The paper presents the results of laboratory and bench experiments to determine the rational modes of galvanochemical cleaning of chromiumcontaining waste water from JSC "Russian Chrome 1915". Recommendations are given on the modernization of the existing purification system of the enterprise on the basis of the developed technological scheme, which can be realized through the creation of two autonomous units: neutralization and separation. The developed technology foundations can be the basis of a new approach in dealing with a wide range of chromium-containing wastewater treatment problems.
