Bubbling & Sparging
The passage of a gas through a porous sintered material introduces bubbles in the liquid, an operation generically called sparging. This process can be used in beverages, such as carbonation, or even packaging, to increase the shelf life of the product. The animation shows the working principle of the bubbling process (sparging). Gas is injected through the lower part of the sintered porous element (stainless steel), and bubbles are generated in the upper part. The introduction of air or oxygen into culture media (fermentation) makes use of this process.
In bubbling, or sparging, a gas is injected into a liquid, through the porous element. The generation of bubbles generates turbulence or transfers gas to the liquid. Used in beverage carbonation, in fermentation processes and in flotation operations.

Porous components for bubbling
In the photo we can see different geometries of porous components that are used in the injection of gas into a liquid medium (sparging or bubbling). The size of the generatedbbubbles is related to the porosity of the component (pore size and distribution). -
Porous components for gasification
We can see here a porous component that is introduced into the central part of the T, through which gas can be injected. When the liquid passes through this T, it carries with it a large amount of small gas bubbles, which are incorporated into the drink, improving the shelf life of the product. -
Porous Components for Laboratories
These types of devices are used in aeration tanks to promote the transfer of gases to liquids, typically in applications such as water treatment, chemical reactions, or oxygenation. This element distributes the gas throughout small bubbles, increasing the contact area and, consequently, mixing (or oxygenation) efficiency, and can be used, for example, in culture media.
