The Science Behind NanO2
Based on Henry’s Law, gas solubility is a function of pressure and temperature, by increasing the pressure of the gas and liquid, such as water. As the process pressure increases, the number of gas molecules that are retained in the fluid increases. The pressurized solution that is developed can become a supersaturated emulsion of the two.
Bubbles are essential for the transfer of oxygen for effective aeration. The distribution and retention time of the bubbles are important factors in the treatment process. The size of the bubble has a direct impact on the effectiveness of aeration. Larger bubbles have a greater buoyancy factor and rise rapidly through a water column, requiring a greater depth for tanks, vessel and lagoons to provide the retention time required for oxygen transfer.
The “micro nano-bubbles” in NanO2 oxygen-water emulsions range from a few nanometers to microns in diameter, resulting in a reduced rate of rise, and minimizing losses to off gassing. This increases the time that dissolved oxygen is available for biological processes, chemical treatment and environmental remediation.
NanO2 process delivers the two-phase emulsion through high velocity injection nozzles creating a rapidly expanding cloud of micro nano-bubbles.
How NanO2 Generates Ultrafine Bubbles
The NanO2 process begins with either potable or wastewater being pressurized, then atomized and passing through a concentrated gas zone within the NanO2™ process vessel. This forms the micro nano-bubbles in the high-density two-phase solution that is discharged as determined by the process control. The process is capable of delivering a solution with dissolved oxygen content up to 40 times that of conventional aeration.
The supersaturated solution is discharged through our zone valve manifold through tubing or piping to our engineered nozzles. The nozzles are submerged at the point of treatment allowing for optimum oxygen transfer and delivery where most effective. The simple delivery system reduces cost and can be installed quickly with minimal tools or labor.
The key to our efficient aeration process are the NanO2 nozzles that create high velocity liquid discharge to deliver the high concentrations of dissolved gases without the formation of larger buoyant bubbles. The majority of the micro nano-bubbles range from a few nano-meters to few microns in size.
