Membrane filtration fouling has become a significant issue that restricts its wide application. The electrocoagulation (EC) technique combines variety of synergistic pollutant removal technologies (including flocculation, redox, and air flotation), which can be an ideal pretreatment process for membrane filtration. In this work, novel Cu2+-doped polypyrrole-coated stainless steel mesh (Cu/PPy–S...

Methods: This study experimentally run consisting a 1.5 L glass beaker and four which installed parallel. each test, 1 wastewater add into reactor, then effect parameters including current density (100-400 A/m2), reaction tim...

In the present study different combinations of Al and Fe electrodes are used for improving treatment efficiency in electrocoagulation (EC) process to purify domestic wastewater. Various factors be studied assessment COD removal form pH (3–9), time (10–60 min), density current (9.0–40 A/m2). Depending on influencing factor Al–Al Fe–Fe able minimize percentage up 85.0 % 90% respectively...

Over the past decade the concern about toxic metals in freshwater has increased. Environmental laws such as the Clean Water Act have forced industries that produce metal containing wastewater to treat their wastewater prior to discharge. The purpose of this study was to investigate the use of a novel method for the minimization of heavy metals in the wastewater from the mining industry. A very ...

The electrocoagulation (EC) method, which is in situ generation of coagulating ions by applying direct electrical current to metallic electrodes, has recently been applied to remove a wide spectrum of pollutants from waters and wastewaters. However, its efficiency is highly influenced by key operational parameters such as electrolysis time and current density. Therefore, the current investigati...

Long-term consumption of water containing excessive fluoride can lead to fluorosis of the teeth and bones. Electrocoagulation (EC) is an electrochemical technique, in which a variety of unwanted dissolved particles and suspended matter can be effectively removed from an aqueous solution by electrolysis. Continuous flow experiments with monopolar aluminium electrodes for fluoride removal were un...

The effectiveness of a hybrid approach comprising electrocoagulation (EC) and adsorption (AD) (using natural zeolite and/or palygorskite) processes to treat raw sanitary landfill leachate (SLL) was investigated in terms color, dissolved chemical oxygen demand (d-COD), nitrate nitrogen (NO3−-N) ammonium (NH4+-N) removal. Optimal EC conditions were found with current density 30 mA cm−2, Fe electr...

The interpretation of processes yielding aqueous contaminant removal in the presence of elemental iron (e.g. in Fe(0)/H(2)O systems) is subject to numerous complications. Reductive transformations by Fe(0) and its primary corrosion products (Fe(II) and H/H(2)) as well as adsorption onto and co-precipitation with secondary and tertiary iron corrosion products (iron hydroxides, oxyhydroxides, and...

In this study electrocoagulation (EC) process with sacrificial aluminum anode was used to separate crude oil from synthetic oily wastewater emulsion. A preliminary experimental study was performed to evaluate the most accurate operating parameters, which are then used for the determination of crude oil removal efficiency. The experimental results indicated that electrocoagulation was very e...

The removal of COD and oil from dairy wastewater was experimentally investigated using direct current (DC) electrocoagulation (EC). In the EC of dairy wastewater, the effects of initial pH, electrolysis time, initial concentration of COD, and current intensity were examined. The COD in the aqueous phase were effectively removed when aluminum plates were used as sacrificial electrodes. The optim...
