A Novel Prototype Offset Multi Tubular Photoreactor (OMTP) for solar photocatalytic degradation of water contaminants

Abstract

OMTP solar photoreactor scheme (design using Sketchup®).

New aluminum mesh from recyclable material for immobilization of TiO2 in heterogeneous photocatalysis

“…In Figure 5B, the photo‐solar energy parameter was represented as a useful approach for the treatment of data obtained from real solar experiments using a relationship between experimental time and accumulated radiant power density . These results demonstrated the influence of the global solar irradiation on the photocatalytic degradation, in which the studied dye was completely degraded in the best system (solar/H 2 O 2 /TiO 2 ) after accumulated energy of 108 W · cm −2 was reached.…”

The Influence of Photocatalytic Reactors Design and Operating Parameters on the Wastewater Organic Pollutants Removal—A Mini-Review

“…The investigation done on floating and fixed-bed indicate the advantages of flotation, able to ensure uniform ZnO irradiation, which produce more oxidative radicals required for pollutant degradation. A high reactor volume (14.4 L) was tested for a comparative investigation regarding 4-chlorophenol and methylene blue (MB) removal [80]. The pollutant concentration was similar (10 mg/L) but the TiO 2 photocatalyst dosage varied from 0.25 for MB to 0.5 mg/L for 4-chlorophenol.…”

Comprehensive Kinetics of the Photocatalytic Degradation of Emerging Pollutants in a LED-Assisted Photoreactor. S-Metolachlor as Case Study

“…This model was used by Mueses et al [29] to analyze the effective radiation in a Compound Parabolic Collector photocatalytic reactor (CPC). Later, Ochoa-Gutiérrez et al [30] used the same model to simulate the solar radiation field in an Offset Multitubular Photoreactor (OMTP). Martín-Sómer et al [31] focused their efforts on evaluating the influence of the light distribution in an annular reactor provided with either Hg lamps or LEDs using Computational Fluid Dynamics (CFD).…”

“…R corr , λ Rcorr and Υ are SFM parameters that were computed exclusively from the photocatalyst scattering albedo, reactor optical thickness and scattering phase function, respectively [29]. The independent variable R p is the coordinate distance in the direction of the incident ray [30]. The incident radiation intensity was determined by Parker's actinometry based on the photochemical reduction of Fe(III) to Fe(II) from the ferrioxalate complex [45].…”
