UV and ozone disinfection technologies have made significant strides in recent years. These methods use powerful light or gas to kill harmful microorganisms in air, water, and on surfaces. UV light at specific wavelengths can disrupt the DNA of pathogens, making them unable to reproduce or cause infections. New types of UV light show promise […]

Fenton reaction systems are powerful tools in chemistry. They use iron and hydrogen peroxide to create highly reactive molecules. These molecules can break down tough pollutants in water and soil. The Fenton reaction works best at a pH of about 3, which is lower than most natural soil conditions. This means it often needs some […]

Advanced Oxidation Processes in Wastewater Treatment: A Comprehensive Overview   Introduction   As the global demand for clean water continues to rise, effective wastewater treatment has become a priority for both developed and developing nations. Among the myriad technologies available for wastewater treatment, Advanced Oxidation Processes (AOPs) have emerged as a promising solution due to […]

Electrochemical Advanced Oxidation Processes (EAOPs) have gained a lot of attention in recent years for their potential applications in water treatment and pollution control. These processes use electricity to generate reactive oxygen species (ROS) that can degrade organic pollutants in water. In this article, we will discuss the principles, mechanisms, and applications of EAOPs, as […]

Ultraviolet (UV) light combined with hydrogen peroxide (H2O2) is an advanced oxidation process (AOP) that holds significant promise for the treatment of wastewater. By harnessing the power of UV light to activate H2O2, this method produces hydroxyl radicals, which are highly reactive species capable of breaking down a wide range of contaminants, from organic compounds […]

The Fenton process is an advanced oxidation procedure that harnesses the chemistry of iron and hydrogen peroxide to purify wastewater. It is named after the British chemist H.J.H. Fenton, who discovered that ferrous ions could catalyze the decomposition of hydrogen peroxide to generate hydroxyl radicals, potent oxidants capable of degrading a wide range of organic […]

Advanced Oxidation Processes (AOPs) are a cornerstone technology in modern wastewater treatment methodologies. Characterized by the generation of highly reactive species, particularly hydroxyl radicals, AOPs are designed to address complex and otherwise persistent pollutants in wastewater streams. These reactive species can break down a diverse array of contaminants, from organic compounds to pathogens, thereby reducing […]
