Electrocoagulation (EC) in a batch cell with Al anode and Fe cathode in monopolar parallel (MP) connection was used for the removal of basic dye, Bromophenol Blue (BPB). The effects of current density, pH, temperature and initial dye concentration, on the process were investigated. Equlibrium data were analyzed using four model equations: Langmuir, Freudlinch, Temkin and Dubinin–Radushkevich. D...

Accumulation of large quantity of non-biodegradable textile dyes into the environment made much attention to finding a suitable solution for the degradation of textile dyes. In this present study, decolorization efficiency of two different treatment technologies such as Photo-Assisted Chemical Oxidation (PACO – UV/H2O2) and Electrocoagulation (EC) on Reactive ...

The abundant presence of fluoride (F-) in surface water bodies is an environmental concern because its effects on human health; medical reports confirmed that intake above 1.5 mg/L leads to many health complications, including but not limited weak bones and enamel fluorosis. Thus, the World Health Organisation (WHO) defines 1.20 as maximum permissible F- concentration drinking water. electrocoa...

Electrochemical ferrous iron (Fe2+) wastewater treatment is gaining momentum for treating municipal due to its decreasing costs, environmental friendliness and capacity removal of a wide range contaminants. Disinfection by electrocoagulation (Fe-EC) has been occasionally reported in full scale industrial applications, yet controversy remains regarding underlying elimination mechanisms kinetics....

Abstract This study investigated the performance of continuous-flow electrocoagulation (CFR-EC) reactor for aged landfill leachate treatment with a novel configuration iron and aluminum electrodes to enhance applicability process. The effects applied current density (ACD), initial pH, hydraulic retention time (HRT) on percentage removal COD, TOC, BOD 5 , color, turbidity, heavy metals (HM s ) w...

The present study focused on the treatment of hospital wastewater generated from Al-Diwaniya located at city/ southern Iraq via an Electrocoagulation (EC) process with SS/Fe electrodes. Response Surface Methodology (RSM)  was used to evaluate main effects parameters, their simultaneous interactions and quadratic effect achieve optimum condition for EC process. Chemical Oxygen Demand (COD) ...

Urban and industrial effluents, stormwater, road runoff, agricultural urban or mine waste deposits fuel storage sites can lead to the contamination of water sources with compounds that are hard biodegrade, such as heavy metals, whose removal requires advanced expensive technologies. The Sustainable Development Goals (SDGs) established by UN current requirements in terms energy efficiency, reduc...

In this study, three different electrocoagulation (EC) sludges were studied as an adsorbent (removal of humic acids) and a catalyst [catalytic wet peroxide oxidation (CWPO) bisphenol A (BPA)]. The originated from process in which aluminum (Al) iron (Fe) electrodes used for the treatment mining industry wastewater. All materials dried sludge calcined material. stability these was neutral alkalin...

In this study, a self-designed simultaneous crossflow electrocoagulation/electrofiltration (EC/EF) treatment module was evaluated for its overall reatment performance by treating chemical mechanical polishing (CMP) wastewaters including Cu-CMP wastewater and oxide-CMP wastewater. he critical electric field strengths for Cu-CMP and oxide-CMP wastewaters were determined to be 35 and 30 V/cm, resp...

This paper reviews the development, design and applications of electrochemical technologies in water and wastewater treatment. Particular focus was given to electrodeposition, electrocoagulation (EC), electroflotation (EF) and electrooxidation. Over 300 related publications were reviewed with 221 cited or analyzed. Electrodeposition is effective in recover heavy metals from wastewater streams. ...
