Advanced Oxidation Processes
Targeted Destruction of Refractory Contaminants with Precision Oxidation

Technology Overview

As industrial effluent grows increasingly complex, conventional treatment methods often fall short in removing micro-pollutants, pharmaceuticals and non-biodegradable organics. This is where Advanced Oxidation Processes (AOPs) play a vital role. Engineered to break down the toughest contaminants at a molecular level, AOPs are among the most effective advanced water treatment technologies available today.

Using powerful oxidants such as hydroxyl radicals, AOPs disrupt chemical bonds in persistent organic compounds, making them biodegradable or completely mineralized. Whether applied as a standalone solution or integrated into a larger system, AOPs enhance removal efficiencies, ensure regulatory compliance and enable sustainable reuse in high-risk sectors.

How it Works

AOPs combine strong oxidants and UV light, ozone and catalysts to produce hydroxyl radicals (·OH), which aggressively attack and degrade organic pollutants.

Core AOP Variants Include:

  • UV / H₂O₂: Ideal for degrading pharmaceuticals, pesticides and dyes
  • Ozone-based AOPs: Suitable for removing taste, odor and emerging contaminants
  • Fenton and Photo-fenton Reactions: Highly effective in treating leachates and chemical wastewater

FAQs

Unlike chlorine or ozone alone, AOPs generate hydroxyl radicals that react non-selectively and aggressively with complex organics, ensuring deeper and faster oxidation with minimal byproducts.

Yes. AOPs are often at the polishing stage in ZLD systems, where they ensure final COD / BOD reduction and remove residual refractory compounds prior to evaporation or crystallization.

AOPs are ideal for removing persistent organics such as pharmaceuticals, pesticides, colorants, surfactants and endocrine disruptors that cannot be effectively treated by biological systems.

Yes. Our AOP units are modular and can be designed for both small-scale applications and large continuous flows with capacities exceeding several MLDs.

AOPs can be inserted before or after biological stages or as a polishing unit. WOG ensures seamless integration with existing automation and compliance workflows.
