The objective of this study is to summarize studies and investigations about advanced oxidation processes (AOPs) used for the treatment of petroleum wastewater, which mainly contained oil, organic matter and other compounds. The big difference was shown in the specification of wastewater among the...

This report was aimed at an investigation of efficiency for Photochemical Advanced Oxidation Processes (UV photolysis, UV/H2O2, UV/TiO2, UV/H2O2/TiO2 and UV/H2O2/Fe2+ processes) to decolorize Malachite Green Oxalate (MGO) dye. Experimental runs were performed using laboratory scale photochemical...

This review provides a general overview of the application of chemical oxidation to hydrophobic contaminants in the form of non-aqueous phase liquids (NAPLs). Three types of chemical oxidation processes, conventional activated persulfate, permanganate, and ozonation, along with three advanced...

In this study, it was studied various advanced oxidation treatment processes; Fenton, UV/H2O2, UV/O3/H2O2 for treatability of hospital wastewaters containing antibiotics (cephalosporines). Taguchi’s L25 orthogonal array design was applied to design of advanced oxidation processes, for simplification...

Presence of antibiotics in the environment specially in aqueous environments is considered a major warning about health and environment. Thus, this study aims the efficiency of coupled process of Activated Carbon (AC) prepared from mango seed+ZnO under UV irradiation as an advanced oxidation process...

Three different advanced oxidation processes (AOPs) were applied to investigate the removal of emerging contaminants (ECs) i.e. sulfamethoxazole (SMX), diclofenac (DCF) and carbamazepine (CBZ) in synthetically prepared solutions. The degradation of these substances was carried out by ozonation...

Treatment of tannery effluent is a key issue that requires novel research. The presented work is an attempt to carry out advanced oxidation process in a Multi-orifice Oscillatory Baffled Column using ozone as oxidizer and compare the extent of treatment with sono-catalytic treatment with TiO2 as...

This work focuses on the use of carbon-coated magnetic cobalt ferrite nanoparticles as catalysts for catalytic wet peroxide oxidation (CWPO) of the emerging concern pollutant paracetamol (PCM). The magnetic core of the catalyst is composed of CoFe2O4 developed by a sol-gel method. The core is...

In this work, the effectiveness of electro-Fenton process degradation of sodium dodecylbenzene sulfonate (SDBS) anionic surfactant in acidic wastewater was investigated. Taguchi method was applied to study the effect of process parameters on oxidation of SDBS pollutant. An orthogonal array L 9...

The objective of this study is to summarize studies and investigations and show a brief details of different technologies used for the treatment of petroleum wastewater. The wastewater from Petroleum industries and refineries mainly contains oil, organic matter and other compounds. The treatment of...

Anthracene and phenanthrene belong to a group of persistent environmental contaminants called PAHs. Evaluation of the structure of two selected PAHs i.e. anthracene and phenanthrene on their resistance to destruction by UV-activated PDS was the aim of this study. The authors focused on two aspects...

The photocatalytic oxidation of organic and petroleum wastewater treatment is an advanced oxidation process (AOP) with several benefits. It operates at normal temperatures and pressure, is inexpensive, does not produce secondary waste, and us easily accessible. Many studies have employed bubble...

Catechol is used as an antioxidant, fungicide, and polymerization inhibitors in a variety of industries such as petrochemical. Catechol must be removed from effluents before it enters to environment. This study aimed to investigate combined UV radiation and persulfate process in removal of catechol...

Poultry slaughterhouse wastewater (PSWW) is a crucial concern fundamentally due to extensive generation and related substantial amounts of recalcitrant organic content due to high COD and oil and grease (O&G) levels. Hybrid advanced oxidation processes are promising, green, and innovative options to...

250 million people worldwide suffer from visual impairment. 64% of them wear glasses. More than 80 percent of all eyeglasses worn today have plastic lenses. Plastic lenses made of polycarbonate discs are created through the process of machining which requires the use of a coolant. The ensuing...

Solar simulated heterogeneous photocatalysis (SSHP) with suspended TiO 2 was investigated in the inactivation of tetracycline resistant/sensitive Enterococcus (TRE/TSE) strains in the effluent of an urban wastewater treatment plant (UWTP). The effect of solar simulated disinfection (SSD) on the...
