Removal of microplastics from wastewater for world water pool protection
AI summary Read the abstract
This review examines existing techniques for removing microplastics from treated wastewater before it is released into natural water bodies, noting that standard treatment plants only remove 83–98% of microplastics — still leaving billions of particles entering ecosystems daily. Advanced options like membrane bioreactors and biosorbents made from agricultural waste show promise but remain costly to scale.
Microplastics Wastewater Cleaning BiosorbentsMicroplastics are one of the new pollutants and are a threat to natural aquatic ecosystems as well as human health.After entering natural reservoirs, microplastic particles are quickly settled and covered with surfactants of microbial origin.This fundamentally changes the properties and behavior of MP in water: particles become highly hydrophilic and acquire the ability to absorb many pollutants, such as metal ions and pharmaceuticals.This changes the properties and behavior of microplastics in water: particles become highly hydrophilic and acquire the ability to absorb many pollutants, such as metal ions and pharmaceuticals.Particles of microplastics are not removed during the treatment of wastewater at municipal treatment plants and in large quantities enter with purified waters in natural reservoirs.Therefore, it is necessary to develop additional measures for microplastic removal from purified wastewater after their treatment at municipal treatment plants.The present review considers techniques aimed to remove microplastics from purified wastewater to protect the environment.It has been found that when treating wastewater using traditional technology, it is possible to remove from 83% to 98% of microplastics from its initial amount.However, given the huge volumes of treated wastewater entering natural reservoir, this causes a real threat to the environment.To further remove microplastics, it is possible to use flocculation or filtration as a modification of existing water treatment systems, as well as tertiary treatment methods, such as purification in a membrane bioreactor, reverse osmosis or ultrafiltration units.All of these technologies can significantly increase the percentage of removed microplastic, but are expensive, making them difficult to use at a large scale.A promising approach is the use of biosorbents (biomass of agricultural or forest waste).

Removal of microplastics from wastewater: available techniques and way forward
AI summary Read the abstract
This review surveys the available techniques for removing microplastics from wastewater, including filtration, coagulation, biological treatment, and advanced methods like membrane bioreactors. Researchers found that while conventional treatment plants can remove a substantial fraction of microplastics, significant amounts still pass through to the environment. The study emphasizes the need for upgrading wastewater treatment systems to better capture these emerging contaminants.
A comprehensive review on advanced wastewater treatment technologies for microplastic control
AI summary Read the abstract
Tiny plastic particles called microplastics are ending up in our water supply, and this review paper looked at how well wastewater treatment plants remove them before water gets released back into the environment. The findings show that while current treatment methods (like filtering, chemical processes, and even plastic-eating bacteria) can remove a good chunk of microplastics, none work perfectly, and some can be costly, energy-intensive, or even break plastics into smaller pieces that are harder to catch. This matters because microplastics that slip through treatment can end up in rivers, soil, and eventually our food and drinking water, so better, cheaper removal technology is
Conventional and Advanced Treatment Technologies for Microplastics in Water Treatment Facilities
AI summary Read the abstract
This review evaluated both conventional and advanced water treatment methods for removing microplastics from wastewater. Researchers found that while techniques like coagulation, filtration, and membrane bioreactors can remove most microplastics, treatment plants still release significant quantities due to the sheer volume of water processed, and microplastic-laden sludge applied to farmland creates another pathway for environmental contamination.
Removal of microplastic particles during municipal wastewater treatment: A current review
AI summary Read the abstract
This review examines how effectively municipal wastewater treatment plants remove microplastics before discharging water into the environment. Researchers found that while advanced treatment can remove over 98% of microplastics, large facilities may still release billions of particles daily, especially nanoplastics smaller than 1 micrometer that are harder to capture. The study suggests that additional purification steps and improved existing processes are needed to better protect waterways from microplastic contamination.
Microplastic removal and management strategies for wastewater treatment plants
AI summary Read the abstract
This review examines how well different wastewater treatment technologies remove microplastics and what management strategies can improve performance. While conventional treatment plants can remove a large percentage of microplastics from water, the particles often end up concentrated in sewage sludge that gets applied to farmland. The study highlights the need for advanced treatment options and better management of biosolids to prevent microplastics from simply being transferred from water to soil.
