Abstract : This paper presents a comprehensive review of advanced oxidation processes (AOPs) as a vital component of water treatment technologies aimed at addressing pollution challenges and ensuring water safety. AOPs involve the generation of highly reactive hydroxyl radicals to degrade a wide range of organic and inorganic contaminants in water. Various AOPs, including photocatalysis, ozonation, and electrochemical oxidation, are discussed in detail, highlighting their mechanisms, advantages, limitations, and recent advancements. Furthermore, the paper explores strategies for enhancing the efficiency and applicability of AOPs, such as process optimization, reactor design, catalyst development, and hybrid systems. Case studies and practical examples are provided to illustrate the effectiveness of AOPs in treating different types of water pollutants. Overall, this review aims to provide insights into the current state-of-the-art in AOPs and their potential for sustainable water treatment solutions.
Keywords: Water treatment, Advanced oxidation processes, Photocatalysis, Ozonation, Electrochemical oxidation, Reactor design, Process optimization, Catalyst development.
