Evaluation of the Activation Procedure on Oxone Efficiency for Synthetic Olive Mill Wastewater Treatment

Abstract: Wastewater from the olive oil industry is an environmental problem which is growing in the Mediterranean region. Presence of phenolic compounds and high organic matter load are characteristics of this effluent that make it difficult to treat. In this study, the applicability of sulfate radical based advanced oxidation processes (SRbAOPs), using peroxymonosulfate (PMS) as oxidant, was evaluated in the treatment of synthetic olive mill wastewater (OMW). Different procedures for PMS activation were studied such a… Show more

“…The negative effect of an excess of PMS is not always detected and depends on a number of factors such as pH, target pollutants nature, temperature, etc. Hence, some works [19,20] have reported the existence of an optimum PMS concentration in effluents from the olive oil manufacturing process (synthetic or real). The PMS/Fe(II)/Fe(III) system is assumed to behave analogously to Fenton´s chemistry [15], i.e., through generation of highly reactive radicals:…”

“…The main reactive species involved is hydroxyl radicals (•OH), but other species can also present important roles depending on the characteristics of molecules and may vary according to the specific process. Fenton (Fe/H 2 O 2 ); photo-Fenton (Fe/H 2 O 2 /light); ozonation (O 3 ); persulfate (S 2 O 8 2− ); catalytic oxidation; photocatalysis (catalyst/light); and their multiple combinations and other alternatives compose the AOPs groups and have been extensively applied for the successful elimination of pollutants [7,[9][10][11][12]. Different technologies in the AOPs group may possess more adequate features depending on the desired task.…”
