Let Us Talk About Microplastic Pollution in Drinking Water Treatment
Microplastic particles (MPs) have become interesting to the water research community and general public due to their global ubiquity and potential impacts on the environment and public health. MPs are plastic beads, fibers, and fragments in the micrometer size range (< 5 mm), which can be ingested by aquatic fauna across a range of feeding guilds. MPs result from a wide variety of sources, including fragmentation of larger plastics and laundering of synthetic fabrics. Previous studies on animals have indicated that ingestion of MPs could lead to serious health issues, including liver stress response and tumor formation. Through literature analyses and laboratory experiments, we explored microplastic removal in various conventional and advanced water treatment processes, such as coagulation, granular media filtration, and membrane filtration. This presentation speaks to the major MP compositions (materials, sizes, shapes, and concentrations) in drinking water sources and the removal efficiency of MPs in these different drinking water treatment (DWT) processes. Current DWT processes that are purposed for particle removal are generally effective in reducing MPs in water. Various influential factors to MP removal are discussed, such as coagulant type and dose, MP material, shape and size, and water quality. It is anticipated that better MP removal can be achieved by optimizing the treatment conditions. Moreover, this talk will frame the major challenges and future research directions on MPs and nanoplastics (NPs) in DWT.
