A review of microplastic removal from water and wastewater by membrane technologies

Water Science & Technology, Journal Year: 2023, Volume and Issue: 88(1), P. 199 - 219

Published: June 14, 2023

Microplastics (MPs) cannot be completely removed from water/wastewater in conventional wastewater treatment plants (WWTPs) and drinking water (DWTPs). According to the literature analysis, membrane technologies, one of advanced are most effective promising technologies for MP removal wastewater. In this paper, firstly, properties MPs commonly present WWTPs/DWTPs efficiency briefly reviewed. addition, research studies on by microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), bioreactors (MBRs) next section, filtration is compared with other methods used water/wastewater, advantages/disadvantages discussed. Moreover, problem fouling during potential release polymeric structure Finally, based literature, current status deficiencies identified, recommendations made further studies.

Nano- and microplastics commonly cause adverse impacts on plants at environmentally relevant levels: A systematic review

Over the last years there has been significant research on presence and effects of plastics in terrestrial systems. Here we summarize current findings nano- microplastics (NMPs) plants, with aim to determine patterns response sensitive endpoints. We conducted a systematic review (based 78 studies) NMPs germination, plant growth biochemical biomarkers. This highlights that majority studies date have used pristine polystyrene or polyethylene particles, either hydroponic pot-plant setup. Based these found plants are widespread. noted similar responses between within monocots dicots NMPs, except for consistent lower germination seen exposed NMPs. During early development, root more strongly affected compared shoot growth. induced adverse biomass length most tested species (lettuce, wheat, corn, rice) irrespective polymer type size used. Moreover, biomarker were across species; chlorophyll levels commonly negatively affected, while stress indicators (e.g., ROS free radicals) respondents antioxidant enzymes) consistently upregulated. In addition, observed at environmentally relevant levels. These provide clear evidence wide-ranging impacts performance. However, as under highly controlled conditions plastics, is an urgent need test realistic ensure lab-based can be extrapolated field.

Nano and microplastics occurrence in wastewater treatment plants: A comprehensive understanding of microplastics fragmentation and their removal

Chemosphere, Journal Year: 2023, Volume and Issue: 334, P. 139011 - 139011

Nano/microplastic (NP/MP) pollution is a growing concern for the water environment. Wastewater treatment plants (WWTPs) are considered major recipients of MP before discharging into local waterbodies. MPs enter WWTPs mainly from synthetic fibers through washing activities and personal care products. To control prevent NP/MP pollution, it essential to have comprehensive understanding their characteristics, fragmentation mechanisms, effectiveness current processes used in removal. Therefore, objectives this study (i) understand detailed mapping WWTP, (ii) mechanisms NP, (iii) investigate removal efficiency by existing WWTP. This found that fiber dominant shape MP, polyethylene, polypropylene, polyethylene terephthalate, polystyrene polymer type wastewater samples. Crack propagation mechanical breakdown due shear forces induced facilities (e.g., pumping, mixing, bubbling) could be causes NP generation Conventional ineffective complete MPs. Although these capable removing ∼95% MPs, they tend accumulate sludge. Thus, significant number may still released environment on daily basis. suggested using DAF process primary unit can an effective strategy initial stage goes secondary tertiary stage.
