ClearJet Drop Enrichment: A Low-Cost Method for Simultaneous PFAS and Microplastics Removal from Drinking Water
Researchers developed a low-cost water treatment method that uses the tiny droplets formed when bubbles burst at a water surface to simultaneously remove both PFAS ('forever chemicals') and fine microplastics from drinking water, achieving up to 99% removal of long-chain PFAS and microplastics. Adding a low-cost ion-exchange resin extended the approach to short-chain PFAS as well. This is significant because conventional water treatment struggles with both contaminants, and this bubble-based method offers a simple, scalable solution with minimal materials.

This study evaluated froth flotation as a method for removing microplastics from water, finding that surface hydrophobicity governs flotation efficiency and that the technique shows promise as a scalable treatment option for certain polymer types.
Enhanced removal of microplastics using microflotation
Researchers demonstrated that microflotation, a process using optimized small bubble sizes, can remove 84-98% of microplastics from water without requiring chemical additives like flocculants or coagulants. Using a pilot-scale system, they tested removal of 30 and 100 micrometer polystyrene particles across environmentally relevant concentrations. The study suggests that microflotation offers an efficient and chemical-free alternative for microplastic removal in water treatment applications.

Researchers developed a microbubble flotation system that removes over 98% of microplastics and 95% of detergent surfactants from laundry wastewater. The study successfully scaled the approach from bench-level to a pilot-scale column over 5 meters tall, demonstrating a practical, cost-effective solution for treating one of the largest sources of microplastic pollution entering waterways.
Emerging investigator series: suspended air nanobubbles in water can shuttle polystyrene nanoplastics to the air–water interface
Nanobubbles suspended in water can physically carry nanoplastic particles to the air-water interface and concentrate them there, but only when the repulsive electrical charge between the particles and bubbles is reduced by adjusting pH. This discovery points toward a potential low-energy method for removing nanoplastics from water, which is currently one of the hardest fractions of plastic pollution to filter out.
Effective Removal of Microplastics Using a Process of Ozonation Followed by Flocculation with Aluminum Sulfate and Polyacrylamide
Researchers tested a two-step water treatment process combining ozonation with flocculation to remove microplastics. They found that ozone pretreatment roughened the microplastic surfaces and added chemical groups that dramatically improved removal rates, from 40% to 91%, during the subsequent flocculation step. The findings suggest this combined approach could significantly enhance microplastic removal in conventional water treatment plants.
Simultaneous monitoring of flow patterns, and bubble, and plastics micro-particle characteristics in Dissolved Air Flotation (DAF)

The study offers insights for optimizing DAF water treatment systems to better capture microplastics during drinking water or wastewater processing.
The rise and rupture of bubbles: applications to biofouling, microplastic pollution, and sea spray aerosols

Scientists developed a nanobubble-assisted flotation technique that improves removal of very small microplastics (under 10 micrometers) from wastewater by up to 17% compared to traditional methods. Removing these tiny particles is especially important because their small size makes them more likely to pass through water treatment and eventually be consumed by humans.
Efficient removal of nanoplastics from industrial wastewater through synergetic electrophoretic deposition and particle-stabilized foam formation
Researchers developed a new method to remove nanoplastics from industrial wastewater by combining electrophoretic deposition with particle-stabilized foam formation. The process uses pH changes from water electrolysis to make tiny plastic particles attach to bubbles near the electrode, achieving removal rates above 90%. The technique was successfully tested on real-world wastewater from paint and plastics manufacturing, offering a practical approach to addressing nanoplastic pollution that is too small for conventional filters.
Nanoscale insight into the interaction mechanism underlying the transport of microplastics by bubbles in aqueous environment
Nanoscale experiments revealed that bubble capture of microplastics in water is governed by hydrophobic interactions and surface charge complementarity between bubbles and MP particles.
