“…The Fenton process is one of the most cost-effective AOP [9][10][11][12][13]. It was discovered more than one hundred years ago by Henry J. Fenton, who reported that H 2 O 2 could be activated by iron salts to oxidize tartaric acid [14].…”

Esta es la versión de autor del artículo publicado en: This is an author produced version of a paper published in: AbstractThis study presents a critical review on the application of magnetite-based catalysts to industrial wastewater decontamination by heterogeneous Fenton oxidation. The use of magnetic materials in this field started only around 2008 and continues growing increasingly year by year. The potential of these materials derives from their higher ability for degradation of recalcitrant pollutants compared to the conventional iron-supported catalysts due to the presence of both Fe(II) and Fe(III) species. In addition, their magnetic properties allow their easy, fast and inexpensive separation from the reaction medium. The magnetic materials applied up to now can be classified in three general groups: magnetic natural minerals, in-situ-produced magnetic materials and ferromagnetic nanoparticles. A survey of the catalysts investigated so far is presented paying attention to their nature and competitive features in terms of activity and durability.2

“…Ozone can oxidize other compounds in two different ways: directly reacting with dissolved substances; or indirectly, by hydroxyl radicals that are produced in its decomposition process (Esplugas et al 2002). Due to the short half-life of ozone, continuous ozonation is required to keep the reaction going on.…”

“…An UV process is based on supplying energy to chemical compounds as radiation, which is absorbed by reactant molecules that are promoted to excited states and may further promote new reactions along treatment (Esplugas et al 2002;Legrini et al 1993). In general, UV alone is not considered as an effective treatment when applied standalone in comparison to other AOPs (e.g.…”

“…In particular, it has been demonstrated that radiation with a wavelength lower than 400 nm is able to photolize H 2 O 2 molecules (Esplugas et al 2002;Legrini et al 1993). As a result, the addition of H 2 O 2 to an UV treating system has been reported to significantly improve both color and TOC removals in comparison to a standalone UV treatment; even when low H 2 O 2 concentrations were supplied (Catalkaya and Kargi 2007).…”

Paper industry is adopting zero liquid effluent technologies to reduce fresh water use and meet environmental regulations, which implies water circuits closure and the progressive accumulation of pollutants that must be removed before water re-use and final wastewater discharge. The traditional water treatment technologies that are used in paper mills (such as dissolve air flotation or biological treatment) are not able to remove recalcitrant contaminants. Therefore, advanced water treatment technologies, such as advanced oxidation processes (AOPs), are being included in industrial wastewater treatment chains aiming to either improve water biodegradability or its final quality. A deep review of the current state of the art regarding the use of AOPs for the treatment of the organic load of effluents from the paper industry is herein addressed considering mature and emerging treatments for a sustainable water use in this sector. Wastewater composition, which is highly dependent of the raw materials being used in the mills, the selected AOP itself, and its combination with other technologies, will determine the viability of the treatment. In general, all AOPs have been reported to achieve good organics removal efficiencies (COD removal >40%; and about an extra 20% if AOPs are combined with biological stages). Particularly, ozonation has been the most extensively reported and successfully implemented AOP at an industrial scale for effluent treatment or reuse within pulp and paper mills; although Fenton processes (photo-Fenton particularly) have actually addressed better oxidative results (COD removal ≈65-75%) at lab scale, but still need further development at large scale.
