AI Technical Summary
Existing microplastic removal devices in water lack pre-filtration functions, which leads to large particles of impurities clogging the screen and reducing the efficiency and effectiveness of microplastic removal.
It adopts a pre-screening filtration component and a multi-stage screening component, including a loading guide plate, filter bag and multi-stage screening screen, to screen microplastics in water step by step through multi-stage filtration, pre-filter large particulate impurities and improve screening efficiency.
It effectively filters large particles of impurities, prevents screen clogging, improves the removal efficiency and effectiveness of microplastics in water, and reduces maintenance costs.
