Abstract: 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.

Abstract: 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.

Abstract: The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump. The ozone and the oxygen are turned into ultra-fine bubbles via cavitation action within the pump, facilitating the dissolution of the oxygen and ozone within the water. The water mixed with the oxygen and the ozone is subsequently supplied to a line atomizer, where the dissolution of the ozone within the mixture is completed. The combined use of the cavitation pump and the line atomizer can lead to a substantially complete dissolution of the supplied ozone within water that needs to be disinfected, allowing to easily achieve the concentration of ozone necessary for water disinfection. Due to this efficiency, the system and method described are highly scalable and suitable for water purification at water purification plants of various sizes.
