Abstract
A device for the electrodeionization of an aqueous electrolyte solution, comprises an electrodeionization module (), an ultrafiltration module () and a connection piece () which connects the electrodeionization module () and the ultrafiltration module () such as to be able to guide a diluate produced from the electrolyte solution during operation of the device in the electrodeionization module () from the electrodeionization module () to the ultrafiltration module (); wherein the connection piece () is devoid of an adjustable pressure-maintaining valve. Via the pressure drop occurring in the ultrafiltration modules (), these devices build up a counter pressure behind the electrodeionization module () which is sufficient to ensure the packing density of the ion exchanger in the electrodeionization module ().
