Q. Will nanobubbles affect my optical DO sensor accuracy?
A. The optical path does not go through water, and so the system is not sensitive to bubbles in water.

Q. Will the optical DO micro-sensor be able to read saturation with nanobubbles?
A. If the bubbles are present in significant numbers in the fluid around the sensing element, and if there is an appreciable exchange between the bubble of that particular size range and the fluid, the presence of the bubble should manifest in the dissolved oxygen signal.

Q. Do nanobubbles help with scale inhibition?
A. Studies show that CO2 nanobubbles can mitigate scale formation. There are studies that demonstrate CO2 nanobubbles and air nanobubbles mitigate scale formation; however, scaling is highly depending on the mineral and the surface. Consult a Moleaer representative to better determine if nanobubbles can help.

Q. What type of water or liquid can I pump through your nanobubble generator?
A. Moleaer systems are designed around specific flow rates, not type of liquid. Moleaer systems are liquid agnostic but are designed for specific flow rates. Please contact a Moleaer representative with help selecting the correct equipment based on the type of liquid you are looking to treat or enhance with nanobubbles.

Q. Do I need to pre-treat the water?
A. Pre-treatment is not required in most cases. Pre treatment is not required, however in certain cases, filtering out larger solids is beneficial. Equipment performance is dependent on the concentration and size of solids.

Q. Can I use any gas with the nanobubble generator?
A. Following local safety restrictions most gases are injectable. Moleaer nanobubble generators can inject most gases. However, local safety restrictions must be taken into account on a case by case basis to avoid any hazardous situations.

Q. What is the correct gas flow?
A. Varies by product and installation. Gas flow is measured by the rotameter and varies by product and installation.

Q. What is the recommended gas pressure (range)?
A. Generally 40-100 psig. Recommended gas pressure is generally 40-100 psig, but varies depending on customer needs.

Q. How many pounds per day of oxygen does each system transfer into clean water?  Process Water?
A. Mass transfer varies by product and installation. Mass transfer is dependent on gas type, altitude, temperature, gas pressure and liquid source/flow rate. A Moleaer representative can help assist you with determining the anticipated mass transfer depending on your circumstances.

Q. What type of air filtration is required for the compressed air?
A. Mass transfer varies by product and installation. Mass transfer is dependent on gas type, altitude, temperature, gas pressure and liquid source/flow rate. A Moleaer representative can help assist you with determining the anticipated mass transfer depending on your circumstances.

A. By 2021 all products will have remote monitoring. Yes. A number of Moleaer products include remote monitoring capability and starting in 2021, all products will have this feature.

Q. What is the required maintenance of a Moleaer nanobubble generator?
A. Maintenance varies by model and application. Maintenance needs vary by model, but in general they are very simple to maintain. Depending on the application, Moleaer recommends standard preventive maintenance on the pump and compressor (when included), then monitoring the flow and pressure to determine when cleaning is necessary.

Q. How do we deal with moisture inside the CFH rotameter?
A. Moisture accumulation is normal and, if needed, can be extracted with a cotton swab. Moisture accumulation is normal when feeding our units with compressed air. When the unit is off, you can undo the nut on the top of the rotameter and use a cotton swab to extract the moisture. Additionally, if you have moisture in the air lines you can disconnect the air line at the block and let the compressor blow the excess moisture out. Lastly, make sure to drain the compressor tank periodically if it does not have an auto drain on it, this will help reduce the amount of moisture build up over time.

Q. Should the compressor cycle on and off or run continuously?
A. Compressors should not be started more than 6 times an hour. Continuous cycling of the compressor will cause it to wear faster because at shutdown the head continues to heat up and can cause failure. Meanwhile running the compressor in a continuous manner allows for constant cooling by the fan. This is a known issue with compressors and why it is recommended that you start no more than 6 times an hour

Q. Do I need to replace the nanobubble generator over time? If so, how often?
A. Nanobubble generator wear varies by use, application, and environmental conditions.

The nanobubble generator performance can wear over time; however, this varies significantly by use, application, and environmental conditions. A more precise answer can be provided on a case by case basis and then, if needed, the nanobubble generator is simple to replace.

Nanobubble Fundamentals

Learn more about nanobubbles and what makes them unique

Q. What is a nanobubble?
A. Nanobubbles are nano-sized bubbles, 2500x smaller than a grain of salt, that help industries use less water, chemicals and energy by changing the properties of water.

Q. How do nanobubbles improve flotation if they themselves do not float?

A. Many nanobubbles acting together can float larger particulates. Due to the natural surface charge of a nanobubble, many nanobubbles will attach themselves to individual particulates in the water, and when once enough act together it will result in that particulate floating even though individual nanobubbles themselves do not. We are happy to provide research papers that speak to this concept.

Q. Will nanobubbles remain entrained in the water after the treatment process?
A. The less biologically active the environment, the longer nanobubbles remain present. Nanobubble longevity is dependent on the dissolved gas demand in the treatment process. In clean water applications the bubbles will last days to weeks as the dissolved gas concentrations increase. For biologically active or other high demand environments, bubble existence is much shorter due to the high demand in the liquid for the dissolved gas.

Q. Do you have white papers or independent studies?
A. White papers and independent studies are available upon request. Yes. Moleaer works with nearly a dozen University or research labs to study the benefits of Moleaer nanobubbles on all commercial applications. Please contact a Moleaer representative to discuss the specifics of these research projects.

Q. Do nanobubbles change the viscosity or density of the liquid they are injected into?
A. Based on independent testing, the viscosity is changed with an increased concentration of nanobubbles.

Q. Do I need a permit to install a Moleaer unit?

A. A permit is typically not required, check with your local agencies. You do not typically need a permit to install a Moleaer nanobubble system. Moleaer's systems are an EPA registered pesticide "device" (which does not require a permit like pesticide "chemicals". Some jurisdictions do however require permitting or approval to install aeration or other devices in surface waterbodies such as fountains, aerators, circulators or nanobubble generators.

Q. How far do you need to run piping?
A. Piping installation guidelines vary based on model. Piping guides are provided with all Moleaer nanobubble systems and can be found in the installation guide. It is best to use shorter lengths of pipes whenever possible to increase the pump efficiency of a nanobubble generator.

Q. How loud are the units?
A. Noise rating depends on the specific model. Specific decibel ratings for each unit can be found by contacting a Moleaer representative. The Clear unit family is rated for <65 dB. This is equivalent to a normal conversation between two people. If you were standing next to a Clear unit, you would not need to raise your voice to be heard.

Q. What is the lifetime/warranty?
A. All Moleaer systems have a 1-year warranty for workmanship and materials included. Extended warranties and remote monitoring services are available. Please contact a Moleaer representative for more information.

Q. How do I prepare a unit for the winter season?
A. Moleaer units must be winterized when and where appropriate. Moleaer units can be winterized upon delivery, if requested at the time of order. Otherwise, it is important to winterize it each year by shutting the system off and draining the system and all piping, or by taking it off-site.

Q. Can you treat a targeted/small area, i.e. swimming beach on large lake?
A. Moleaer has successfully treated targeted areas. Yes.  Moleaer has successfully treated targeted areas on larger water bodies. Careful consideration must be taken on where the unit is installed; specifically taking into account currents and the location of the intake & discharge.

Q. Will nanobubbles harm zooplankton?
A. Nanobubbles have no known impact on zooplankton. There is no evidence that Nanobubbles have an impact on zooplankton. Moleaer recognizes the importance of maintaining a healthy food-chain for the ecosystem of your water body.

Q. Will nanobubbles affect pH?

A. Nanobubbles do not directly affect pH levels. However, as algae problems are mitigated then pH will likely decrease.

Q. Will nanobubbles disrupt thermal stratification?
A. Potentially, nanobubbles themselves are nonbuoyant and do not float or cause lift like traditional aeration systems, however, mechanical mixing forces through the pumping of water and the excess gas that is discharged will disrupt stratification. Thoughtfully designed intake and discharge lines can reduce the impact to stratification.

Q. Can nanobubbles move through a thermocline?
A. It is unlikely that nanobubbles will break through a thermocline due to the density changes in water.

Q. Does the nanobubble system work with other conventional pond aeration systems?
A. Yes, using other aeration and mixing devices such as fountains, bottom diffusers and circulators has no negative impact on the use of nanobubbles.
