Abstract :
As a new type of potentially menacing micropollutant, microplastics (MPs) are extensively released in water, and humans may be exposed to them through drinking water. The effectiveness of conventional drinking water treatment plants (DWTPs) for the elimiation of MPs differs in terms of the plant size and shape. This paper aims to study the treatment efficiency of DWTPs for MPs removal. This work summarizes the MP components (types, sizes, forms, and abundance) in potable water sources, and critically reviews the elimination performance and impacts of MPs in different potable water treatment systems. In order to detect MPs in drinking water, Fourier Transform Infrared Spectrometry (FTIR) (25%), Raman Spectroscopy (15%), and other methods (40%) were used. The highest removal efficiency of DWTPs (99.99%) was achieved in England and Wales and the lowest removal efficiency (49.69%) in China (Tianjin). In this study MPs in the inlet (surface and ground waters) DWTPs vary significantly, ranging from zero to 6614 MP particles/L. MPs were observed at minimum size of 163 nm and maximum size of 5 mm. Finally, further research needs to be carried to explore the release of MPs from DWTPs.
