During the last two decades, and particularly during the last few years, the environmental sector has shown a largely growing interest in the treatment of different types of water and wastewater by electrocoagulation (EC). The aim of this work was to review studies, conducted mainly during 2008-2011, on the wide and versatile range of feasible EC applications employed in the purification of dif...

Abstract The consecutive removal of fluoride (defluoridation) and pathogens (disinfection) in drinking water through combined electrocoagulation-inline-electrolytic disinfection (EC–ECl2) process with aluminum dimension-stable mixed oxide electrodes was reported this study. Laboratory trials were conducted on the effects flow rate, initial pH, current density, supporting electrolytes for defluo...

In this study, the investigation of 4-clorophenol (CP) removal from aqueous solutions using copper electrodes by electrocoagulation (EC) process was done. The effects various experimental parameters such as pH, current density and exposure time, which affect EC process, on 4-CP were investigated. To optimize response surface methodology (RSM) Box Behnken Design used MINITAB program, a series se...

The efficacy of a laboratory electrocoagulation (EC) system for treating egg processing plant waste-water (WW) is reported. For simulated and industrial egg processing WW, chemical oxygen demand, turbidity, and total suspended solids (TSS) were reduced 92 to 97%, 97%, and 99%, respectively, after treatment with EC. The final TSS concentration and turbidity values were 30 mg/L and 5 formazin tur...

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...

Organic matter is a widely occurring pollutant in freshwater sources due to the extensive use of synthetic organic compounds industry and natural occurrence Earth’s crust. causes adverse effects on performance water treatment plants, such as accelerated bacterial growth increased consumption chemical coagulants. also has ability chelate some heavy metals forming refractory complexes that resist...

Background & Aims of the Study: Spent filter backwash water (SFBW) consists of 1-5% of the total treated water typically and it has a high turbidity. Because of the scarcity of water resources and in order to prevent the environmental contamination, effluent treatment of rapid sand filter backwashing is unavoidable. One of the new technologies for removal of turbidity from the ...

OBJECTIVE To evaluate the size of ovarian damage caused by ovarian drilling in polycystic ovary syndrome, the amount of inflicted damage was assessed for the most frequently used ovarian drilling techniques. DESIGN Experimental prospective design. SETTING University clinic. PATIENT(S) Six fresh bovine ovaries per technique. INTERVENTION(S) Carbon dioxide (CO(2)) laser, monopolar electro...

The electrocoagulation (EC) process introduces coagulants by electrochemical means, and is widely adopted for removing heavy metals, besides other contaminants, such as organic pollutants, suspended dissolved solids, colloidal materials, etc. However, its capability can vary significantly, depending on the operating conditions. Although most of investigations so far are limited at laboratory le...

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...
