ClearOptimising miniaturised hydrocyclones for enhanced separation of microplastics
Researchers optimized the design of miniaturized hydrocyclones for separating small microplastics in the 5-20 micrometer range from water.

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.
