System and method for altering characteristics of materials using an electrohydraulic discharge
Abstract
System and method for oxidizing contaminants to alter specific properties, such as tack, of contaminants. The present invention reduces the tack of the stickies and pitch by exposing the materials for a short duration to low-energy pulsed electrical discharges between a pair of electrodes that are submerged in a liquid medium, such as a fiber stream, water, a pulp slurry, or whitewater. An electrical discharge in the liquid medium oxidizes materials, which may be dissolved or suspended therein, such as stickies, pitch, sulfide, ink, toner, and other substances, thereby reducing tack, odor, and/or zeta potential, as well as producing other desirable effect.
