Abstract
A method and apparatus for treatment of a fluid medium to inactivate biocontamination using a pulsed electric field (PEF). A fluid medium is pumped through a treatment assembly to treat the fluid medium. A pulse generating system produces input pulses of high voltage that are supplied to the treatment assembly. A pulsed high intensity electric field associated with the input pulses is produced in a treatment assembly. As the fluid medium flows through the treatment assembly, it is exposed to the high intensity electric field, thereby treating the fluid medium. The pulse generating system includes a pulse compressor to reduce the rise time of the high voltage pulses supplied to the treatment assembly, and forming a pulsed electric field in space, without use of an electrode system.
