Electrocoagulation (EC) and Electrocoagulation/Flotation(ECF) Processes for Removing High Turbidity from Surface Water Using Al and Fe Electrodes

Electrocoagulation (EC) and Electrocoagulation/flotation (ECF) processes are simple and efficient in water and wastewater treatment. In recent years, many investigations have focused on the use of these processes for treating of polluted water. The purpose of this study was to investigate the effici...

In ECF process, 84% in optimum condition. However, in EC  process the maximum removal was found  up to 68% of initial turbidity when using Al-Al and Fe-Fe electrodes in same operation. Based on the result obtained in this study, the type of electrodes in EC and ECF processes  significantly affect the removal rate of high turbid water. Also, it was found that much higher turbidity removal could be achieved by ECF process than that by EC process in the same condition.http://www.wwjournal.ir/article_3093_2378e5d998c977a9c41ec5ca81afbbdd.pdfWater treatmentSeasonal TurbidityElectrocoagulationElectrocoagulation/FlotationAl and Fe Electrodes
