ClearEffects of Microplastics on Pre-treatment Process for Seawater Desalination
Researchers examined the effects of microplastics on pre-treatment processes used in seawater desalination, investigating how microplastic contamination interferes with filtration and other preparatory steps essential to producing potable water from seawater.
Characteristics, Environmental Impact, and Treatment of Reverse Osmosis Concentrate Generated from Municipal and Industrial Wastewater: A Review and Futuristic Outlook
Despite its title referencing reverse osmosis concentrate, this paper reviews management challenges for the concentrated wastewater byproduct produced by reverse osmosis treatment systems — not microplastic pollution specifically. It surveys technologies for minimizing this waste stream under a "zero liquid discharge" framework and does not study microplastics or their health effects.
Impact of nanoplastics on membrane scaling and fouling in reverse osmosis desalination process
This study investigated how polystyrene nanoplastics affect membrane scaling and fouling in reverse osmosis desalination, finding that nanoplastics interacted with silica to alter fouling behavior and reduce membrane performance. The results highlight nanoplastics as a potentially disruptive contaminant for desalination infrastructure.
Microplastic in desalinated and seawater: Comparative assessment
Researchers compared microplastic concentrations in desalinated and raw seawater in the Canary Islands, evaluating how well the desalination process reduces plastic particle contamination. Desalination removed a substantial fraction of microplastics but did not eliminate them entirely from drinking water.
Microplastic in desalinated and seawater: Comparative assessment
Researchers compared microplastic concentrations in desalinated water and seawater in the Canary Islands, where desalination supplies a significant portion of the drinking water. Microplastics were detected in both source seawater and desalinated water, with desalination providing partial but incomplete removal.
An Assessment of Renewable Energies in a Seawater Desalination Plant with Reverse Osmosis Membranes
This engineering study evaluated whether integrating solar and wind energy into a seawater desalination plant could reduce its carbon footprint. Combining renewable energy with newer low-energy reverse osmosis membranes significantly reduced emissions compared to conventional fossil-fuel-powered desalination. This paper is focused on energy technology and is not directly related to microplastics.
Behavior and removal of microplastics during desalination in a lab-scale direct contact membrane distillation system
Researchers explored microplastic behavior in a direct contact membrane distillation system for seawater desalination, finding that the membrane effectively removed microplastics from drinking water while certain plastic types degraded under the high operating temperatures.
Effect of polypropylene microplastics on the performance of membrane bioreactors in wastewater treatment
Researchers studied how polypropylene microplastics affect membrane bioreactors, a type of wastewater treatment system. They found that while these systems can effectively filter out microplastics, higher concentrations and smaller particle sizes caused membrane clogging and reduced treatment efficiency over time, which is important for designing better wastewater treatment facilities.
The potential for a plastic recycling facility to release microplastic pollution and possible filtration remediation effectiveness
Researchers conducted a pilot study at a mixed plastics recycling facility in the UK and found that raw wash water contained extremely high concentrations of microplastic particles. They tested filtration systems and found that while most particles larger than 5 micrometers were successfully removed, smaller particles still passed through. The study highlights that recycling facilities themselves can be significant point sources of microplastic pollution to waterways if proper filtration is not in place.
Microplastic characterization and assessment of removal efficiency in an urban and industrial wastewater treatment plant with submarine emission discharge
Researchers evaluated how effectively a wastewater treatment plant in Morocco removes microplastics from combined urban and industrial wastewater. They found that while the plant's lamellar settling system removed a significant portion of microplastics, treated water discharged through the submarine outfall still contained measurable levels. The study underscores that current wastewater treatment technologies may not fully prevent microplastic pollution from reaching marine environments.
Microplastics in small semi-industrial desalination stations and bottled waters: Human exposure and emerging health concerns
Researchers analyzed microplastic contamination in bottled water and small semi-industrial desalination stations in a water-scarce region. The study found microplastics present in both water sources, with higher levels than expected in desalination station output, raising concerns about human exposure through drinking water and highlighting the need for improved filtration standards.

Analysis of membrane surface after the filtration of surface water containing microplastic
Researchers tested ultrafiltration and nanofiltration membranes on real river water containing microplastics and found both membrane types completely removed plastic particles from the filtered water, though the deposited microplastics reduced water flow through the membranes over time — confirming membrane filtration as an effective but imperfect water treatment strategy.
Recent advances on micro/nanoplastic pollution and membrane fouling during water treatment: A review
Researchers reviewed recent advances in understanding how micro- and nanoplastics contribute to membrane fouling during water treatment processes. The study found that while membrane separation effectively removes microplastics from wastewater effluent, fouling caused by plastic particles along with dissolved organics and extracellular polymers remains a key obstacle, and understanding the fouling mechanisms is critical for improving treatment efficiency.

Release of microplastics from polymeric ultrafiltration membrane system for drinking water treatment under different operating conditions
Researchers discovered that the plastic membrane filters used to purify drinking water can actually release microplastics into the treated water. The particles came not just from the membrane itself but also from plastic equipment in the system, meaning that water treatment technology designed to remove contaminants may inadvertently be adding new plastic particles to our drinking water.
Effects of microplastics accumulation on performance of membrane bioreactor for wastewater treatment
Researchers simulated the long-term accumulation of polypropylene microplastics in membrane bioreactors used for wastewater treatment.

The study suggests that microplastic buildup in wastewater treatment systems may affect operational efficiency over time.
Do membrane filtration systems in drinking water treatment plants release nano/microplastics?
