Research Directions for Promoting Applications of Advanced Oxidation Processes in Water Remediation.

Area of Science:

• Environmental Science
• Chemical Engineering
• Water Treatment Technologies

Background:

• Advanced oxidation processes (AOPs) are crucial for mitigating water pollution impacting ecosystems and human health.
• Decades of laboratory research show AOPs' decontamination potential, yet large-scale implementation remains hindered.

Purpose of the Study:

• To identify the gap between AOP research and engineering requirements.
• To propose strategies for accelerating the practical application of AOPs in water remediation.

Main Methods:

• Analysis of discrepancies in catalyst application, reactor design, byproduct management, treatment targets, and operational conditions.
• Evaluation of emerging strategies: precise oxidation, sustainable system design, machine learning, and resource recovery.

Main Results:

• Significant mismatches exist between research priorities and engineering needs, impeding AOP scale-up.
• Emerging strategies offer promising avenues for optimizing AOP implementation.

Conclusions:

• A shift towards engineering-oriented research is necessary to overcome AOP implementation bottlenecks.
• Enhanced collaboration between research and engineering is vital for deploying AOPs in real-world water treatment.
