Dissolved Oxygen Solutions

Waste Water

UO2-MB/UFB aeration is used in water and wastewater treatment processes to deliver dissolved oxygen to microorganisms responsible for the biological oxidation of carbonaceous material and ammonia. 


Micro and Ultrafine bubbles enable the cost-effective use of dissolved oxygen to improve water quality to help repair soil, promote nutrient uptake, increase plant health, and suppress root disease. 


When fish populations are tightly packed, a shortage of dissolved oxygen is inevitable because the fish and shellfish consume more oxygen from the water. Improving water quality sustainably for reuse is a major advantage for farmers.

MICRO and ULTRA-FINE BUBBLES ARE extremely small gas bubbles that have several unique physical properties that make them very different from normal bubbles.

These properties make UFB-Ultra Fine Bubbles a SUPERIOR AERATION method for several applications around the world.

Ultra-OXYGEN provides solutions that include the latest award-winning patented aeration technology in the world to increase the dissolved oxygen (DO) in water at rates and speeds never been seen before.

Beyond Nanobubbles??

The devising or choosing of names for things, especially in science or other disciplines, is important. Using it correctly even more.

Lucky for us as professionals, we have organizations such as ISO (The International Organization for Standardization is an international standard development organization composed of representatives from the national standards organizations of +-130 member countries, founded in UK, 23 February 1947.), helping us.

ISO-20480-1 First edition 2017-065 – Annex A extract:

ISO/TC 281 recognizes that the term “nanobubble” is commonly used to mean “ultrafine bubble”. However, “nanobubble” is not defined clearly, and thus the use of “ultrafine bubble” is strongly preferred. ISO/TC 229 defines nano-objects as having a size less than 100 nm. Although nano-objects are specified as 100 nm or less in ISO/TS 80004-1, there is no scientific or convincing evidence for the time being that there is a difference in the physical phenomena of ultrafine bubbles with the dividing line of 100 nm.

Therefore, ISO/TC 281 does not use the term “nanobubble”.

The above is very clear, it is incorrect to tell the world that “nanobubbles” are the only bubbles with recognized special characteristics.

There are, however, no dispute among professionals that the surface tension driving bubbles to go smaller and collapse are special and useful.


Ultra-Oxygen would like to make you aware of Laplace’s law as it applies to bubbles, when they are collapsible, and how the depth of the water influences it.

As an aeration specialist in the civil engineering field for 30 years, I agree with ISO that “nanobubbles” do not have the right to claim they are superior to the other bubbles that is also collapsible and have the same special characteristics. The range of bubbles deserve equal credit.

Micro Miracle: The Power of MB/UFBs

Introducing the game-changers

Ultra-Oxygen Micro and Ultrafine Bubbles. These minuscule wonders, measured in micro and nanometers, pack a punch like no other. Thanks to their petite size, they’re armed with higher internal pressure – the magic ingredient that sets the stage for a cavitation extravaganza. Remember Laplace’s law? Smaller bubbles mean greater internal pressure, which translates to a symphony of implosion, the core act of cavitation.

Depth (m)Pressure (Pa)Laplace’s Law FactorImploding Bubble Size (μm)Hypothetical Zeta Potential (mV)Internal Pressure (Pa)
Imploding Bubbles is possible from ~192 μm @ 0.5 m depth – going deeper, the bubble must be smaller.

The Great Debate: MB/UFBs vs. Nanobubbles

Hold onto your hats, folks! Ultra-Oxygen Micro and Ultrafine Bubbles are not just catching up with nanobubbles – they’re taking the lead. While nanobubbles hog the limelight, expensive nanobubble generators often overshadow the real stars – MB/UFBs. These tiny marvels boast implosion superpowers, ushering in a fluid frenzy, turbocharged mass transfer, and a perfect stage for chemical reactions. Imagine an orchestra where the underdogs hit the highest notes, leaving the audience spellbound.

A Glimpse into Tomorrow: The MB/UFB Revolution

The future of water treatment and environmental harmony is shaped by innovation that’s as effective as it is efficient. Nature whispers the tale of UFBs, from crashing waves to babbling brooks, showcasing their prowess. By tapping into the potential of Ultra-Oxygen Micro and Ultrafine Bubbles, we’re ushering in an era of sustainable solutions that don’t break the bank.

Let’s widen our gaze beyond the microcosm of nanobubbles and embrace the incredible universe of Ultra-Oxygen Micro and Ultrafine Bubbles. These minuscule heroes are rewriting the story of water treatment, leaving an impact that far exceeds their size.

Breaking News for Water Engineers


All references made to “fine bubbles” in any technical documentation published before mid-2017, need to be carefully reviewed to avoid any confusion with the performance of claims made by manufacturers of aeration products. Ultra-OXYGEN found that most equipment INCORRECTLY refers to producing “fine bubbles” when it in fact only produces course and/or macro-bubbles that rise very quickly to the surface and do very little to leave any gas behind in the liquids like water.
