“…This was confirmed by Ben-David et al, (2021) as in winter they noticed a doubling of MPs compared with the other seasons. Conversely, in Thailand, Kittipongvises et al, (2022) detected higher MPs abundance in the WWTPs during the dry season in two years, assuming that the mobility and dilution of the MPs, road run-off or other transport-related emission sources plus combined sewerage systems, were the determining factors on their findings.…”

A Review of the Origins of Microplastics arriving at Wastewater Treatment Plants

Concerns regarding the impacts of microplastics in the global environment have brought into focus the need to understand better their origins, transport, and fate. Wastewaters (WW) are important in this regard: discharges from households, commercial and industrial premises, and surface run-off deliver microplastics to wastewater treatment plants (WWTPs) via sewerage systems, through which they are removed along with sewage sludge or destined for release into the environment in treated effluent. This review provides a contemporary and critical analysis of factors influencing the quantities and composition of microplastics (MPs) reaching wastewater treatment plants, including both primary and secondary sources. Three specific areas of concern were highlighted. First, current legislation, where present, needs to address regulation of microplastics in personal care and cosmetic products that cross international borders. Secondly, accurate estimation of microplastics arising from some sources and activities (e.g., mis-managed waste and hand washing of textiles) is challenging and estimated contributions of associated microplastics remain unsatisfactory as a basis for management decisions. Thirdly, information relating to microplastics in personal care and cosmetic products used by male consumers is lacking and contributions of such products to wastewater remain uncertain. We recommend that (1) voluntary practices and programmes should be replaced with formal regulation to achieve compliance, and (2) the role of consumers’ behaviour in generating microplastics that are destined for wastewater treatment plants remains largely unknown and that more research in this domain is needed.

“…This may be explained by the fact that Icelandic wastewater is known to be very dilute, due to mixing with rainwater and a general high-water consumption by industry in Iceland (more than 2,000 L capita -1 day -1 in 2015 all-inclusive according to Statistics Iceland). Dilution by runoff has by others been shown to impact concentrations of MPs in raw sewage concentration in combined sewer systems (Kittipongvises et al 2022).…”

“…However, the detection and analysis methods for emerging contaminants such as Pharmaceuticals and Personal Care Products (PPCPs), Endocrine Disruptors (EDs), Antibiotics Resistance Genes (ARGs), Persistent Organic Pollutants (POPs), MPs, etc., have only been mentioned in recent years, and our knowledge of the removal efficiency and mechanism of WWTPs for these contaminants is limited [23,24]. The removal of MPs in WWTPs is significantly influenced by various factors, including the types of treatment processes, the contribution of rainwater, the daily treatment capacity, and the operation mode, as indicated by previous studies [25,26]. Currently, a standardized approach for sampling and detection methods of MPs is lacking, while the availability of comprehensive data on the removal efficacy of MPs in operational WWTPs is currently limited.…”

Microplastics have been widely detected in wastewater treatment plants, but there is still a significant dearth of research data on the removal efficiency of microplastics in such plants. The present study focused on three wastewater treatment plants situated in Zhengzhou, China. On-site sampling and Raman spectrum detection techniques were employed to identify microplastics in both wastewater and sludge samples, while the removal efficiency of microplastics was quantified for each plant. Results showed that the abundance of microplastics in influent exhibited ranging from 147.5 ± 2.6 to 288.8 ± 11.8 n/L, while the range in sludge samples was from 12,024.7 ± 1737.0 n/kgdw to 20,818.4 ± 5662.0 n/kgdw. The removal efficiencies of microplastics in the three WWTPs ranged from 76.2% to 91.2%. The primary components of microplastics were generally identified as fibers ranging in size from 10 to 100 μm. The samples collectively exhibited a total of seven distinct colors, with the predominant proportion being transparent. Polypropylene was the polymer type with the highest proportion. The sludge in WWTPs plays a pivotal role in the accumulation of MPs from wastewater bodies, necessitating increased attention toward its proper disposal in future endeavors.
