This document discusses advanced oxidation processes (AOPs) for water treatment and wastewater. AOPs involve generating strong oxidizing agents like hydroxyl radicals that react with organic contaminants in water. There are several AOP technologies including ozone/ultraviolet irradiation, hydrogen peroxide/ultraviolet irradiation, and Fenton's reaction. While AOPs have been implemented in some industries, their commercial use is still limited due to relatively high costs. The document provides examples of different AOP technologies and references for further information.

2. Background
Nowadays, organics wastes are more
difficult to be degraded by microbiological
or membrane filtration, and albeit in very
small concentrations content (ppm / ppb)
like, compound dioxin, furan, and atrazine.
There is an invention of a liquid waste
treatment technology which utilizes
oxidation method using ozone gas. This
techology is combined with ultraviolet light
and known as Advanced Oxidation Process
(AOP)
Compound dioxin Furan
Hence,

3. 1. The formation of strong oxidants
(e.g., hydroxyl radicals)
Principle
AOPs involve the two stages of oxidation :
2. The reaction of these oxidants with
organic contaminants in water
Technology Applied
AOPs can be divided into:
• Hydrogen
Peroxide/Ozone (H2O2/O3)
• Ozone/Ultraviolet
Irradiation (O3/UV)
• Hydrogen Peroxide/
Ultraviolet Irradiation
(H2O2/UV)
• High Energy Electron
Beam Irradiation (E-
beam)
Emerging Technologies
• Cavitation (Sonication
& Hydrodynamic)
• TiO2-catalyzed UV
Oxidation
• Fenton’s Reaction
Established Technologies

4. Example of Technology Applied

Example of Hydrogen Peroxide/ Ultraviolet
Irradiation (H2O2/UV)

5. implementation
AOPs still have not been put into commercial use on a large scale (especially in
developing countries) because of the relatively high costs. There are roughly 500
commercialized AOPs installations around the world at present, mostly in Europe and the
United States. Other countries like China are showing increasing interests in AOPs.
AOP has been imlemented in
drinking water industry, and the
other industry as waste water
technology
