Abstract

The invention relates to a pulsed electric field sanitization system that may be used for sanitization of liquids, such as drinking water. The system optionally includes a double check valve (1326) to allow simultaneous flow of water into and out of components of the system. The system may be used in combination with other purification technologies. A further embodiment of the invention relates to a stand-alone drinking water purification device.
