Abstract
Electrodeionization packing including one or more macrostructural elements made up of smaller, microstructural elements. The microstructural elements are in fixed, close contacting position with respect to each other in the macrostructural elements so as to provide porosity in the macrostructural elements. A majority of the microstructural elements have a characteristic dimension between 10 and 50 micrometers, and the macrostructural elements have a void fraction between about 25% and 50%.
