1. for generation of an electrodialysis methods for the cushioning liquid of modification, described method comprises:

  • (a) make flow through under the pressure that is less than about 30psi modification buffer of cushioning liquid under a kind of concentration that is greater than about 10mM, that comprise cation and anion produce flow channel;

    (b) make flow through ion of a kind of aqueous liquid stream receive flow channel, this ion receives flow channel to be separated with described modification buffer flow channel by a first ion-exchange barrier, this the first ion-exchange barrier comprises tradable cation or anion, but comprise both when different, and can block bulk liquid and flow, described film has and is greater than approximately 0.5 inch 2surface area;

    And (c) electric current is passed between first and second electrode across described modification buffer mobile generation passage and described ion reception flow channel, to make cation or anion, but not both, be transmitted through described the first ion-exchange barrier to produce a kind of cushioning liquid of modification, the cushioning liquid of this modification produces flow channel from described modification buffer and flows out.
