In chemical oxidation, an oxidising agent is added to the wastewater. Electrons travel from the oxidant to the pollution, modifying the structure of pollutants in the water, and making them less harmful. Advanced oxidation is a further step for removing organic compounds that might result as a byproduct of the chemical oxidation process.
