The electrochemical degradation of 2.5 L of Ponceau SS diazo dye solution in acidic sulfate medium has been studied in a pre‐pilot flow plant with a boron‐doped diamond (BDD)/air‐diffusion or Pt/air‐diffusion cell connected to an annular photoreactor. The decolorization and mineralization was enhanced in the order: electrochemical oxidation with electrogenerated H 2 O 2
