Ultra-Oxygen (UO2) – Micro and Ultrafine Bubble (MB/UFB) high-quality PVC generators.

How the 1N-PVC MB/UFB generator works:

The water is pushed from the outer shell chamber into the gas-liquid mixing chamber via holes in the top of the inner chamber that force the water to spin inside this chamber at a very high speed downwards (first vortex). The floor of the chamber pushes the water up creating a second vortex upwards in the opposite direction through the centre of the first vortex, and then pushing the water out of the hole in the top of the gas-liquid mixing chamber ceiling.

The high velocity creates a negative-pressure cavity portion at the bottom of the inner chamber floor, naturally sucking in the air via the air supply line.

Micro and Ultrafine bubbles are created due to the shearing action of the swirling flow generated by the water squirted into the gas-liquid generating chamber.

The concentration of Micro and Ultrafine bubbles can be adjusted by increasing the negative pressure in the gas-liquid mixing chamber via the gas supply line.

How the VIPER MB/UFB generators work:

The VIPER MB/UFB generator works side by side with the 1N-PVC MB/UFB generator. This addition was designed to enable engineers to multitask like never seen before in the world.

Combining the functions of an ejector, injector, jet pump, vacuum generator, and venturi, enabled the VIPER to generate micro- and ultrafine bubbles, to add a gas in a liquid, to add a liquid to a liquid, to use cavitation to assist with disinfection, and to improve the quality of mixing in of nutrients in water.

In short, water flows into the VIPER at a higher pressure than that at which it exits. This pressure difference creates a vacuum at the suction port on the side of the device. This sucks air, oxygen, ozone, or liquid into the main water stream. So, the greater the difference in pressure, the greater the vacuum and, with that, the greater the efficiency of mixing.

What makes the VIPER unique is that in venturis gas and liquid are pulled, via a hole unevenly, into a single mixing vortex, whereas in the Viper’s case, the gas or liquid is received by a large suction chamber and feeds this evenly via the perimeter of the entrance hole of the diffuser that leads through to the diverging cone.

In the VIPER the static pressures in the suction, and mixing zone chambers, can be decreased below the vapour pressure by as much as -90 kPa at a constant flow of water by reducing the airflow to the suction chamber, allowing water to evaporate in the formation of bubbles (Vapor bubble grows at low pressure). It collapses within milliseconds again in a spectacular physical event as it is transported with the flow from where it was formed at low pressure to areas with higher pressure. The bubble will stop growing when local pressure exceeds vapour pressure and because liquid water occupies many thousand times less volume than vapour, the bubble implodes.

Also known as cavitation, the water is forced to become water vapour by the physical creation of micro vacuums “bubbles” underwater. These “bubbles” are made of water vapour only. No air or gasses are involved. These “bubbles” fully collapse to again form liquid water. The jet velocity can reach up to hundreds of m/s.

It must be noted that cavitation on its own, DO NOT INCREASE DO LEVELS in water. However, due to the ability to create a negative pressure up to -90 kPa in the suction chamber, the VIPER MB/UFB generator can raise DO levels and use Cavitation at the same time in the water with a temperature of 10 degrees Celsius.

In general, cavitation is one of the elements of an integrated treatment system, consisting of physical, chemical, and biological processes.

The effects of cavitation have become very useful in supporting chemical processes in environmental protection technologies, especially in technologies related to the decomposition of substances particularly harmful to humans and their immediate surroundings.

Benefits expected: Improves coagulation and flocculation, drops zeta potential, increases oxidation potential that helps to remove bacteria and parasites, rapture their cell walls, and then kills them by oxidation. It increases the biodegradability of organic compounds in polluted water. Exhibit bactericidal activity during water treatment. Decrease the amount of persistent organic pollutants in wastewater treatment plant effluent. Biological disinfection of water. Destructive effect on yeast, bacteria and even viruses. The combination of cavitation and H2O2 for example, gives a higher reduction in suspended TOC values of tannery wastewater than only using H2O2.

Conclusion:

Oxygen is a necessary element in all forms of life. The level of dissolved oxygen (DO) is one of the best indicators of overall water quality.

The dissolution of oxygen into the water is maximized with the injection of UO2 micro- and ultrafine bubbles. This is because small bubbles present a greater relative surface area to the surrounding water than larger bubbles. Oxygen diffuses into the water at the surface, so a large surface area facilitates greater oxygen absorption.

Knowing that the oxygen transfer efficiency decreased as the water jet velocity increases and that the energy needed to increase the jet velocity, the focus on the highest oxygen transfer efficiency was compromised in the design to incorporate the practical elements and to achieve the best of all worlds into one.

UO2-MB/UFB generators are the best-priced, most cost-effective, sustainable, robust, easy to use, and most environmentally friendly way in the world, to create bubbles smaller than 100 microns.

On top of this, being able to also use the new advanced technology of hydrodynamic cavitation in environmental engineering, allows Ultra-Oxygen to provide solutions in processes greatly effective during water and effluent treatment.

Hydrodynamic cavitation is a non-wasted technology and environmentally friendly due to the possibility of degradation of low biodegradable, hazardous and carcinogenic organic compounds, which are resistant to conventional disposal methods.

Examples include pesticides, dyes, or high molecular organic compounds, which in the cavitating liquid environment become susceptible to biodegradation.

Ultra-Oxygen believes that MB/UFB and hydrodynamic cavitation is the most energy-efficient technique in the world in any AOP or water treatment process.

It can diminish the recently necessary use of expensive chemical reagents for advanced treatment processes. These chemicals create additional problems when deposited into the environment.

Finally, nowadays a lot of attention is put upon micropollutants such as endocrine-disrupting compounds, chemicals that can interfere with endocrine (or hormonal) systems. Endocrine systems are found in most varieties of animals. The endocrine system consists of glands that secrete hormones, and receptors that detect and react to the hormones.

Studies in cells and laboratory animals have shown that EDCs can cause adverse biological effects in animals, and low-level exposures may also cause similar effects in human beings. EDCs in the environment may also be related to reproductive and infertility problems in wildlife and bans and restrictions on their use have been associated with a reduction in health problems and the recovery of some wildlife populations. Aquatic life subjected to endocrine disruptors in an urban effluent has experienced decreased levels of serotonin and increased feminization.

Ultra-Oxygen is proud of itself for being able to provide a solution that can deal with micropollutants.

What UO2-MB/UFB generator, and how many do I need?

To answer this question we suggest you contact us. In short, to answer your question we will need to know what the DO level is in your system, the quality of your water, the maximum value you use in a day and during what time of the day, the amount of water you keep in storage, and what DO levels would like to see in your system.

Our project-specific engineering services will cover all above.
