The decolourisation of the reactive Congo red dye from synthetic wastewater was studied using ElectroCoagulation (EC) technique. In an effort to increase removal efficiency, effects operating parameters including flow, inter electrode distance, conductivity, voltage, and Hydraulic Detention Time (HDT) were investigated. An electrochemical cell initially created with aluminum cathode anode. Foll...

Abstract Combining electrocoagulation with another process is a potential strategy for increasing the efficiency of water and wastewater pollutant removal. The integration advanced oxidation processes (AOPs) (EC) demonstrates improved performance. mechanism EC combined ozone (O 3 ), hydrogen peroxide (H 2 O sulfate radicals, electrooxidation (EO), Fenton/electro-Fenton, UV discussed. This revie...

The performance of electrocoagulation (EC) technique for decolorization and chemical oxygen demand (COD) reduction of anaerobically pretreated poultry manure wastewater was investigated in a laboratory batch study. Two identical 15.7-L up-flow anaerobic sludge blanket (UASB) reactors were first run under various organic and hydraulic loading conditions for 216 days. Effects of operating paramet...

This study presents biotreatment of textile wastewaters using electrocoagulation and ozone processes. Ozonation process gave better results than electrocoagulation process. For electrocoagulation, optimum working conditions were found as follows: pH, 6.5; electrode type, iron electrode; current density, 20 mA/cm2; and reaction time, 15 min. Under these circumstances, values determined for elect...

Electrocoagulation (EC) is gaining increased attention for water treatment as it efficiently removes various contaminants. Therefore, EC was applied to remove arsenic from groundwater of a highly contaminated site in Hamburg, Germany. Groundwater containing 3250 and 14,600 µg/L arsenic, mainly Arsenite (As(III)), treated three different batch reactors using monopolar parallel electrode-configur...

Abstract The process of Electrocoagulation (EC), the in-situ production coagulants by passing an electric current through sacrificial electrodes, is free chemical additives and cost-effective. This makes it most widely used water wastewater treatment method. However, literature highlights some significant drawbacks this method including EC unit design limitations. research therefore aimed to de...

the present study investigated oil/water demulsification and treatment of oily wastewater originated from port waste reception facilities by electro coagulation using aluminum electrodes in a batch reactor. the efficiency of al electrodes in removing ss, cod, and oil & grease from wastewater with different current densities and operational times were investigated. the characteristics of th...

Electrocoagulation is an electrochemical method of treating polluted water whereby sacrificial anodes corrode to release active coagulant precursors (usually aluminium or iron cations) into solution. Accompanying electrolytic reactions evolve gas (usually as hydrogen bubbles) at the cathode. Electrocoagulation has a long history as a water treatment technology having been employed to remove a w...

the electrocoagulation (ec) is a simple and efficient method for the treatment of many water and wastewaters.the kinetics of decolorization of acid yellow 23 by ec using iron electrodes was studied. theelectrodecolorization rate follows pseudo-first order kinetic with respect to the ay23 concentration havingkapp= 5.65 cm min-1 at t= 295 k. the rate equation is as follows:ln [ay23]t – ln [ay23]0...
