Vortex-Flow-Induced Microparticle Concentration as an Effective Approach to Remove Microplastics and Other Particles from Contaminated Water
This technology is a physical method for removing microplastics from water using acoustic waves to generate vortices in a flow of water through a pipe or chamber to trap microplastics and other contaminant particles, including sub-micron particles which will be focused at the vortices’ centers. Captured particles can then be removed through sedimentation...
