In this study, the photocatalytic ozonation process using either UV lamps with a wavelength close to a solar wavelength (UVsolar) or natural solar light was established to study the effects of the major operating parameters on the removal of a toxic disinfection by-product (DBP), dichloroacetonitrile (DCAN), from drinking water. Based on the test results of a bench system, the UVsolar/TiO2/O3 p...

Abstract The growing contamination of various freshwater resources due to industrial effluent is a serious concern among the scientific community. Several organic compounds are essentially used as chemical intermediate in variety processes. These hazardous chemicals which already considered dangerous global public health and other forms life their high toxicity, carcinogenicity. contaminants fo...

Industrial and other anthropogenic activities lead to increase in persistent organic pollutants (POPs) natural water bodies. POPs are harmful not only the aquatic ecosystem but also human health. Researchers around globe have been working develop efficient, cost-effective, environmentally-friendly methods for treatment of contaminated waters. The chapter basically focuses on removal by catalyti...

The present study was conducted in order to investigate the efficiency of different advanced oxidation processes both individually and combination with biological method for removal color chemical oxygen demand (COD) from wastewater pulp paper industry. Advanced include ozone, Fenton, hydrogen peroxide, photo-Fenton. Biologically treated successively subjected (AOPs). optimum conditions ozone t...

background: electrochemical methods, as one of the advanced oxidation processes (aops), have recently been applied to remove different contaminants from water and wastewater. this study compares the performance of anodic oxidation (ao) and electro-fenton (ef) methods on waste sludge treatment. methods: this experimental study was performed on real sludge and the effect of operating parameters s...

The removal of dyes from wastewater, is one of the major environmental concerns due to their high color density, and they are toxic at even low concentrations. Adsorption process by advanced oxidation processes (AOPs) has been found to be a more effective method than classical methods for treating dye-containing wastewater. This research, is to investigate the decolorization abilities of az...

Bisphenol A (2,2-bis(4-hydroxyphenyl)propane), a chemical compound used in the manufacture of polycarbonate, epoxy and polysulfonate resins, can alter the endocrine system, causing adverse effects in the reproductive systems of humans and animals. More recently, the application of advanced oxidation processes (AOPs) has been recommended to treat toxic and/or biorefractory compounds including BP...

Spectrophotometric examinations showed the presence of phenolic compounds in the organic residue collected from four groundwater resources located in vicinity of an oil refinery at the outskirt of Tehran. The average concentration of total phenolic compounds was about 0.38 mg.L-1 in these samples using Folin-Ciocalteu method. GC-Mass analysis disclosed that alkylphenols were the major phenolic ...

The aim of the study was to investigate decolourization Methylene Blue (MB) in aqueous solution using advanced oxidation processes (AOPs) and biosorption comparatively. Photocatalytic MB studied TiO2 as catalyst. photocatalytic by direct UV irradiation alone, only TiO2/UV investigated. It found that process increased with decreasing pH, rate also presence when compared alone. Decolourization Fe...
