About submersible nanobubble mixer

The submersible ultrafine bubble mixing unit is a, complete submersible unit with the low-pressure mixing valve technique that effectively and efficiently saturates liquids with gases over 5 times the levels of conventional technologies. The UFB mixer produces fine bubbles that maximize water contact with the introduced gas producing a liquid highly saturated with suspended gas bubbles. With the UFB mixer, not only less gas is required to achieve optimum saturation levels, but once desired levels are achieved, the liquid maintains its saturation for extended periods of time. There is no need for pressurized tanks or high-pressure cylinders to keep the gases in solution.

The submersible unit consists of an UFB mixer combined with a pump, in a special Stainless-steel SUS 316L enclosing. The submersible unit can be equipped with a variety of pumps and two different sizes of UFB mixers, this makes the unit suitable for many applications:

  • Clean Tech – Chemical free cleaning solutions
  • Pond remediation
  • Agriculture and Horticulture
  • Aquaculture

The submersible unit features

  • Compact design, small footprint
  • Easy to connect and position in existing installations.
  • Efficient gas dissolution
  • Works in combination with a range of submersible pumps
  • Flexible systems design possible

Market application segments

The submersible ultrafine bubble mixer can be used for various applications, such as lake and pond remediation, treatment of agriculture and horticulture irrigation water, and aqua culture applications. Making the unit suitable for an application is done by varying the required pump in the unit.

Stainless steel 316L

The submersible unit is made from stainless steel 316L, in stainless steel there are 3 common qualities (property differences). The most common used is stainless steel SUS304 then 316 and 316L. Like 304, which is common in the food industry, both type 316 and 316L exhibit better corrosion resistance and are stronger at elevated temperatures. 316 stainless steel has more carbon in it than 316L. Both are very similar, durable, corrosion-resistant, and a good choice for high-stress situations. 316L is a better stainless steel for high-temperature, high-corrosion uses, which is why it's so popular for use in construction and marine projects and Acniti has chosen to use this quality to fabricate the submersible units from.

  • Marine applications
  • Architectural applications
  • Medical implants, including pins, screws and orthopedic implants like total hip and knee replacements
  • Fasteners


The unit comes standard with NBR seals also called Nitrile rubber. When the unit is used in seawater or an environment which is acidic or has oil contamination, we offer the possibility to upgrade the seals into fluoro rubber elastomers also called FPM, FKM, Viton. This seal is called according to DIN and ISO as FPM, as American Standard FKM. Viton® is the registered trademark of DuPont Performance Elastomers.

Oxygen concentrator

The use of an oxygen concentrator is recommended, air contains around 21% oxygen, by using an oxygen concentrator the oxygen level can be concentrated up to 90% – 95% making the pumping operation 4 to 5 times more efficient. The electricity usage is around 600 watts per hour. Supplying around 6 liters of oxygen per minute. This is more economic in electricity usage than using air.

Biology: agriculture, water-treatment

Often, we get the question can I also use the ultrafine bubble generator with air. While this is perfectly possible, from a chemical physical or technical point of view, by connecting a compressor to the installation. We recommended against the use of air from a biological point of view, in most cases we recommend the use of a single gas such as oxygen.

While with air, you will get around the same bubble concentration and bubble sizes as with oxygen. We have experienced that in a lot of cases dosing air, you also produce nitrogen and carbon dioxide bubbles. Especially CO2 is easy to dissolve, will lower your pH and can be used during daytime as a food source for algae production. Also, nitrogen bubbles don’t provide most of the time any benefit, it saturates the water with the wrong bubbles to create a healthy environment. For all these reasons, most of the time we recommend using pure O2.

Shipping, packing and installation

The submersible ultrafine bubble mixer, will be shipped by DHL or FedEx as a flat pack without a pump. This saves on transport cost. The preferred Tsurumi pump has to be bought locally, this has the advantage of local warranty and gives the security that the pump is safe to use on the local electricity network. Tsurumi has a worldwide strong network and their pumps are easy to buy online or via their dealers. Once you have received the submersible unit package, it's easy to mount with a star screwdriver and a 13 mm wrench. The package contains a bracket to sturdy mount the pump in the stainless-steel box.
