Currently, the textile industry is one of the most important economic sectors in many countries. Besides, it is known as a major consumer of water and consequently one of the largest groups of industries causing intense water pollution. Chemicals, including surfactants, dyes, resins, dispersants agents, inorganic salts, etc., play a variety of functions during the textile processing and are pre...

It is a long-pursued goal to develop electrified water treatment technology that can remove contaminants without byproduct formation. This study unveiled the overlooked multifunctionality of electro-Fenton (EF) and induced EF (I-EF) processes organics, pathogens, phosphate in one step halogenated The I-EF used sacrificial anode or an electrode generate Fe2+ activate H2O2 produced from gas diffu...

In this study, the applicability of factorial design to treatment greywater (GW) containing dodecyl-benzene sulfonic acid (LAS) by electrochemical advanced oxidation processes (EAOPs) is demonstrated. At bench scale, anodic with electrogenerated H2O2 (AO-H2O2) and photoelectro Fenton (PEF) were studied following a 23 central point insertion, using first-order mathematical polynomial. former pro...

Advanced oxidation procedures (AOPs) refer to a variety of technical that produce OH radicals sufficiently oxidize wastewater, organic pollutant streams, and toxic effluents from industrial, hospital, pharmaceutical municipal wastes. Through the implementation such procedures, (post) treatment waste leads products are more susceptible bioremediation, less possess load. The basic mechanism produ...

At present, the use of conventional wastewater processes is becoming increasingly challenging, mainly due to presence biorecalcitrant organic matter. Advanced oxidation such as Fenton, Fenton-like and hybrid have been successfully employed for treatment highly concentrated toxic non-biodegradable pollutants. Here, a series bimetallic catalysts, based on Cu/Fe supported over ZrO2, were investiga...

The effects of ultrasonic irradiation, the chelating agent modified Fenton reaction, and a combination of ultrasound and the Fenton method in removing petroleum contaminants from a soil were studied. The results showed that the contaminant removal rate of the Fenton treatment combined with an oxalic acid chelating agent was 55.6% higher than that without a chelating agent. The average removal r...

A novel electro-Fenton (E-Fenton) process was developed, in which the desired pH for an effective E-Fenton reaction and for a neutral treated media could be obtained by utilizing the reaction-released H+ and OH- in stead of chemical addition. In the laboratory-scale process using three chambers, the substrate solution pH > 4.0 was designed to be adjusted in situ through three sequencing steps: ...
