ClearIntegration of Photocatalysis and Membrane Technology as a Hybrid System for Microplastic Degradation in Wastewater
Researchers evaluated a hybrid system combining TiO2 photocatalysis with membrane filtration for degrading microplastics in wastewater.

Photocatalytic and biological technologies for elimination of microplastics in water: Current status
This review examines emerging photocatalytic and biological technologies for breaking down microplastics in water, since conventional treatment facilities can capture but not fully destroy these particles. Researchers found that while photocatalysis and microbial degradation show promise, their effectiveness varies widely and the underlying mechanisms are only partly understood. The study highlights the urgent need for more efficient solutions to eliminate rather than simply filter out microplastic pollution from water supplies.

Researchers tested a two-step water treatment process combining ozonation with flocculation to remove microplastics. They found that ozone pretreatment roughened the microplastic surfaces and added chemical groups that dramatically improved removal rates, from 40% to 91%, during the subsequent flocculation step. The findings suggest this combined approach could significantly enhance microplastic removal in conventional water treatment plants.
