“…Electrical discharge can be generated directly in the treated liquid or in the gas intrusions in the liquid phase. Moreover, plasma can interact with the liquid indirectly when the discharge occurs in gaseous phase in the vicinity of the liquid surface and then active plasma species are further transferred via the surface to the bulk of the liquid [ 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ].…”
