The paper presents the results of the investigation on the efficiency of the potassium ferrate application in water conditioning processes: oxidation of pollutants of different composition by ferrate compounds; clarification of model solutions by coagulation; reduction of corrosive aggressiveness of aqueous solutions. The optimal conditions for the water clarification process using potassium ferrate were: reagent dose 1 mg∙dm^-3, pH close to neutral, and temperature 20°C. The oxidation rate of organic substances by the potassium ferrate solutions was 50% when applied in concentrations of 15-20 mg∙dm^-3. The studies on the possible application of the reagent as a steel corrosion inhibitor in neutral aqueous media were conducted. The degree of corrosion protection reached 60%, which indicated the prospect of using iron (VI) compounds as inhibitory additives.
