Process Performance of Electrocoagulation in Treating Sanitary Landfill Leachate as Pretreatment Unit

Since leachate treatment requires multiple stages of treatment, electrocoagulation (EC) is proposed as a pretreatment unit to compliment the main unit operations treatment such as membrane or biological treatment. EC was proposed in this study to overcome some of the problems with conventional treat...
