Abstract
A flow-through capacitor and method for the purification of fluids, like soft water. The capacitor includes anode-cathode electrodes (3) composed of a low surface area electrode material having a surface area between 10 to 1000 square meter per gram BET (Brunauer Emmett Teller method) to form one or more cells.
Claims19
A flow-through capacitor comprising:
- a) a housing comprising an inlet for the introduction of a fluid and an outlet for the withdrawal of a fluid;
- and
- b) a plurality of anode-cathode electrode layers to form a cell within the housing, the electrode layers comprising an electrode material having a capacitance of above about 1 farad per gram capacitance, the layers arranged and constructed to provide for the flow of the fluid between the layers and through the cell;
- wherein the flow-through capacitor has a series resistance per individual cell of about 0.03 ohms or less.
