1. An electrodeionization apparatus comprising an assembled ion exchange membrane stack, means for transferring a suspension of ion exchange particulates in a fluid into at least one of the chambers of said ion exchange membrane stack, strainers within said chamber for retaining said particulates within said chamber to at least partially form a packed bed of particulates therein, said chamber further comprising at least one fluid flow path, said path having at least one first channel communicating with a first fluid transfer manifold adapted to transfer fluid into or out of said flow path, said path also having at least one second channel communicating with a second fluid transfer manifold adapted to transfer fluid into or out of said flowpath, said flow path also having at least one flow path width restrictor intermediate between said first channel and said second channel, said restrictor further having at least one third channel communicating with a fluid transfer manifold adapted to transfer fluid into or out of said flow path.
