Abstract
A treatment of a liquid or slurry which combines the effects of heat, ultrasonification, and pressure to produce an effective bactericide. The ultrasonification effect is enhance 10-20 fold by the addition of pressure during the heat and ultrasonification treatment. The pressure results in enhancement of the cavitational effect. The enchance of the cavitational effect results in the heat becoming a more effective bactericide at a lower temperature and shorter duration.
