ABSTRACT:
Polarizable particulate material, such as organic and inorganic colloidal particles such as small pieces of metal, oxides and the like, zwitterionic molecules, and even living organisms and viruses can be preferentially removed from a liquid by dielectrophoresis, by passing the liquid containing the polarizable particulate material to be removed over a ferroelectric apparatus which generates a periodic non-uniform electric field near the boundary between alternately polarized portions of the ferroelectric material. The periodic non-uniform electric field is generated by subjecting portions of the ferroelectric material to an alternating potential to alternately polarize the portions, while allowing other portions of the ferroelectric material to remain polarized in the same direction.
