Novel Separation Technology: Selective Removal of Suspended Particles from Raw Waters

This article describes a novel approach for removal of suspended particles from source waters that operate purely by fluid dynamics without the need for a physical barrier. This technology uses centrifugal force to create transverse flow patterns in a curved channel to concentrate suspended particles above a designed cut-off size into a narrow band. Unlike existing hydrocyclones and centrifuges, which require particles in the suspension to have a different density from the liquid medium, this technology can also address neutrally buoyant suspensions.
