Effect of hydrocyclone design in microplastics-water separation by using computational fluid dynamics simulations

Researchers used computer fluid dynamics simulations to test and optimize the design of hydrocyclones — spinning funnel-shaped devices that use centrifugal force to separate particles from water — for removing microplastics, finding an optimized geometry that achieved 76% microplastic recovery. The results show that carefully tuning the proportions of a hydrocyclone's components can significantly improve its ability to filter microplastics from water at scale.

Effect of hydrocyclone size on microplastics separation: a computational fluid dynamics investigation

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.

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.

Migration and Removal of Microplastics in a Dual-Cone Mini-Hydrocyclone

Researchers analysed microplastic migration and separation in a dual-cone mini-hydrocyclone using a numerically verified model, examining how feed flow rate, MP volume fraction, and particle density affect separation efficiency.

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.
