Wastewater, treated by elctrocoagulation gives palatable,clear,colorless,and odorless. Sludge formed by elctrocoagulation tends to be readily settleable and easy to dewater,because it is composed mainly of metallic oxides/hydroxides.Above all it is a low sludge producing techniques. Flocs formed by this process are similar to the chemical flocs,except that these flocs tends to be much larger ...
