The article presents the research results for a water treatment technology that removes chemical impurities with a ferrite reagent. The process scheme is a hydrocyclone filter for preliminary water purification from large suspensions, a vertical settler, a chamber for mixing the components of the reagent and a centrifuge for sludge dewatering, which can be used as a magnet. In the course of the experiments, the required cooling time intervals were established and the absorption effect of the ferrite reagent with respect to chemical impurities was determined. The settling was carried out at various intervals for 0.3, 1, 2 and 4 hours. It was found that the maximum permissible concentration of impurities in the test water was achieved within 2 hours of settling at a dose of 50 ml.
