16-14: Controlled Hydrodynamic Cavitation: A Physical Water SofteningCavitation has long been known to be a powerful force usually associated with unwanted destruction of system components. Controlled cavitation however can yield to beneficial outcomes when applied to water treatment for cooling towers. Cavitation forces calcium to be removed creating a mechanical softener that also destroys bacteria. This redirection of force is currently being employed to eliminate scaling and biofouling successfully in cooling
