This skid-mounted thermally activated Advanced Oxidation Process (AOP) system was engineered for a chemical wastewater treatment project requiring deep COD reduction and removal of refractory organic compounds.

In chemical water treatment applications, operators often ask what technologies can further reduce COD when biological systems reach their limits. Advanced oxidation processes are widely adopted for this purpose due to their ability to generate hydroxyl radicals with extremely high oxidation potential.

How Does the Advanced Oxidation Process Work?

The AOP system generates hydroxyl radicals (·OH), which rapidly break down complex and non-biodegradable organic molecules. These radicals can significantly improve biodegradability or achieve direct pollutant removal in industrial wastewater streams.

This unit utilizes thermal activation to enhance hydroxyl radical generation under controlled conditions. Compared with simple oxidant dosing, thermally activated AOP can improve reaction efficiency while maintaining operational stability. Clients frequently compare AOP with ozone oxidation or Fenton systems; this configuration provides a balanced approach between efficiency, controllability, and engineering reliability.

Skid-mounted Design and Engineering Integration

The system is delivered as a skid-mounted modular unit integrating the reactor, dosing system, temperature control components, piping, valves, and control interfaces. Skid-mounted AOP systems are often preferred in chemical wastewater projects where construction time is limited or space is constrained.

Equipment sizing and material selection were determined based on wastewater characteristics, flow rate, COD concentration, and operating parameters. This addresses common questions such as how to select an AOP system for chemical wastewater and how to ensure compatibility with existing treatment lines.

Operational Stability and Maintenance Considerations

Operational reliability is a primary concern in chemical wastewater treatment plants. The structural layout allows maintenance access and routine inspection, while process control ensures stable oxidation performance and reduced fluctuation risks.

Typical Applications

This thermally activated AOP system is suitable for:

Chemical industry wastewater containing refractory organics

Industrial wastewater requiring deep COD removal

Pre-treatment or polishing stages in integrated treatment systems

Improving biodegradability prior to biological treatment

The skid-mounted thermally activated Advanced Oxidation Process (AOP) system represents an engineered solution for complex chemical wastewater treatment scenarios, combining hydroxyl radical oxidation technology with modular system integration for practical industrial deployment.
