UV/H₂O₂ has become the preferred mainstream technology for removing taste & odor compounds (2-MIB, GSM), pesticides, endocrine disruptors and DBPs precursors. The trend is shifting to UV-LED instead of traditional mercury lamps for smaller size, longer service life, lower energy consumption and no mercury pollution.
Optimization of O₃/UV and O₃/H₂O₂ focuses on controlling bromate formation in bromide-containing water sources, supported by catalytic ozonation and precise dosing with pH adjustment.
Development of non-radical pathways (singlet oxygen, high-valent metals, sulfate radicals) to reduce ineffective reactions with natural organic matter and improve energy efficiency.
Deep coupling of AOP + activated carbon (GAC/ACF) + membrane filtration (UF/RO) to form a closed loop of oxidation–adsorption–separation.
Synergy between AOP and biological treatment: AOP breaks down refractory organics into biodegradable small molecules, reducing AOP load and chemical/energy consumption.
Combined AOP systems to enhance degradation rate and adapt to wider water quality conditions.
Solar-driven AOPs using visible-light-responsive catalysts and PV-powered UV-LED systems for distributed and emergency water supply.
Metal-free or low-metal catalysts (graphene, activated carbon) to avoid metal leaching and secondary pollution.
Optimization of reactor design and dosing strategies to reduce energy consumption by 20%–40% and chemical costs by over 30%.
AI-assisted real-time monitoring and automatic control based on online sensors (UVT, TOC, pH, ORP) to automatically adjust UV intensity and oxidant dosage.
Modular and skid-mounted equipment for rapid deployment in old plant reconstruction, emergency water supply and small-scale water supply stations.
Digital twin and remote operation & maintenance for fault early warning and improved reliability.
AOPs have become a standard configuration in advanced treatment of municipal water plants to address emerging pollutants, odor and disinfection byproducts.
Popularization in distributed and small-scale systems for residential buildings, rural centralized water supply and commercial water purification.
Widely used in emergency response, bottled water production and desalination pretreatment for rapid degradation of toxic organic pollutants.
Reducing total cost of ownership through integration, intelligence and green energy.
Precise control of bromate and intermediate byproducts.
Improving catalyst stability and recovery via immobilization and magnetic separation technology.
