The study was focused on the electroplating waste after electro-spark treatment using granular metal-deposited and low-voltage (up to 1000 V) discharge pulse sources. Research methods - physical experiment, analysis and generalization of information. The search for efficient regimes for the flow-through cleaning of electroplating waste was done using the laboratory equipment by means of the electrospark dispersion method with the use of granular metal loading in the flow regime, with a change in the specific processing energy; pulse processing parameters provided that the energy of a single discharge pulse is fixed; discharge pulse repetition frequency with fixation of the volumetric flow velocity of the liquid; flow pattern; the number of pulses per unit volume of fluid at a fixed total processing energy. Analysis of all regimes has shown that the main factor that influences the peeling of galvanic isolation is the specific processing energy, which for moderate pollutant concentrations can be less than 65 kJ/dm (18 kWh/m), and the flow pattern of the liquid flow. Other values that are varied in operation are either a tool for scaling the cleaning processes, or the means of regulating the operating modes of electrical equipment.
