this study presents a review on advanced oxidation processes (aop) for simultaneous removal of no and so2. aop is based on using a strong oxidant such as ozone and h2o2 which is able to generate highly reactive intermediates. the pollutant will be oxidized and removed by these intermediates. in recent years, aop has been considered as an effective and attractive technology in the field of flue ...

The discoloration of a biologically pretreated waste water stream from a molasses processing by ozonation and two advanced oxidation processes (O3/H2O2 and 03/7-irradiation, respectively) was studied. Colour removal occurred with all three processes with almost the same efficiency. The main difference of the methods applied was reflected by the BOD increase during the discoloration period. By o...

introduction: advanced oxidation processes (aops) suggest a highly reactive, nonspecific oxidant namely hydroxyl radical (oh•), that oxidize a wide range of pollutants fast and non-selective in wastewater and water. materials and methods: in this work, the nitrogen-doped titanium dioxide nanoparticles were primed by sol-gel method, characterized by x-ray diffraction and scanning electron micros...

This study investigates the decomposition of clofibric acid (CLF) by different advanced oxidation processes (AOPs), such as UV (254nm), VUV (185 nm), UV / TiO2 and VUV / TiO2. The removal efficiencies of applied AOPs were compared in the presence and absence of dissolved oxygen. The removal efficiency of the studied AOPs towards degradation of CLF were found in the order of VUV / TiO2 + O2 > VU...

There is growing concern from the scientific community that pharmaceutical compounds are not treated sufficiently by current wastewater treatment methods and therefore trace amounts of such compounds are being identified in surface water, ground water and sewage effluents. Advanced oxidation processes (AOPs) are now being proposed for the specific treatment of industrial wastewaters and wastewa...

This research investigated the efficiency of Advanced Oxidation Processes, Enzymatic treatment, and combined enzymatic/AOPs sequences on color remediation of CMP pulp and paper mills effluent. Regarding enzymatic treatment two kinds of fungal enzymes; Laccase (EC: 1.10.3.2) from Terametes Versicolor and Versatile Peroxidase (EC: 1.11.1.7) from Bjerkandera adusta were chosen and applied. Also, t...

In this paper, a comparative study of the treatment of raw and biotreated (upflow anaerobic sludge blanket, UASB) textile dye bath effluent using advanced oxidation processes (AOPs) is presented. The AOPs applied on raw and biotreated textile dye bath effluent, after characterization in terms of COD, colour, BOD and pH, were ozone, UV, UV/H2O2 and photo-Fenton. The decolorization of raw dye bat...

Considering the nature of organic contaminants in water, methods their oxidative decomposition seem to be most appropriate for removal from contaminated water. There are a lot chemical oxidation, however, Advanced Oxidation Processes (AOPs) suitable technologies removal. AOPs belong group processes that efficiently oxidize compounds towards harmless inorganic products such as water or carbon di...
