Revolutionary Nanobubble
Technology

Nanobubble is a bubble with a diameter of less than 1 micrometer. Nanobubble is also called “ultrafine bubble”.

Nanobubbles are extremely small in diameter and rise through liquid at a very slow rate. According to Stoke’s Law, the flotation velocity of a bubble with a diameter of 100 nm is less than 1 mm per day. Nanobubbles also exhibit very high internal pressure. Based on the Young–Laplace equation, the internal pressure of a 100 nm bubble is about 10 times greater than that of a 1000 nm bubble. This elevated internal pressure enhances the solubility of the gas contained within the bubble. As a result, nanobubbles are uniquely characterized by an exceptionally high gas solubility rate, attributed to both their slow flotation velocity and high internal pressure

At atmospheric pressure, the volume of nanobubbles gradually decreases over time, although some can persist for several months. However, once their volume is significantly reduced, the unique characteristics of nanobubbles are lost. Since the rate of volume reduction is most rapid immediately after generation, it is recommended to use nanobubbles within 24 hours of their formation.

Nanobubbles generated with air do not possess sufficient oxidizing power. To achieve effective oxidation or sterilization, ozone should be used instead of air. Although some assume that oxidative power arises from the explosive collapse of nanobubbles, the magnitude of this effect is negligible and therefore insignificant.

Each bubble size serves a different purpose. Microbubbles are advantageous for floating suspended solids or oil, while macrobubbles are effective for circulating water. Nanobubbles, on the other hand, have an extremely slow flotation rate, making them unsuitable for use as flotation or circulation devices. It is often the case that devices advertised as nanobubble flotation systems are actually generating microbubbles, not genuine nanobubbles.

It is a device that creates nano-sized bubbles within a liquid. It is not a device that sprays only bubbles like an aerator, but a device that effluents the liquid in which nanobubbles exist.

The oxygen content of air is 21%, whereas an oxygen generator can provide gas with 90% oxygen concentration. For the same gas volume, the oxygen supplied by the generator is approximately four times greater. In our device, the component that consumes the most power is the pump, while the oxygen generator requires only about 25% of the pump’s power consumption. In other words, by increasing power input by just 25%, the dissolved oxygen can be increased fourfold. Consequently, using an oxygen generator is significantly more economical than using air.

Yes, however, reducing the diameter of nanobubbles may not be cost-effective. Producing nanobubbles with an average diameter below 100 nm requires a substantial amount of energy, yet the resulting increase in dissolved oxygen is not proportional to the energy expended. Among the methods for enhancing dissolved oxygen, it is more economical to slightly increase the oxygen injection rate than to focus on producing smaller nanobubbles.

Yes. When nanobubbles collide with solid surfaces, they transition into microbubbles, which help detach contaminants from the surface. In tests conducted on the slime in cooling water pipes, the presence of nanobubbles effectively prevented slime formation.
