The Standard and Reverse Mode Operation of a Hydrocyclone for Microplastic Separation
Researchers tested whether hydrocyclones — low-cost centrifugal separation devices — could efficiently separate microplastics from water, finding that particles denser than water were captured in standard mode while lighter particles required reverse mode operation. The system effectively separated all four test microplastic types based on density, suggesting hydrocyclones are a scalable, low-energy option for removing microplastics from industrial and municipal water streams.

The study demonstrates that mini-hydrocyclones could serve as a compact and energy-efficient technology for removing very small microplastics from water treatment systems.
High-efficiency microplastic removal in water treatment based on short flow control of hydrocyclone: Mechanism and performance
Researchers developed an improved mini-hydrocyclone device that removes over 98% of microplastics from water, a 34% improvement over conventional designs. The device uses tiny overflow channels to prevent small plastic particles from escaping during the separation process. This technology could be scaled up for industrial water treatment, helping to remove microplastics before treated water reaches the environment or drinking water supplies.

Researchers used computer fluid dynamics simulations to test how the size of a hydrocyclone — a cone-shaped device that uses spinning water to separate particles — affects its ability to remove microplastics from water. Smaller hydrocyclones generated stronger centrifugal forces and recovered more microplastics, though they also required more energy, revealing a trade-off that engineers must balance in real-world water treatment systems.

This is dramatically faster than current lab methods and could help scientists study microplastic pollution at much larger scales without needing toxic chemicals.
