An apparatus for modifying a responsive liquid held in a barrel or other liquid container includes a transducer for producing vibration energy within the audio frequency range in response to an audio signal input and a coupler affixed to the transducer such that vibration energy produced in the transducer is transferred to the coupling device. The coupling device has a pusher end that extends beyond the front plane of the transducer and that contacts and pushes against the barrel wall when the apparatus is tied to the barrel wall. By determining the resonances of the liquid-filled barrel, audio input signals having sufficiently high levels at determined resonant frequencies can be chosen to achieve a maximum response in the liquid contained in the barrel. The apparatus is particularly suited for the sonic aging of whisky.

The present technology discloses a cost-effective, single use bag or container for storing biological substances that incorporates on its inner wall an electronic device that is configured to measure physiological and/or physical parameters of the enclosed biological substances, such as source history, identification, demographics, time stamping, temperature, pH, conductivity, glucose, O.sub.2, CO.sub.2 levels etc. The electronic device of the disclosed bag comprises a sensor configured to measure physiological and/or physical parameters of the biological substances enclosed within the bag, and a radio-frequency (RF) device communicably coupled to the sensor and configured to: (a) acquire from the sensor data associated with the measured parameters, (b) store the acquired sensor data in nonvolatile memory, and (c) communicate the stored data wirelessly to a RF reader.

Increased control and efficiency over the wastewater purification can be achieved through creating conditions that allow to selectively prioritize the digestive function of microorganism in the activated sludge. The gas-dispersion return sludge is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas, which is blended with return sludge to create a mixture of gas and liquid, which is passed through an atomizer or a cavitation pump to instantly render the reactive gas in the mixture to an ultra-fine bubble state. At least a portion of the ultra-fine bubbles dissolve within the gas-dispersion return sludge, activating the dormant microorganisms. Due to a complete or an almost complete absence of digestable organic material in the gas-dispersion return sludge, the microorganism prioritize their digestive function, and when exposed to organic pollutants present in wastewater, digest the pollutants into water and carbon dioxide at an increased rate.

Provided is a bubble volume control method and apparatus, and more particularly, to a bubble volume control method and apparatus for controlling the volume of a bubble by increasing or decreasing the volume of the bubble by emitting an ultrasonic wave having a resonance frequency corresponding to the size of the bubble located at the bottom of a container containing a liquid, such as water with bubbles composed of air, vapor, etc., toward the bubble by using an ultrasonic generator above the container, and maximizing a function of adjusting the volume of a bubble through a resonance effect by adjusting a liquid surface height of a liquid with the bubble according to a wavelength of an emitted ultrasonic wave.

Control over the wastewater purification can be achieved through controlling delivery of gas-dispersion return sludge solely to an aerobic reaction vessel. The gas-dispersion return sludge is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas, which is blended with return sludge to create a mixture of gas and liquid, which is pressurized with an atomizer pump, and then at a pressure of not more than approximately 5.5 MPa, the mixture is passed through an atomizer which uses cavitation or ultrasound at a frequency of less than 12,000 KHz to instantly render the reactive gas in the mixture to an ultra-fine bubble state. A portion of the gas is placed into a dissolved state, reaching a state of supersaturation with a high DO value of 20-40 mg/l, and causing the remaining ultra-fine bubbles to create an ultra-fine bubble condition.

The proposed multifunctional hydrodynamic vortex type reactor includesa housing having curvilinear inner sidewalls,a base attached to the housing, an inverse taper narrowing downward and attached to the top of housing,a supporting tube passing at least through the housing and base,a set of washers tapered downward and mounted on an outer surface of the supporting tube such that outer upper edges of the set of washers and the inner sidewalls form predetermined gaps therebetween, anda number of inlets tangentially attached to the base for introducing, under external pressure, a solid substance and a liquid (or a suspension of their mixture) thereinto, forming a circulating flow therein. The flow forms a high speed bypassing cavitation zone and, changing its direction at the inverse taper, forms a vortex cavitation zone, providing for mixing and grinding the substance up to nanoscale sizes. Methods for intensifying cavitation are also provided.

The present application relates to ultrasonic technology, and discloses an ultrasonic beer bubbling container with a good bubble foaming effect and less energy loss. The ultrasonic beer bubbling container comprises a cup body for containing beer and a base provided on the bottom of the cup body. The cup body and the base are separable; an ultrasonic vibrator is arranged in the base, and a through-hole is formed on the bottom of the cup body; wherein a part of the ultrasonic vibrator goes through the through-hole and extends to the cup body, thus to produce ultrasound and directly vibrate the beer so as to foam the beer.
