To provide a method and apparatus of simple construction for separating charged impurities in a fluid that can separate charged impurities contained in a liquid or gas.
The apparatus is equipped with an electrophoresis vessel 7a where a fluid 1 to be treated containing charged impurities 3, 4, 5 and 6 is introduced and a treated fluid 2 free from the above impurities is generated, while separation fluids 41, 42, 43 and 44 containing the only impurities among the above impurities that have either positive or negative charge polarity and a specified range of at least one of particle size and electrophoretic velocity thereof, are formed. The above electrophoresis vessel is comprised of a treated-fluid chamber 30 where the above fluid to be treated is introduced and the above treated fluid is generated as well as separation-fluid chambers 31, 32, 33 and 34 that are located adjacent to the above treated-fluid chamber with diffusion layers 11, 12, 25 and 26 which is permeable to fluid components of the fluid to be treated to suppress a diffusion of the above impurities positioned between them, equipped with electrodes 8 and 9 to form an electric field acting on the above impurities, and form the above separation fluid.
