Nano Bubble systems applications Aquaculture add Nan02!
Neutral Buoyancy
Nano bubbles have a typical mean diameter of roughly 80nm based on extensive testing through independent laboratories using Malvern's Nano Sight Nanoparticle Tracking Analysis software. Bubbles this size lack enough buoyancy to reach the surface and instead follow Brownian motion. The net effect is that nano bubbles will remain suspended in water for months until they dissolve, traveling randomly throughout the body of water and efficiently aerating the entire water column. Subsequently, dissolved oxygen (DO) measured at the deepest parts of a tank or pond will match the DO recorded near the surface. This unique behaviour enables nano bubbles to provide a homogenous distribution of oxygen throughout an entire body of water. All bubbles naturally possess a surface charge. The smaller the bubble, the stronger the surfaces charge. Nano bubbles have a high zeta potential, which is the electro kinetic potential in colloidal dispersions. Through the testing done with zeta-sizers, it has been shown that the strong negative charge of nano bubbles limits their coalescence, meaning the integrity of the bubble is preserved at any depth for extended periods of time. Additionally, the negative charge combined with their high concentration improves separation efficiency in flotation processes by increasing collision probability. This unique property allows wastewater, Oil and Gas and Mining operators to float more suspended matter than through conventional methods
Oxygen Reserve
The neutral buoyancy and negative surface charge of nano bubbles allows them to remain in suspension for months at a time. This occurs even after the solution reaches oxygen saturation. In this capacity, the nano bubbles act as a gas reserve in the solution. As oxygen is consumed from the water by biology, chemistry, or off-gassing, the nano bubbles rapidly diffuse more oxygen into the water, maintaining elevated dissolved oxygen levels until the nano bubbles are depleted. This additional gas reserve, estimated up to 20% over the saturation point, enables industries to utilize gases more cost effectively than ever before.
Aquaculture
Over half of the fish and shellfish directly consumed by humans are produced through aquaculture, also known as fish farming. As fish farmers look to produce more fish to keep up with global demand, they run into severe problems with a lack of dissolved oxygen (DO) in the water. Fish and shellfish need oxygen to breathe. When fish populations are tightly packed, a shortage of DO is inevitable because the fish and shellfish consume more oxygen from the water. Additionally, waste by-product accumulates on the floor of the fish farm, damaging or eliminating bottom-dwelling plants and animals. Moleaer's advanced gas-to-liquid injection technology can alleviate these problems by rapidly elevating and maintaining higher levels of DO levels in the fish farm and effectively oxygenating sea floors due to the nano bubbles lack of buoyancy. Total weight of sweet fish increased from 3.0 to 6.4 kg in normal water, whereas it increased from
3.0 to 10.2 kg in air-nano bubble water. In addition, total weight of rainbow trout increased from 50.0 to 129.5 kg in normal water, whereas it increased from 50.0 to 148.0 kg in air-nano bubble water. Free oral intake of oxygen-nano bubble water significantly promoted the weight and size compared to that of normal water. We have demonstrated for the first time that oxygen and air-nano bubble water may be potentially effective tools for the growth of lives.
Stocking Density
The metabolic rates of fish can be severely affected by the concentration of oxygen in the farm. Low DO levels lead to decreased respiration and feeding activity that slow fish growth rates. An oxygen saturation level of 85% and above is ideal for aquaculture; lower levels have varying effects on the fish and molluscs, ranging from reduced appetite to massive mortality rates. Oxygen aeration using the Moleaer’s nano bubble generator ensures that fish farmers can achieve the highest possible stocking densities while ensuring high survival rates to boost yields and profits.
Disease Prevention
Low DO levels in the water of an aquaculture farm can also lead to disease and fungal infections. A lack of DO can lead to a build-up of fish and mollusc waste on the sea floor, creating conditions that are ideal for bacteria and fungus to thrive. Farmers have traditionally turned to vaccination, antibiotics, or additive chemicals to deal with these issues. However, these methods are costly and cause great stress to the fish, making them less healthy for human consumption. Moleaer's nano bubble technology uses the power of clean and natural oxygen delivered through neutrally buoyant nano bubbles to prevent disease, providing a much healthier, efficient, and cost-effective solution for aquaculture.
Efficient Oxygen Transfer
Aquaculture farmers need large amounts of oxygen to maintain a healthy fish and mollusc population. Failure to add any additional oxygen to the water will lead to poor growing conditions
and is not a feasible option. Traditional aeration methods are very inefficient, leading to high costs to achieve proper DO levels. Dry Tech Aerogels nano bubbles, Nan02 is the ideal technology to maximize oxygen utilization for the aquaculture industry by delivering the highest oxygen-transfer efficiency, over 90%, of any aeration method on the market today.
Dosage
Add 30mg/liter water, depending on stock density, DO levels need to be taken once or twice per week.
