Background and Aim: In this study, the removal of dye blue reactive-171 by combination of advanced oxidation processes UV/H2O2 and SBAR has been investigated. Methods: The efficiency of chemical and biological system was first investigated separately. In chemical system, the kind, power, initial dye concentration and hydrogen parasitize and in biological system, hydraulic detention time, aerati...
Oxidation processes can be used to treat industrial wastewater containing non-biodegradable organic compounds. However, the presence of dissolved salts may inhibit or retard the treatment process. In this study, wastewater desalination by electrodialysis (ED) associated with an advanced oxidation process (photo-Fenton) was applied to an aqueous NaCl solution containing phenol. The influence of ...
background: methyl tert -butyl ether (mtbe) has been commercially used as an octane enhancer to replace tetraethyl lead in gasoline since 1979. the high mobility, water solubility, and resistance to natural attenuation associated with mtbe may result in contamination of ground and surface waters. in this investigation the degradation of aqueous mtbe at relatively high concentrations was studie...
Introduction and purpose: Treatment of dye wastewater produced by textile industries is a major challenge for the environment. About 15% of the total produced dyes in the world are released in sewages during dyeing activities. Alizarin red S (ARS), a synthetic dye produced from Alizarin sulfonate is the most widely used dye in the textile industry. The aim of this study was ...
This paper explains the Fenton process – Advanced Oxidation Process for treatment of industrial waste water and effect of various parameters on Fenton process. AOPs are the process that generates the hydroxyl radical that oxidizes the impurity compounds and purifies the waste water. For generation of hydroxyl radical there are many methods are available. Fenton process is an advanced oxidation ...

Background & Objectives: Entering LAS through the wastewater plant’s effluent to water resources causes taste and odor changes, aquatics death, oxygen transfer limitation, and disorders in water treatment processes. Therefore, the study objective was to determine optimum conditions for fenton oxidation process to remove linear alkyl benzene sulfonate from aqueous environments using taguchi meth...
Introduction: Antibiotics as a type of pharmaceutical compounds are widely used in modern medicine and veterinary industries. They enter the environment in different ways, including agricultural runoff, direct discharge of urban wastewater treatment or human waste, direct disposal of medical, veterinary industrial waste and to name but a few. Antibiotics have been able to influence the microbia...
Fenton oxidation, an advanced oxidation process, is an efficient method for the treatment of recalcitrant wastewaters. Unfortunately, it utilizes H2O2 and iron-based homogeneous catalysts, which lead to the formation of high volumes of sludge and secondary pollutants. To overcome these problems, an alternate option is the usage of heterogeneous catalyst. In this study, a heterogeneous catalyst ...
