To date, one of the components of the global problem of water pollution has been the uncontrolled discharge of wastewater from industrial enterprises that use in their work technological solutions of heavy metals, including galvanic. Among the main components of wastewater generated in galvanic industrial enterprises, about 70% is zinc and its compounds, and the most toxic of the heavy metals contained in process solutions are Cr VI compounds. In view of this, it is important to improve the ferritization treatment of wastewater from zinc and chromium ions. A laboratory installation for the ferritization process with electromagnetic pulse activation (EMI) has been developed. This method of activation provides not only a reduction in energy costs, but also the appropriate degree of extraction of heavy metal ions, which allows you to get an aqueous solution that can be used in a circulating water supply system, and sludge disposed of as additives for alkaline cements. The influence of the strength of the electromagnetic field on the degree of extraction of zinc and chromium ions from wastewater by ferritization has been studied. It is determined that the best degree of purification from heavy metal ions is achieved at an electromagnetic field of 0.14T.
