Abstract

Diaphragm comprises or is coated with an electrically conducting material. An independent claim is also included for a water purifying module containing the above diaphragm.

Description

Die vorliegende Erfindung betrifft ein Diaphragma für ein Wasserveredelungsmodul nach dem Oberbegriff des Anspruchs 1.The The present invention relates to a diaphragm for a water treatment module according to the preamble of claim 1.

Derartige Diaphragmen dienen dazu, als permeable Barrieren, Trinkwasserströme in Wasserveredelungsmodulen zu trennen und zu kanalisieren. Sie werden zwischen der Anode und der Kathode eines Wasserveredelungsmoduls angeordnet. Die Wasserveredelungsmodule können ein Teil eines Trinkwasserspenders darstellen. Das Trinkwasser durchströmt den Bereich der Anode und den Bereich der Kathode, wobei der sogenannte Kathodenprozess räumlich und zeitlich getrennt von dem Anodenprozess abläuft.such Diaphragms serve, as permeable barriers, drinking water streams in water treatment modules to separate and channel. They are between the anode and arranged the cathode of a water treatment module. The water refining modules can represent a part of a drinking water dispenser. The drinking water flows through the area the anode and the region of the cathode, the so-called cathode process spatial and time separated from the anode process expires.

Die bisher für diesen Zweck eingesetzten Diaphragmen bestehen aus formstabilen Teilen aus einem wasserdurchlässigen Material, welches den elektrischen Strom nicht leitet. Der Ionenfluss durch das Diaphragma wird nur durch die an Anode und der Kathode angelegte Spannung beeinflusst.The so far for diaphragms used for this purpose consist of dimensionally stable Parts of a water-permeable Material that does not conduct electricity. The ion flux through the diaphragm is only by the anode and the cathode applied voltage influenced.

Gegenüber den bekannten Diaphragmen hat das erfindungsgemäße Diaphragma den Vorteil, dass es aus einem elektrisch leitenden Material besteht oder mit einem elektrisch leitenden Material beschichtet ist. Ein mit diesem Diaphragma ausgestattetes Wasserveredelungsmodul ist zur Verbesserung der Wasserqualität vorgesehen.Compared to the known diaphragms, the diaphragm according to the invention has the advantage that it consists of an electrically conductive material or with a electrically conductive material is coated. One with this diaphragm equipped water treatment module is designed to improve water quality.

Beispiele für Materialien, aus denen das Diaphragma besteht, sind Keramik mit einem aufgedampften leitfähigen Material oder ein leitfähiges Kunststoff-Flies.Examples for materials, which make up the diaphragm are ceramics with a vapor-deposited conductive Material or a conductive plastic tile.

Nach einer vorteilhaften Ausgestaltung der Erfindung ist das Diaphragma mit einem elektrischen Anschluss ausgestattet, um das Diaphragma an eine Spannungsquelle anzuschließen.To An advantageous embodiment of the invention is the diaphragm equipped with an electrical connection to the diaphragm to connect to a voltage source.

Durch eine weitere vorteilhafte Ausgestaltung der Erfindung ist die Stromversorgung des Diaphragmas in den Spannungsregelkreis der Anode und der Kathode integriert und separat ansteuerbar.By A further advantageous embodiment of the invention is the power supply of the diaphragm into the voltage control loop of the anode and the cathode integrated and separately controllable.

Dank der Stromversorgung kann das Potential des Diaphragmas eingestellt werden. Die Potentialdifferenz zwischen der Anode des Wasserveredelungsmoduls und dem Diaphragma einerseits und der Kathode des Wasserveredelungsmoduls und dem Diaphragma andererseits bewirkt eine Beschleunigung der in dem Wasser zwischen der Anode und der Kathode enthaltenen Ionen. Dadurch wird der Ionenfluss zwischen der Anode und der Kathode und dem Diaphragma zusätzlich durch das Diaphragma beeinflusst.thanks the power supply can adjust the potential of the diaphragm become. The potential difference between the anode of the water refining module and the diaphragm on the one hand and the cathode of the water refining module on the other hand and the diaphragm on the other hand causes an acceleration of the in the water between the anode and the cathode contained ions. As a result, the ion flux between the anode and the cathode and the diaphragm in addition influenced by the diaphragm.

Der Einfluss des Diaphragmas soll ermöglichen, differenziert negative und positive Ionen aus dem Wasser zu eliminieren. Die Stärke des Einflusses des Diaphragmas hängt von der an dem Diaphragma angelegten Spannung ab.Of the Influence of the diaphragm should allow differentiated negative and to eliminate positive ions from the water. The strength of the Influence of the diaphragm hangs from the voltage applied to the diaphragm.

Die Erfindung betrifft darüber hinaus ein Wasserveredelungsmodul mit einem oben beschriebenen Diaphragma, ein Verfahren zur Wasserveredelung mit einem solchen Wasserveredelungsmodul sowie dem durch ein solches Wasserveredelungsmodul behandeltes Wasser.The Invention relates to this In addition, a water treatment module with a diaphragm described above, a method for water refining with such a water refining module and the treated by such a water treatment module water.
