“…As a result, the amount of catalytic iron that would be required to produce the same treatment results, and the volume of sludge consequently generated, could be strongly reduced; as well as some additional organic compounds (carboxylates) that are very difficult to treat by AOPs may otherwise be effectively treated by this methodology (Hermosilla et al 2009a;Hermosilla et al 2009b). Consequently, the photo-Fenton alternative has generally been shown to be more efficient in the degradation of effluent components than its dark version (Karimi et al 2010), and improves both the total quantity and the rate of TOC abatement in comparison to the UV/H 2 O 2 system (Catalkaya and Kargi 2007;Hermosilla et al 2009b;Hermosilla et al 2012).…”

“…Tambosi et al 2006). In fact, faster TOC removal rates have been shown at pH=2.8 (Hermosilla et al 2009a;Pérez et al 2002b). Besides, either a strong acidic media (pH=1.5), or under neutral-basic conditions (pH=8), slowed down the process mainly because of the instability that hydrogen peroxide and iron species showed in the solution .…”

“…Young or middle-aged leachate (less than 10 years old), are acidogenic type, they have a high organic load of low molecular weight and biodegradability (Biological Oxygen Demand -BOD 5 /COD) between 0.6 and 1 [10]. While old leachate (over 10 years old) is methanogenic type, have a high concentration of organic matter where the refractory type is predominantly and therefore are not biodegradable with an index BOD 5 /COD <0.3 because this inhibits biomass action [3], [11], [12].…”

“…(1)), This reactions depends on the pH [14]. So that in the absence of any other oxidizable substance, the net reaction of H 2 O 2 , gives as result the formation of H 2 O and O 2 catalyzed by iron [10]. Marí a Santin-Gusman, Javier Moreno-André s, Mónica Cisneros-Abad, and Silvio Aguilar-Ramí rez application of system for the treatment of landfill leachate, which have reported promising results reaching removals between 60%-75% COD [10], [12], [15]- [18].…”
