Advanced oxidation reaction is where oxidizer like ozone or peroxide of hydrogen is decomposed by the reaction with the UV, to produce OH-radical with strong oxidizing power to have oxidation dissolution in contamination substance, and is a water treatment techniques that can eliminate synthetic detergent, agricultural pesticides in a short period of time, that was not easily disassembled by conventional biological processing methods.

Interest and demand about advanced oxidation reacting technology is rising because non-degradable materials that is included in the environmental hormone, which has high toxicity and cancer-generating characteristic, are classified as specific quality of water toxic chemical substance and it is particularly managed with emission permitting density perspectively.

Advanced oxidation reacting device within advanced oxidation reacting technology has drawbacks as control of process is complex because its' reacting type is gas-liquid reaction, low water solubility of ozone, vital use of high capacity of ozone generator and oxygen generator, and difficulties in management. But because convergent efficiency of ozone to OH-radical by UV is high, no waste-generating in the reaction, and no consuming side-effect that ozone re-react with OH-radical, it is being used alot in the industry.

Otherwise, advanced oxidation reaction using hydrogen peroxide is liquid-liquid reaction, which has relatively simple construct and is possible to operate intermittently and do unmanned-operation due to the easy operation compared to the reaction of ozone and UV, and ozone and hydrogen-peroxide, a gas-liquid reaction. But because reaction efficiency is considerably low compared to other advanced oxidation reaction, and economically infeasible, commercialization is almost not undertaken.

Hydrogen peroxide and UV’s advanced oxidation reacting system of S&P environment minimize the side effect consumed when generated OH-radical doesn’t participate in waste substance decomposition reaction, and react with the non-reacted hydrogen peroxide around. As a result, it is more compact compared to other advanced oxidation reacting device because it can maximize the efficiency of the advanced oxidation reaction disassembling waste material, and commercialized its’ strength of easy operating and management.
