FAQs- Nanobubble Technology

Q 1. What is Nanobubble Technology?

It is a technology developed by applying the shear resistance relationship between the interface of the object and the adjacent area. When gas(ex. oxygen) is split into nanosize by the shear force generated at the interface of the object, dissolved gas is increased. Nano-sized bubble(gas) exists in water for a long time without degassing, and dissolved gas is maintained high for a long time.

Q 2. What are the various application fields of Nanobubble technology?

Nanobubble Technology is applicable in various fields where water purification and the use of purified water is a requirement. Thus, it can be used in cleaning pond waters, lake waters, producing oxygen-enriched drinking waters, in poultry and cattle farms, in agriculture, aquaculture, etc.

Q 3. How long nano bubble can stay in the water?

It can stay up to 30days

Q 4. Is traditional or nanobubble aeration a better solution for HAB control?

Thanks to the oxidation effect they provide, nanobubbles are a superior solution for the reduction of Harmful Algae Blooms (HABs) and the toxins they can produce. Nanobubble technology also helps create a better environment for beneficial bacteria to thrive, which helps compete with an excess nutrient load, ultimately reducing the likelihood of algae and aquatic weed growth.

Q 5. Are nanobubbles more effective in larger or smaller waterbodies?
Nanobubble aeration has proved to be extremely useful on smaller waterbodies that are less than 5 acres. At this point, more testing is needed to determine if larger waterbodies would experience the same benefits. We believe larger waterbodies, over 20 acres, could be positively impacted by this technology, but multiple units would be needed to ensure proper distribution.

Q 6. How long does a nanobubble “treatment” last?
Every pond differs in its physico-chemical characteristics, which, in turn, determine how long the nanobubble treatment might last. Nanobubbles themselves have been observed to last 2-3 months or more, but many factors can affect that time. For example, the greater the biological oxygen demand on the pond, the shorter the bubbles will last because they will be working hard to oxidize the pollutants. The longer you run a nanobubble unit, the longer the results will last. Ponds with better water quality will have longer-lasting nanobubbles than "dirty" ponds. Likewise, the presence of other water features that mix or move the water can cause the nanobubbles to have a shorter life. For example, fountains or architectural waterfalls can cause nanobubbles to implode prematurely. That's not to say you can't use a fountain and nanobubble technology simultaneously; if your nanobubble unit is running consistently, the number of bubbles produced can offset the destruction of bubbles by sheer numbers.

Q 7. How many hours per day does a nanobubble system need to run?
We are still learning what kind of approach works best when it comes to the operation of nanobubble systems. However, we do believe that once an entire waterbody is saturated with oxygen, there is a possibility that system operation could be reduced to just a portion of the day. The long lifespan of a nanobubble should allow for intermittent operation without negatively impacting the long-term benefits.

Q 8. Will nanobubbles help increase oxygenation in a water body that is continuously replaced with anoxic well water?
We believe the answer to this should be determined by how much of the lake is turned over every day. Nanobubble technology will increase oxygenation, especially if the system is set up near the area where the well enters the lake. As long as the flow is not too fast for the nanobubbles to keep up with, there should still be positive benefits.

Q 9. How much noise does the machine make and what is the size?
Noise levels depend on the size of the unit. There have been some complaints about the noise created by larger units; however, improvements have been made to minimize many of those issues successfully. Recent data for our standard nanobubble systems shows that the noise levels are less than what you would hear from your air conditioning unit or pool filter. Landscaping around your nanobubble unit can also help cancel out some of the noise.

Q 10. Can nanobubbles be used to help with iron and manganese problems in large reservoirs?
Additional testing would be required before we could sufficiently answer this question. Nevertheless, just as bottom diffused aeration can help with iron issues, there is every reason to believe that nanobubbles would have the same effect. It is possible that by distributing nanobubbles evenly throughout the water column, aeration may be even more effective for iron.

Q 11. Do all nanobubble machines use ozone, and what does that provide that oxygen does not? Also, does ozone have any negative effect on fish or wildlife?

We are still learning about the effects of ozone on the environment, and more studies need to be completed before we will be comfortable with its widespread use.

Q 12. Is nanobubble aeration cost-effective? How does cost compare to traditional aeration or treating your waterbody with herbicides or algaecides?
Nanobubble generators are relatively expensive for each unit compared to traditional aeration. Nonetheless, nanobubble experts believe the technology is cost-effective over the long term, which is why KBK Group offers it as service on a monthly basis. Nanobubbles provide many more benefits and results compared to traditional aeration and, in many cases, may serve as a replacement for conventional algaecides.

Registered algaecide treatments are environmentally safe and can work very well when applied by a licensed professional; however, we have found that once an eco-friendly nanobubble unit is established, it usually eliminates or reduces the need for algaecide treatments.
