Photocatalytic oxidation/ozonation of a mixture eight pharmaceuticals added to secondary effluent, SE, an urban wastewater treatment plant has been studied using TiO2 supported on commercial Al2O3/SiO2 ceramic foams. As radiation source UVA LEDs (365 nm) or solar was used. Pharmaceuticals were at high (1 mg L−1 each) relatively low (50 μg concentration, contributing 25% and 1.5% the initial TOC...

Abstract This work aims to identify the best treatment condition for removal of chemical oxigen demand (COD) and increase biodegradability in an advanced oxidative process photocatalytic ozonation with titanium dioxide (TiO2), applied remediation leachate produced at municipal landfill Campo Mourao, Parana. The experiment was carried out using a chamber system based on corona effect. A statisti...

Abstract Iran's most important iron ore mine is located in the central region, and because of water shortage this area, need to reuse effluent from essential. On other hand, there are no suitable conditions for treating large volumes Iran. For reason, produced should be reduced returned consumption cycle by using appropriate technology. This study aimed investigate ozonation/lime effect on poly...

Abstract This research emphasized the importance of removing organic pollutants from wastewater discharges. In this review, different advanced oxidation processes are discussed. A broad classification was used for treatment. An overview TiO2-based photocatalysis, Fenton process, and photocatalytic ozonation has been done. The mechanism methods studied. advantages limitations these also Various ...

Water pollution is a globally recognized serious problem that hindering human development and societal progress. One of the most feasible methods to eliminate this wastewater treatment reuse. Emerging micropollutants, such as pesticides, are notorious for not being removed using traditional methods. Therefore, novel techniques advanced oxidation processes (AOPs) have been proposed, among which ...

Graphitic carbon nitride (g-C3N4) is a promising catalyst for contaminants of emerging concern removal applications, especially as visible-light-driven material. In this study, g-C3N4 catalysts were effectively synthesized through simple thermal polymerization method, using melamine, urea, and thiourea precursors to elucidate the influence these compounds on final product’s photocatalytic perfo...

More effective techniques are required to mineralize the increasing number of recalcitrant organic contaminants at low concentrations in the water environment using advanced oxidation process. Though relatively new, photocatalytic ozonation (O3/UV/TiO2) is considered superior to ozonation (O3) and photocatalysis (UV/TiO2), due to synergistic effects and use of immobilized TiO2 photocatalysts is...
