In recent years, the awareness of microplastic pollution has been rising gradually. Unpredicted phenomenon, facts and reports on perniciousness prompt more researches of removal microplastics from water circulation. Since the doubtful feasibility of direct removal in ocean and finding a perfect alternative for plastic, and obvious human impact on microplastic distribution, wastewater treatment represents a more practical solution. This report will mainly focus on electrocoagulation, which is one of the technologies used to remove microplastics in effluent treatment. There are three main stages of the mechanism: dissolution, coagulation and flocculation, and during this process many factors including electric current, temperature, initial pH and electrode material would influence the removal efficiency. Electrocoagulation exceeds other technologies in environmental compatibility, operational cost and good application etc., while drawbacks such as high electric consumption, unstable yield and sacrificial electrode affects the applied range, where future researches can make efforts on by optimizing on the existing foundation and fostering new technical combination.
