A combined solar photocatalytic-biological field system for the mineralization of an industrial pollutant at pilot scale

Phenol removal and biofilm response in coupling of visible-light-driven photocatalysis and biodegradation: Effect of hydrothermal treatment temperature

“…Thus, photocatalysis can be effectively performed to degrade phenol but complete mineralization is difficult to achieve (Li et al, 2011). Although biodegradation could enhance mineralization of pollutants (Oller et al, 2007), DOC was not completely removed at the end of the experiment because some phenoltransformed intermediates were non-biodegradable (Sivalingam et al, 2004).…”

Coupling solar photo-Fenton and biotreatment at industrial scale: Main results of a demonstration plant

“…As previously demonstrated [23,24], wastewater can be biodegraded some time after complete disappearance of MPG. Photo-Fenton treatment time was therefore set to 150 min.…”

“…The first set of experiments has been performed in clean seawater in order to determine unequivocally (the pharmaceutical effluent contains other organic compounds) if the focus contaminant (MPG) could be substantially degraded and mineralised. Previous studies have demonstrated that photoFenton treatment is suitable for treating MPG dissolved in model water [23] with high salinity (NaCl 35 g L −1 ) [24]. These experiments have also demonstrated that the biodegradability threshold was attained after a certain treatment time and that photo-Fenton was a more suitable treatment than TiO 2 .…”

Comparison of different treatment alternatives for removal of pesticide from water solution

“…9 Unfortunately, not all organic molecules are readily biodegradable, and these are referred to as biorecalcitrant. 10,11 On the other hand, chemical treatment processes have also been employed to mineralize many organic chemicals, but the costs associated with these processes have limited their use. To overcome the economic problems, two alternatives were proposed.…”
