This work was focused on the diaphragm discharge generated by DC non-pulsed high voltage in water solutions containing organic dye Direct Red 79 and selected electrolytes. The dye decomposition as a function of discharge conditions (discharge polarity, input power, etc.) and an influence of solution properties on the dye removal was investigated. The dye degradation went much faster in the negative discharge, dye concentration dropped to approximately 20 % after the first 10 minutes of the discharge treatment. The increasing input power enhanced the dye removal almost linearly. The strong influence of electrolysis on the dye decomposition was confirmed, as well as the added electrolyte kind and its concentration. Optimal solution conductivity should be adjusted for the most efficient process operation.
