Caption

Prototypes of toothed drums for different types of MP recovery / (A) The experimental image shows the MP skimming process using a toothed structure drum with P = H = 6 mm and a drum diameter of 60 mm. The drum skims millimeter-sized PE pellets and micrometer-sized PE particles. (B) Shows how the toothed drum removes all MPs located on the right side of the bath, and then releases them to the left, regardless of whether the MPs are i) PE pellets with a size of 2-4 mm, or ii) PE particles in the range of 1-2000 μm (C). (D) The recovery seen by the toothed drum at three different drum rotation speeds for five different MPs.
