  • Separation of Solids and Fluids by Magnetic Flocculation

    Flocculation, the process of coagulation or coalescence of finely divided particles, is commonly used in separating fine solids from fluids Forces disposing of the particles to flocculate include: ionic forces of attraction, secondary entropic forces, and magnetism Magnetic flocculation is due to a physical magnetizing process which affects suspended ferromagnetic particles Such particlesMagnetic flocculation separation occurs as a result of diverse colloidal forces acting on paramagnetic particles in the liquid flow field in the presence of an external field Primary forces acting on individual particles, including external forces such as magnetic attraction, gravitational forces, and interparticle forces which act between two particles change in strength when one particle approachesA review of principles and applications of magneticMagnetic flocculation thus represents a general platform and alternative paradigm for nanoparticle separation, with potential applications in water treatment and remediation of nanoparticle pollution Furthermore, given that flocculant chemicals can be recovered and reused in this process, magnetic flocculation may also serve as an environmentally sustainable solution to conventional flocculationMagnetic flocculation for nanoparticle separation and
