UV-AOP systems combine ultraviolet irradiation, oxidant dosing and advanced oxidation technology to generate hydroxyl radicals for destroying persistent organic pollutants. Furthermore, by optimizing equipment design, manufacturing processes and engineering services, our UV-AOP solutions aim to provide approximately 60% investment cost compared with similar European solutions. At the same time, the system maintains around 80% of the core treatment performance and technical service capability.

UV-AOP System Structure and Core Components
A complete UV-AOP system consists of four major modules: UV reactor, oxidant dosing system, online monitoring system and automatic control unit.
The UV reactor is the core oxidation component. It includes UV lamps, quartz sleeves, reaction chambers and safety protection systems. The reactor design directly affects UV intensity distribution, treatment efficiency and operating stability. According to wastewater characteristics, engineers select suitable UV power, reactor quantity and hydraulic retention time.
Moreover, the oxidant dosing system works together with UV irradiation to generate hydroxyl radicals. The dosage of hydrogen peroxide or other oxidants depends on COD concentration, pollutant type and required oxidation level. In addition, proper chemical control can improve treatment efficiency. At the same time, it can reduce unnecessary operating costs and improve overall system economics.
The automatic control system integrates flow monitoring, UV intensity detection and water quality analysis. Similar to European industrial UV-AOP solutions, intelligent control allows the system to adjust operating parameters according to actual pollutant loading, improving stability and reducing manual operation requirements.
UV-AOP Technical Sizing for Industrial Wastewater Treatment
Selecting a UV-AOP system requires detailed analysis of wastewater conditions. The main parameters include flow rate, COD concentration, pollutant composition, UV dose and oxidant demand.
For high-load wastewater, COD concentration is one of the most important factors. Pharmaceutical, chemical and pesticide wastewater often contains toxic and persistent organic compounds that cannot be treated effectively by conventional biological processes alone.
A practical example comes from Enviolet’s pharmaceutical wastewater application. In an antibiotic API production project, the wastewater contained COD concentrations of approximately 60–75 g/L and highly toxic organic compounds. The installed UV-AOP system reduced antibiotic-active compounds by around 4,800 kg per day, allowing the treated water to continue through biological treatment.
Based on this type of industrial application experience, our UV-AOP systems focus on achieving similar engineering objectives through optimized design. By using modular reactor structures, localized manufacturing and efficient supply chains, the target investment cost is approximately 60% of comparable European solutions, while maintaining around 80% of the core oxidation performance.
Case Study: Improving Biodegradability of High-COD Wastewater
Enviolet has also applied UV-AOP technology for improving the biodegradability of difficult industrial wastewater. One published application treated up to 360 m³/day wastewater with COD levels up to 45 g/L before biological treatment. The AOP process improved wastewater characteristics and helped maintain stable operation of the downstream biological system.
Following the same application principle, our UV-AOP solutions are designed for industries including pharmaceuticals, chemicals, pesticides and specialty manufacturing. The system can be used as a pretreatment process to reduce toxicity, improve biodegradability and protect biological treatment units.
Maintenance and Service Comparison
Furthermore, long-term system performance depends not only on equipment quality but also on engineering support and maintenance services. Therefore, a complete service system is essential for stable operation throughout the equipment lifecycle.
European suppliers such as Enviolet provide services including feasibility studies, laboratory testing, turnkey AOP plant delivery, commissioning support and long-term maintenance assistance.
Our service strategy follows a similar engineering approach. Customers receive wastewater analysis support, equipment sizing recommendations, installation guidance, commissioning assistance and operation optimization.
Although the investment cost is optimized to approximately 60% of comparable European solutions, the service target remains at around 80% of the original European service capability. Through local engineering teams and faster communication channels, customers can receive technical support with shorter response times.
