Based on a synergistic digestion method of ultraviolet combined with ozone (UV/O3), this article investigates the reaction characteristics nitrogen-containing compounds (N-compounds) in water and influence ions efficiency. In respect, novel efficient AOPs-based dual-environmental for determination total dissolved nitrogen (TDN) waters complex components is proposed, hopes improving detection ef...

The use of conventional water and wastewater treatment processes becomes increasingly challenged with the identification of more and more contaminants, rapid growth of population and industrial activities, and diminishing availability of water resources. Three emerging treatment technologies, including membrane filtration, advanced oxidation processes (AOPs), and UV irradiation, hold great prom...

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...

Solar assisted Photo Fenton was compared with advanced oxidation processes for their color and COD removal efficiency and cost effectiveness. H2O2 alone appeared to be inefficient to reduce color and COD content of any effluent. The performance of Fenton process was slightly better, color and COD removals were 45 % and 63% respectively. Photo Fenton treatment of blue effluent resulted into colo...

This research was focused on the investigation of the efficacy of advanced oxidation processes (Fenton, ozonation and UV/H2O2) for decolorization of reactive azo dye (Blue CL-BR) using bleach wastewater as possible source of H202. All the experiments were performed on the laboratory scale set-up. The results showed that colour removal efficiencies by UV or bleach (H2O2) alone were not so effici...

In recent years, the removal of pharmaceutical and personal care products (PPCPs) from aqueous solutions has been gaining a lot attention researchers throughout world. This is particularly due to concern about their potential hazards toxicities, as they are classified emerging contaminants. Thus, there an increasing need investigate technologies for PPCPs at deeper more holistic level. review a...

background: titanium dioxide (tio2)-mediated photocatalysis has been found to be an efficient method of water treatment and is capable of degrading a wide range of organic pollutants and microbial agents with high efficiency. the microorganism pseudomonas aeruginosa is resistant to chemicals and uv irradiation. bacteria which are resistant to uv-induced oxidative damage of the cell membrane are...

The extensive use of pharmaceuticals and personal care products (PPCPs) causes high concentrations pharmaceutical metabolites to exist in aquatic environments. Though the removal parent PPCPs has raised concerns, degradation was rarely investigated. In this study, 4-acetylaminoantipyrine (4-AAA), a typical dipyrone metabolite frequently detected worldwide surface water wastewater, initially stu...
