Engineering and modeling perspectives on photocatalytic reactors for water treatment

• Modeling and design criteria of photocatalytic reactors for water treatment Sunlight artificial radiation sources analyzed Pilot full-scale demonstrated Photocatalytic system process economics The debate on whether photocatalysis can reach full maturity at commercial level as an effective economical purification wastewater has recently intensified. Despite a bloom scientific investigations in the last 30 years, particularly with regards to innovative materials, so far seen few industrial applications. Regardless points view, it been realized that research reactor modeling are now equally urgent match extensive carried out materials. In reality, development advanced steadily terms over two decades, though this topic captured smaller specialized audience. critical review, we introduce latest developments from engineering perspective. focus is pilot- or greater scale. utilizing both natural sunlight UV irradiation comprehensively discussed. most promising photoreactor designs models examined giving key guidelines. Other considerations, such operation, cost analysis, patents, several applications also presented. dissemination principles among community industry currently one greatest obstacles translating PWT into widespread real-world application.
