Hybrid systems with oxidative system integration have the
potential in reducing toxicity and enhancing biodegradability of
wastewater within a shorter reaction time . Amongst
advanced oxidation processes, Fenton is a well-proven oxidative
system that oxidizes recalcitrant organic contaminants in effluents
by utilizing strong hydroxyl radical generated in-situ through the
reaction of iron with hydrogen peroxide. However, by using Fenton
oxidation as a stand-alone approach is generally not lucrative due
to the accompanying high reagent consumption . Accordingly,
combined Fenton–SBR has been an effective and economical
method for recalcitrant wastewaters treatment
