“…The size of MP in the raw water were found to be the major factor influencing fouling during freshwater ultrafiltration treatment with the most severe effects at a MP size of 1 μm. 212 However, continuous filter module rotation could significantly reduce the fouling and the treatment became more attractive for large scale application. MP in landfill leachate were successfully removed using membrane separation.…”

“…Following coagulation, there was a low removal efficiency (below 15%) of PE particles, indicating that the only coagulation process is insufficient to remove MPs. However, when coagulation was enhanced with polyacrylamide (PAM), PE removal efficiency was significantly increased from 13 to 91% for small-particle size ( d < 0.5 mm) (Li et al 2021 ).…”

Microplastics (MPs) and SARS-CoV-2 interact due to their widespread presence in our environment and affect the virus' behaviour indoors and outdoors. Therefore, it is necessary to study the interaction between MPs and SARS-CoV-2. The environmental damage caused by MPs is increasing globally. Emerging pollutants may adversely affect organisms, especially sewage, posing a threat to human health, animal health, and the ecological system. A significant concern with MPs in the air is that they are a vital component of MPs in the other environmental compartments, such as water and soil, which may affect human health through ingesting or inhaling. This work introduces the fundamental knowledge of various methods in advanced water treatment, including membrane bioreactors, advanced oxidation processes, adsorption, etc., are highly effective in removing MPs; they can still serve as an entrance route due to their constantly being discharged into aquatic environments. Following that, an analysis of each process for MPs' removal and mitigation or prevention of SARS-CoV-2 contamination is discussed. Next, an airborne microplastic has been reported in urban areas, raising health concerns since aerosols are considered a possible route of SARS-CoV-2 disease transmission and bind to airborne MP surfaces. The MPs can be removed from wastewater through conventional treatment processes with physical processes such as screening, grit chambers, and pre-sedimentation.

“…Membrane technology has been widely used in DWT, which usually comes after the CF or CFS treatment. So far, less than 10 studies have explored the removal and impacts of MPs in membrane processes in laboratory-scale DWT (Ma et al, 2019a;Ma et al, 2019b;Li et al, 2020;Li et al, 2021). Ultrafiltration (UF), microfiltration (MF), or reverse osmosis (RO) membranes have been studied in these studies.…”

“…Previous research indicated that MPs could influence membrane fouling. Without CFS pretreatment, the MPs can increase membrane fouling with the smaller MPs or higher MP concentrations generally leading to severer membrane fouling (Ma et al, 2019a;Ma et al, 2019b;Li et al, 2021). On the other hand, when CFS pretreatment was in place, Ma et al (2019a) and Ma et al (2019b) found that the PE MPs alleviated the fouling caused by the coagulant flocs, with the larger MPs being more beneficial.…”

“…On the other hand, when CFS pretreatment was in place, Ma et al (2019a) and Ma et al (2019b) found that the PE MPs alleviated the fouling caused by the coagulant flocs, with the larger MPs being more beneficial. As for the effect on membrane fouling of different MP sizes, Li et al (2021) documented that the 1-μm MPs led to the worst membrane fouling among the 0.1-, 1-, 10-, and 18-μm MPs, suggesting a critical MP size of 1 μm for their membrane filtration. Moreover, MPs can enhance organic fouling and worsen the irreversibility of fouling according to Li et al (2020).…”

Microplastics (MPs) have been widely detected in drinking water sources and tap water, raising the concern of the effectiveness of drinking water treatment plants (DWTPs) in protecting the public from exposure to MPs through drinking water. We collected and analyzed the available research articles up to August 2021 on MPs in drinking water treatment (DWT), including laboratory- and full-scale studies. This article summarizes the major MP compositions (materials, sizes, shapes, and concentrations) in drinking water sources, and critically reviews the removal efficiency and impacts of MPs in various drinking water treatment processes. The discussed drinking water treatment processes include coagulation-flocculation (CF), membrane filtration, sand filtration, and granular activated carbon (GAC) filtration. 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, the article framed the major challenges and future research directions on MPs and nanoplastics (NPs) in DWT.
