the primary criterion YMn²⁺ = 0.80 mg/l with fixed values of the additional criteria (YFₑ²⁺ = 7.0 mg/l, YCO₂ = 30 mg/l and YpH = 8.50).
