Abstract:
An apparatus for the destruction of microbes, or the deactivation of microbes, present in a liquid, comprising in combination:a processing chamber containing electrodes spaced apart by a given distance,at least one solid insulating barrier dividing the space within said chamber into at least two volumes,said barrier having one or more passageways such that no fluid can pass through said chamber without flowing through said passageway or passageways,a voltage source adapted to provide a pulse of voltage such that a voltage gradient effective to destroy said microbes is produced in at least some portion of the space between said electrodes, the gradient in said passageway or passageways being higher than the gradients outside said passageway or passageways,wherein each individual voltage pulse has the form of a succession of pulses having the form of a damped sinusoidal oscillation.
