Industrial effluents are often discharged in an uncontrolled manner, without adequate levels of treatment, and contain refractory and toxic compounds, and advanced oxidation processes are proving to be an attractive option. Such processes, in addition to their high efficiency and high degradation rate, have low cost and are adapted to environmental concerns, making their use viable. Among these processes, the Fenton process, which uses iron (II) as a catalyst and hydrogen peroxide as an oxidizing agent, has been highlighted, forming hydroxyl groups that are highly reactive to unwanted compounds in the medium. The Fenton process has been successful in the treatment of recalcitrant organic compounds. It has the disadvantage of producing a significant volume of sludge, which requires additional treatment and removal. The fluidized-bed Fenton method (FBF) employs carriers that reduce the sludge production.
