<p>Apparatus and methods for removal of pollutants from a stream of water, by binding the pollutant particles to magnetic seeding particles using a flocculating polymer, and then removing the composite magnetic particles from the water stream in a simple and efficient apparatus. The invention is applicable to many common water treatment applications but is especially important for high flow applications requiring efficiency and simplicity. Magnetic fields concentrate the composite magnetic particles in a stratified layer that is then continually separated from the moving stream of water. In another preferred embodiment, vortex separation is combined with magnetic separation to enhance magnetic seed material cleaning and to reduce the solids load on the final magnetic collector.</p> |
