Abstract:
1. An electrodialysis apparatus comprising: an electrodialysis stack; a pair of electrode grates, the electrodialysis stack positioned between the pair of electrode grates; a pair of electrodes, wherein the electrodialysis stack and the pair of electrode grates are all positioned between the pair of electrodes; and a housing configured to pressurize the electrodialysis stack at a stack pressure, the housing including a cell chamber configured to receive the electrodialysis stack, the cell chamber including at least one pressurization port communicating with the cell chamber such that a portion of an electrode solution is transmittable into a region of the cell chamber outside the electrodialysis stack, wherein each electrode grate of the pair of electrode grates comprises a spacing rim configured to raise the electrode grate face away from an electrode of the pair of electrodes.
