Electro-oxidation (EO or EOx), also known as anodic oxidation or electrochemical oxidation (EC), is a technique used for wastewater treatment, mainly for industrial effluents, and is a type of advanced oxidation process (AOP). [1] The most general layout comprises two electrodes, operating as anode and cathode, connected to a power source.

A goal of the wastewater purification by means of AOP procedures is the reduction of the chemical contaminants [7] and the toxicity to such an extent that the cleaned wastewater may be reintroduced [8] into receiving streams or, at least, into a conventional sewage treatment. Although oxidation processes involving ·OH have been in use since ...
In plasma electrolytic oxidation, higher potentials are applied. For example, in the plasma electrolytic oxidation of aluminum, at least 200 V must be applied. This locally exceeds the dielectric breakdown potential of the growing oxide film, and discharges occur. These discharges result in localized plasma reactions, with conditions of high ...
Location of Egypt. Egypt is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula.Egypt's economy depends mainly on agriculture, media, petroleum imports, natural gas, and tourism; there are also more than three million Egyptians working abroad, mainly in Saudi Arabia, the Persian Gulf and Europe.
These treatment processes are dubbed Advanced oxidation processes, and are key in destroying byproducts from disinfection, pesticides, and other hazardous compound. There is an emerging effort to enable these processes to destroy more tenacious compounds, especially PFAS [ 44 ]

Fenton's reagent is used as a sewage treatment agent. [20] Fenton's reagent can be used in different chemical processes that supply hydroxyl ion or oxidize certain compounds: [citation needed] The first stage of Fenton's reaction (oxidation of Fe 3+ with hydrogen peroxide) is used in Haber–Weiss reaction
