Abstract: FIELD: electroplating. 
     SUBSTANCE: invention relates to the field of electroplating. The method includes placing in the technological sequence of process baths and washing baths for preliminary, main and post-processing operations, the effluents of which are fed to the treatment plant, and the washing operations are carried out by submersible and jet methods, and water is supplied to the immersion washing baths through electromagnetic valves controlled by a relay time, taking into account the required technological exchange rate in them or the value of the washing criterion for a specific operation, while the washing of the parts in each operation is sequentially carried out in one jet-dynamic washing bath and in the immersion washing bath, the drainage of water from which is carried out into its overflow pocket, or connected through a mechanical cleaning filter with an intermediate tank equipped with an overflow pipe, a drain valve and a pump, the outlet of which through a control valve and a mechanical cleaning filter is connected to a manifold for jet washing installed in the jet- dynamic flushing, equipped with a branch pipe for draining water contaminated with the main component to be washed through a ball valve, or equipped with an overflow pipe and a drain valve, the outlet of which is connected to the inlet of the pump, the outlet of which, through a control valve and a mechanical filter, is connected to a manifold for jet flushing, installed in a jet-dynamic flushing bath, equipped with an overflow pipe and a branch pipe for draining water contaminated with the main component to be washed through a mechanical filter and a ball valve, in this case, the outlets of the ball valve of the jet-dynamic washing bath, depending on the type of the process bath and the processing stage, are connected, respectively, to an intermediate tank installed next to the process bath, and through an intermediate container installed next to the jet-dynamic washing bath, equipped with an overflow pipe and a drain valve, with pump inlet, the outlet of which, through a control valve and a mechanical cleaning filter, is connected to a manifold for jet flushing, installed in the process bath of the corresponding operation, the overflow pocket of which is equipped with a drain pipe connected to an intermediate tank equipped with an overflow pipe and through a drain valve connected to the pump, the outlet of which through the filtering unit and the control valve is connected to the process bath, or to the inlet of the pump, the outlet of which through the control valve and the mechanical cleaning filter is connected to the manifold for jet flushing, installed in the process bath of the corresponding operation, the overflow pocket of which is equipped with an overflow pipe and a drain pipe connected through the drain valve to the pump, the outlet of which through the filtering unit and/or the control valve is connected to the process bath, with an intermediate tank equipped with an overflow pipe and a drain valve connected to a pump, the outlet of which is connected through a control valve to the process bath and to an intermediate tank equipped with an overflow pipe, and through drain valve with pump, the outlet of which through a control valve is connected to the jet flushing manifold installed in the overflow pocket of the process degreasing bath, or to the pump inlet, the output of which is connected to the inlet of a three-way ball valve, one of the outputs of which is connected to the jet flushing manifold installed in the overflow pocket of the process degreasing bath , and the second through a mechanical cleaning filter - with a jet washing manifold installed in the overflow pocket of the process bath. 
     EFFECT: invention is aimed at reducing the consumption of clean water and wastewater entering the treatment plant, the time for washing parts, increasing the efficiency of the latter and expanding their functional and technological capabilities and galvanic lines in general.
