Abstract

Abstract:

Electro-coagulation process is a kind of physical and chemical reaction process,by which suspended solids,colloids,and other forms of soluble pollutants can effectively be removed,having the advantages,such as high removal efficiency,low influence on environment,low sludge producing rate,simple operation,low dosage of chemicals,etc. The main mechanism of actions of electro-coagulation are introduced. And all kinds of important factors affecting the efficiency of the electrocoagulation reaction process,such as power sources,electrode materials,electrode distance,pH,coexisting ions,etc. are summarized. The present technical limitations and future trends of electro-coagulation are proposed.

Key words: Key words:electro-coagulation, water treatment, coexisting ions
