Studies of the purification of multicomponent galvanic effluents by the electrospark method using metal loadings (Fe, Al) and low-voltage (up to 1000 V) equipment have been carried out. It is shown that the degree of cleaning depends on the specific energy of processing, the height of metal loading of the reactor, and practically does not depend on the energy of the pulse and the speed of its input into the liquid being processed. The concentrations of heavy metals (Ni2+, Zn2+, Cr6+ + Cr3+, Cu2+, Fe (Σ)) in the treated water are significantly lower than their maximal permissible concentration values regulated by developed countries.
Keywords: multicomponent galvanic effluents, electrospark method, reactor with metal loading.
