Research on Photocatalytic Wastewater Treatment Reactors: Design, Optimization, and Evaluation Criteria

Photocatalytic wastewater treatment technology has been proposed for more than 30 years, but it is still seldom used in industry. The lack of research on high-performance and cost-effective photocatalytic reactors (PWTRs) may be one the major reasons limiting industrial application technology. To accelerate realization application, this review emphasizes importance increased PWTRs. In review, we analyze role treatment, followed by a comprehensive discussion PWTR design from multiple perspectives, including photocatalyst selection, loading recovery method photocatalysts within reactor, light source design, reaction conditions control. Additionally, consider cost reactor design. Finally, summarize optimization strategy PWTRs criteria evaluating performance. main innovation lies analysis with focus solutions to promote use
