Jet Drop Enrichment: A Low-Cost Method for Simultaneous PFAS and Microplastics Removal from Drinking Water
AI summary Read the abstract
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.
Per- and polyfluoroalkyl substances (PFAS) and fine microplastics (MPs, 1–10 μm) are emerging contaminants in drinking water that conventional treatment technologies struggle to remove. Here we developed a sustainable and low-cost approach that harnesses jet drops generated by bursting bubbles to collect pollutants, achieving simultaneous removal of PFAS and MPs. Our results show that both long-chain PFAS (PFOS, PFNA, PFDA, PFOA, PFHxS) and fine MPs become highly enriched at the air–water interface and are efficiently transferred into jet drops, yielding removal efficiencies up to 99% for long-chain PFAS and MPs. In contrast, short-chain PFAS exhibit lower removal because of their weaker surface activity. To address this limitation, we coupled an anion-exchange resin (AER) pretreatment with jet drop enrichment (JDE). The combined JDE+AER system raises short-chain PFAS removal to over 90% while cutting material use and costs. This work illuminates interfacial removal mechanisms and offers a scalable, economical, and environmentally benign option for advanced drinking water treatment.

Jet Drop Enrichment: A Low-Cost Method for Simultaneous PFAS and Microplastics Removal from Drinking Water
AI summary Read the abstract
Per- and polyfluoroalkyl substances (PFAS) and tiny microplastics are two of the hardest contaminants to remove from drinking water, and this study proposes a surprising solution: harnessing the micro-bubbles that naturally burst at a water surface, which fling surface-active pollutants into tiny airborne droplets that can be collected. The method achieved up to 99% removal of long-chain PFAS and fine microplastics simultaneously, and when combined with a resin pre-treatment step, also captured shorter-chain PFAS at over 90% efficiency. This bubble-based approach is low-energy, low-cost, and could complement existing water treatment infrastructure.

The Combination of Micro-Nano Bubbles and Other Technologies for Emerging Contaminants' Elimination in Water Treatment
AI summary Read the abstract
Everyday water treatment struggles to remove newer pollutants like drug residues, "forever chemicals" (PFAS), microplastics, and modern pesticides—substances that can build up in our bodies and environment over time. This review rounds up research on a promising fix: tiny gas bubbles (called micro-nano bubbles) that, when paired with other treatments like ozone or specialized filters, may more effectively break down these contaminants in water. While the technology shows real promise, this paper is a summary of existing studies rather than new experiments, and researchers still need to work out the best ways to apply it in real-world water systems.
Nanobubble-Assisted Coagulation–Flocculation–Flotation: Mechanistic Insights into PVC Micro/Nanoplastic Separation
AI summary Read the abstract
Scientists found a way to remove tiny PVC plastic particles (a common type of microplastic) from water more effectively by combining tiny air bubbles with water treatment chemicals. The best combination removed up to 90% of these particles, which matters because microplastics in drinking water are a growing health concern. This early stage research could lead to better water treatment methods in the future.
