TECHNOLOGY

The ability of a water body to take, dissolve and keep the gases dissolved in the water is primarily driven by four factors i.e. pressure, temperature, gas liquid contact surface area, and solubility. The maximum gas a water body can hold, naturally driven by these four factors, is what is known as the “Saturation” point of that gas in water. Once water or liquid achieves or nears saturation it starts releasing the gases back to the atmosphere and its solubility decreases therefore most Aeration systems find it more and more difficult to dissolve Air/Oxygen as the levels increase towards saturation Point. As these factors are not uniform across the planet, the saturation point of any gas is different in different areas of the world. The Nanobubble Technology is the only Aeration technology of its kind which can, not just, Saturate water with Air/Oxygen/Gas easily but in fact achieve Super Saturation.

Over the years mankind has understood and devised various applications which seek to increase or decrease the gases in the water for various uses and productivity. The most sought after or rather the ‘HOLY GRAIL’ of Aeration or any gas mixing is the achievement of maximum dissolution of gas with least amount of energy. Over the years, most technologies involved, in the dissolution/ aeration/mixing of gas or air, focused on the transfer, insertion or mixing efficiency of their equipment with respect to energy or power. In other words, they focused on inserting gas or mixing it into the water using the least amount of energy. However, what is important rather than just inserting or mixing is the amount of gas actually dissolved in water or liquid. For example, when we add sugar to our tea and sugar remains undissolved irrespective of the amount of sugar put. Another example would be trying to fill a glass of water by flinging water from a huge bucket towards it. (A surface aerator or fountain throws water in the air expecting oxygen to get dissolved in the water). In other words, a huge transfer or insertion to compensate for the inefficiency to dissolve leads to power wastage and inability to achieve the complete objective. Since gas dissolution is a function of temperature, solubility, and pressure all put together and found variable, it is important for any GAS dissolution system or Aeration system to focus on all these factors and not solely on the transfer or mixing. Gas transfer occurs at the bubble-water interface, It is widely accepted that maximum transfer of gas is achieved when it is discharged or diffused in the form of the smallest size of bubbles i.e. smaller the size of the gas bubble in the water, higher the transfer efficiency. This is due to the greater surface area achieved by packing trillions of small bubbles in unit space.

The ACS GDS nanobubble technology is the only system of its kind which seeks to achieve results by combining the process of efficient insertion, efficient mixing, right pressure and high transfer to boast of gas dissolution or Gas dissolving rates of more than 95%. Above all the extremely slow rise and stability of the bubbles help achieve levels of dissolved gasses not just towards saturation but supersaturation (above saturation levels). The ability to achieve such high rates of dissolution at such fast rates allows the technology to be implemented and used across various applications. The ACS GDS technology dissolves gases in a highly concentrated fluidic liquid by inserting it efficiently using venturis and employing a multi-stage process using a proprietary design of impeller and disc structures rotated at a very high RPM which helps in mixing the gas and liquid under high pressure. The gas is then divided into extremely fine bubbles and then discharged or diffused in the water, body to achieve more than 95% gas dissolution efficiency. We use a fully contained unit with inlet, outlet, pumping and mixing that is easy to customize depending on application and situation. Because of this revolutionary gas dissolving ability it now becomes possible and economically feasible to dissolve various gases (like air, oxygen, ozone, nitrogen, carbon dioxide, etc.) in pure form without losing them to off gassing. For example, ozone can be dissolved without the need for off gassing capture and destroy equipment’s and oxygen /ozone generation requirements become more operationally and economically feasible.

For a complete dissolution of gas in a liquid or water body, it is important that all the gas that is inserted or mixed is transferred in a highly efficient manner. This means that bubble sizes need to be extremely small and in a large quantity or ratio. The ACS GDS generates gas bubbles which are less than 5 micron and more than 85-90% of them. These bubbles due to high pressure break up into extremely small nanobubbles once discharged.

This helps to saturate or supersaturate the water body with the inserted gases like oxygen or ozone and remaining stable for hours on end. However this is not all, these Nanobubbles have some other qualities too which are:

The breakup of the bubbles discharged from our system into the water releases a high amount of energy and free radicals which also acts as a catalyst for major applications for water disinfection and treatment using ozone or oxygen.

a) The implosions result in the nanobubbles attaining negative charge thus repelling each other which means larger area coverage. b) They also attract the positively charged contaminants and help bring them to the surface achieving Suspended Solids liquid separation like never before.

The utility of these qualities helps it to hugely distinguish itself from not being just an aeration or gas dissolution device but a dissolved gas floatation/separation system too. In fact, the ability of nanobubbles to saturate liquids with AIR bubbles and hence separate oils is well researched and documented. This renders the ACS GDS as the only system of its kind which helps dissolve gas, separate or remove TSS achieve water clarity and cover large areas of application all at the same time.
