The occurrence of microplastics (MPs) in urban water has aroused wide concern because of their persistence and potential adverse impacts on human health and wildlife. More importantly, this adverse effect will be continuously transmitted and accumulated through the aquatic food chain of urban water. Therefore, there is an urgent need to develop methods that can effectively remove or degrade MPs. This chapter systematically summarizes the widely studied methods for the separation, removal, and degradation of MPs, including coagulation, flocculation, and sedimentation (CFS), electrocoagulation, filtration, membrane separation, adsorption, photocatalysis, and chemical oxidation methods, respectively. The corresponding mechanisms for removing and degrading MPs are also discussed. In addition, a prospect for enhanced MPs pollution control and their removal and degradation in urban water are proposed. This chapter offers detailed information on current methods of removing and degrading MPs and constructive suggestions for future control of MPs pollution from urban water.
