Disclosed is an apparatus for separating a polar ionic substance, such as nitrate nitrogen (NO), from groundwater or a water supply and concentrating the separated substance. The apparatus includes a case having an inlet formed so that the fluid can flow into the case, a diluted fluid outlet formed so that the fluid can be discharged after the fluid has been diluted by separating the polar substance from the fluid, and a concentrated fluid outlet formed so that the fluid can be discharged, the separated polar substance having been concentrated in the fluid; an anode and a cathode installed inside the case while being spaced from each other and supplied with external power; and at least one spacer having pores formed so that the fluid and the polar substance can pass through, the spacer being positioned between the anode and the cathode to divide a space between the anode and the cathode into a diluting chamber and a concentrating chamber, the diluting chamber communicating with the inlet and the diluted fluid outlet, the concentrating chamber communicating with the concentrated fluid outlet. The polar substance contained in the fluid inside the diluting chamber is moved to the concentrating chamber through the at least one spacer by a difference in electric potential between the anode and the cathode so that the polar substance is separated and discharged.
