In work the asymptotic solution of the regional task modeling transfer of ions of salt in the camera of an obessolivaniye of the electrodialysis device is proposed. For this purpose the area of the camera of an obessolivaniye breaks into two subareas: the area of an electroneutrality and area of a spatial charge, in each of which, asymptotic decomposition has the appearance. Feature of the proposed asymptotic solution is that in the field of a spatial charge for unambiguous resolvability of the current approach the condition of resolvability of the following approach is used. For the numerical realization, the proposed asymptotic solution the differential operator who in the field of an electroneutrality is elliptic, and in the field of a spatial charge parabolic is formulated. For sampling obvious and implicit differential schemes are used. The example of the numerical decision is given.
