ABSTRACT:
Devices and methods for treating, preventing from growth, and neutralizing microorganisms in cooling fluids utilized in tire manufacturing, using high-frequency, low-energy ultrasound. In one embodiment, a method includes simultaneously exposing said cooling fluid to gas and high-frequency ultrasound. In another embodiment, a device includes a compartment for holding a reservoir of tire manufacturing cooling fluid, an ultrasound emitter configured to emit high-frequency ultrasound signals into the compartment, and a gas emitter configured to emit gas into the ultrasound field in the compartment containing the cooling fluid.
