Increased control and efficiency over the wastewater purification can be achieved through creating conditions that allow the operator 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 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 biodegradable material in the gas-dispersion return sludge, the microorganism prioritize their digestive function, and when exposed to biodegradable pollutants present in wastewater, digest the pollutants using biochemical pathways different from the ones used in nature.

The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump or a line atomizer. A compressor can be introduced at an inlet of the cavitation pump or the line atomizer, compressing the gas mixture at a pressure higher than the pressure within pump or the atomizer. The compressed gases are provided to the inlet of the atomizer or the pump, where the compressed gases mix with the water and enter the cavitation pump or the line atomizer (where most of the dissolution of the gases happens). The compressor allows to increase the amount of oxygen and ozone provided to the pump or the line atomizer, increasing their dissolved concentration. In addition to the disinfecting properties, the higher level of oxygen correlates to an improved taste of the water.

Provided is a method for manufacturing an active material mixture, the method including: supplying and dispersing a solid electrolyte in a dispersion medium while circulating the dispersion medium (a first dispersion step); and thereafter supplying and dispersing an active material and a conductive material in the dispersion medium (a second dispersion step), wherein an average rotation speed of the rotor in the second dispersion step is lower than an average rotation speed of the rotor in the first dispersion step. Aggregation of the solid electrolyte can be suppressed by separately performing the first dispersion step and the second dispersion step, and the increase in temperature of the active material mixture can be reduced by lowering the rotation speed of the rotor in the second dispersion step.

A method is provided for producing fine-bubble water by resonance foaming and vacuum cavitation, and a device for manufacturing each of ultra-fine-bubble water of hydrogen gas having a reducing radical function, ultra-fine-bubble water of air and oxygen gas having an oxidizing radical function, ozone ultra-fine-bubble water having a sterilization function enabled by ozone, and fine-bubble water of nitrogen/carbon dioxide gas for increasing the ability to preserve the freshness of raw agricultural products, livestock products, and marine products.

A nano-bubble water generating apparatus containing an application gas includes a motor, a pump integrated with the motor for supplying liquid, typically water, from an inlet pipe under a predetermined pressure through a supplying pipe to a pressure tank, a nano-bubble water generating tube mounted at the water entrance of a pressure tank, an electronic control portion, a pressure adjuster including an outer air inflowing portion to introduce an outer air or a specific gas supplied thereinto to control a pressure in the pressure tank, uniformly and a pressure adjusting portion airtightly coupled on the upper portion of the outer air inflowing portion to adjust an amount of outer air or specific gas to be supplied, and a nano-bubble water expanding tube for expanding and shattering nano-bubble water through an outlet pipe from the pressure tank, so that the size of the nano-bubble water is better micronized.
