In practice, direct current (DC) is used in an electrocoagulation processes. In this case, an impermeable oxide layer may form on the cathode as well as corrosion formation on the anode due to oxidation. This prevents the effective current transfer between the anode and cathode, so the efficiency of electrocoagulation processes declines. These disadvantages of DC have been diminished by adoptin...

Electrocoagulation (EC) was used for the removal of anthraquinone dye, Alizarin Red S (ARS) from aqueous solution. The process was carried out in a batch electrochemical cell with Al electrodes in a monopolar connection. The effects of some important parameters such as current density, pH, temperature and initial dye concentration, on the process were investigated. Equilibrium was attained afte...

background existence of fluoride in drinking water above the permissible level causes human skeletal fluorosis. objectives electrocoagulation by iron and aluminum electrodes was proposed for removing fluoride from drinking water. materials and methods effects of different operating conditions such as treatment time, initial ph, applied voltage, type and number of electrodes, the spaces between ...

Background: Natural organic matter is the cause of many problems associated with water treatment such as the presence of disinfection by-products (DBPs) and membrane fouling during water filtration. In this study, the performance of the peroxi-electrocoagulation process (PEP) was investigated for the removal of humic acids (HAs) from aqueous solutions. Methods: PEP was carried out for the remov...

The reuse of treated domestic wastewater is an imperative source water for numerous purposes. treatment municipal can be process by utilizing the technique electrocoagulation. Electrocoagulation (EC) eco-friendly that combines functions and advantages conventional coagulation, flotation, electrochemistry in treatment. aim present study was to assess potential electrocoagulation removing COD, BO...

this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion were...

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 ...
