ClearComparative study of the performance of conventional and modified hydrocyclones in the removal of microplastics in aqueous media.

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 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. They found that separation efficiency improved with higher flow rates (reaching 78.56% at 10 m/s for 50 micrometre MPs) but decreased at higher MP volume fractions due to particle collisions, while MPs with densities below water achieved near-complete separation of 98.51%.
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.
