Abstract
A foul-resistant, flow-through capacitor, a system employing the capacitor and a method of separation is disclosed wherein the capacitor has at least one anode and cathode electrode pair. The electrodes are formed of high surface area, electrically conductive material and have an open, preferably straight, fluid flow-through path. Typically, the flow path is formed by a plurality of straight, parallel, spaced apart electrodes with the flow path not greater than one of the X-Y-Z distance components of the capacitor. The flow-through capacitor avoids fouling in use and may be employed with saturated waste or other streams.
Claims35
A flow-through capacitor-cartridge system for use in the electrical treatment of fluids which tend to foul the capacitor of the system, which system comprises:
- a) one or more foul-resistant, flow-through capacitors, each capacitor having at least one anode and cathode pair for use in the electrical purification, concentration, separation, recovery, or electrochemical breakdown of solutes or fluids, which capacitor comprises one or more monolithic, spaced apart pairs of cathode-anode electrodes incorporating a high surface area material and having a non-conductive spacer between the anode and cathode electrodes characterized by an open flow path between the electrodes to permit the unobstructed flow of the fluid across the electrode surface and of sufficient width to prevent the fouling of the capacitor, and wherein the open flow path has at least one dimension open to an exterior of the capacitor;
- and
- b) cartridge means to seal the capacitor therein, the cartridge means having a fluid flow feed inlet and a fluid flow product outlet.
