Abstract
A system for the plasma treatment of a liquid is described. The system includes a storage chamber containing a liquid and a head-space, a gas source connected to a sparger positioned within the liquid, a pair of electrodes positioned within the liquid and substantially above the sparger, a microbubble generator positioned within the liquid, and a conduit between the head-space and the microbubble generator, such that gas from the head space can travel through the conduit to the microbubble generator. Also described is a method of plasma treating a liquid. The method includes the steps of positioning a liquid in a storage chamber at a volume that provides a head-space in the storage chamber, feeding a gas to a sparger that is positioned within the liquid to form a first set of bubbles in the liquid, passing the first set of bubbles between a pair of electrodes positioned within the liquid and substantially above the sparger, generating a plasma discharge between the electrodes, and feeding the gas in the head-space into a microbubble generator positioned within the liquid to form a second set of bubbles in the liquid, wherein the second set of bubbles are in the range of 0.1 to 5 mi…
