Ferrous ion-based catalysts have been widely employed to oxidatively destruct the major industrial pollutants such as phenolic compounds through advanced oxidation processes (AOPs). These agents, however, inevitably show several drawbacks including the need for pH adjustment and further purification steps to remove residual salts. Here we report the use of a chemical vapour deposition (CVD) gra...

Microplastics are generated from plastic waste in landfills due to physical, chemical, and biological effects, eventually enter into the leachate. Leachate is a potential source of environmental microplastics which has not been emphasized. Here, we summarized investigation leachate 9 countries 28 papers, provided comprehensive review sampling, detection, separation leachate, elaborated on quali...

Contaminants of emerging concern (CECs) constitute a wide class organic molecules, which are found dissolved in wastewaters. Chemical properties CECs as their chemical structures; nevertheless, most the can be removed from wastewaters using Advanced Oxidation Processes (AOPs). However, there examples that have proven recalcitrant to AOPs. In such cases, Reduction (ARPs) include those techniques...

Antimicrobial resistance (AMR) is a serious problem for modern society, not only associated with clinical environments, but also the natural environment. Conventional wastewater treatment plants (WWTPs) are important nodes dissemination of antibiotic to aquatic environment since they reservoirs antibiotic-resistant bacteria (ARB), genes (ARGs), and residues. WWTPs designed remove these determin...

Abstract The tannery industry plays a significant role in the economy but poses severe environmental threat due to its high water and chemical usage, leading wastewater generation with concentration of pollutants. This contains range contaminants created throughout leather manufacturing process, making effluent disposal challenge for industry. tanning process also contributes significantly pH, ...

Ultraviolet advanced oxidation processes (UV-AOPs) were compared using sodium perborate (UV/NaBO3 AOP) or hydrogen peroxide (UV/H2O2 for 1,4-dioxane removal from tertiary wastewater effluent. Both UV-AOPs also tested with the addition of acetic acid. Results revealed that performed similarly to peroxide. The UV/NaBO3 AOP 6 milligrams per liter (mg/L) as H2O2 resulted in 43.9 percent removal, wh...

The domestic use and industrial activity, especially in developing countries, produce large amount of wastewater. This wastewater when disposed into natural channels may lead to high pollution risk. There are different methods for wastewater treatment. One of them is Advanced Oxidation Processes (AOPs), still it has some limitations. The present work has been concentrated on the degradation of ...

Water scarcity and water pollution is a worldwide problem and has driven research into eco-friendly and low-energy cost efficient remediation. The reuse of wastewater for non-potable purpose after proper treatment is the only sustainable solution to the problem. Advanced oxidation processes (AOP) based on the in-situ generation of hydroxyl radicals have been intensively investigated for this pu...

studied. The experiments were carried out under various UV light intensities and reactor dimensions to investigate and compare the removal efficiency of the pollutant and the mineralization and dechlorination of organic intermediates by photolysis and advanced oxidation processes (AOPs). A photoreactor design equation for the photolysis of gaseous TCE in air streams by the 254 nm UV irradiation...
