Enhanced remediation of simulated wastewaters contaminated with 2-chlorophenol and other aquatic pollutants by TiO2-photoassisted ozonation in a sunlight-driven pilot-plant scale photoreactor

Engineered nanomaterials for water treatment and remediation: Costs, benefits, and applicability

“…Similar to current techniques, photodegradation is one of the primary techniques for the treatment of halogenated organics by Me/MeO ENMs, and their large surface area to volume ratio gives them much higher reactivity than the bulk catalysts currently used. Both doped [273][274][275] and pure forms of TiO 2 [41,[276][277][278], as well as a fewer number of other materials [279,280], have been reported as effective photocatalysts for this class of pollutants. Photodegradation and dehalogenation have been shown to occur under a variety of water chemistries [278,[280][281][282] and lighting conditions [277,282,283], as well as in lab-scale and pilot-scale [277,282] reactors.…”

“…In addition, many nano-based technologies allow for reuse, often require lesser amount of space, can offer reduced toxic intermediate formation, and are adaptable to support the emerging concept of water treatment decentralization [10,11,500]. Many nano-based treatment technologies have been shown to perform well as complements to or substitutes for traditional treatment technologies [277,306,501].…”

Achievements and Trends in Photoelectrocatalysis: from Environmental to Energy Applications

“…Membrane-based systems are sometimes coupled to industrial treatment plants in order to evaluate the economic aspects of wastewater remediation [253]. As an example, Oyama and colleagues [254] have compared several advanced oxidation processes in wastewater remediation under solar irradiation. TiO 2 -photoassisted ozonation in a pilot plant scale photoreactor proved to be more promising than other techniques.…”

Eight-lamp externally irradiated bench-scale photocatalytic reactor: Scale-up and performance prediction

“…Marugan et al [26] recently simulated a bench-scale annular photoreactor with 1.25 L of irradiated volume, operating at optimum photocatalyst concentration by using a predictive procedure and kinetic data from a laboratory scale photoreactor (0.188 L). Furthermore, in recent years, special interest has been shown to extend the applicability of the kinetic models by using semi-empirical radiation methods, for bench to pilot-plant scale photocatalytic reactors [12,31,5].…”
