Abstract

Plastics and related products have made our life easier due to their extensive application in household chores and industry. Plastic bags and bottled water are of two common usages of plastics that could be observed almost anywhere around the world. Large production of plastics has made them a serious concern for the environment. Over years, plastics are disintegrated via nature (such as wind or sun) or anthropogenic activities and turn into microplastics having size lower than 5 mm. Unfortunately, detection of microplastics in different media including drinking water, lakes, rivers, soils, sediments, and even tissues of marine life have been reported. In the present chapter general overview of microplastics is presented, then performance of various wastewater treatment plants in different regions is discussed. It was found that current wastewater treatment plants are available for removing microplastics in units such as screening and primary sedimentation; however, in the effluent microplastics still exist and freely release into ecosystem. Considering the large volume of wastewaters, it can be said that large number of microplastics may exist from wastewater treatment plants and enter rivers and lakes that may finally reach our tap water. To prevent risks associated with microplastics in both human and the environment and its spread in the environment, it is fair to employ advanced wastewater treatment methods being capable of removing the residues of microplastics in the effluent.
