air oxygen aerator for fish farming

1:Introduction:  

Porous ceramic diffusers are used for applications that require the production and dispersion of fine air or gas bubbles through the porous ceramic into a liquid. The finer the bubbles are,the more gas is exposed to the liquid which increases the gas transfer efficiency. The other important factor is that, when the bubbles are small, they rise significantly more slowly than large bubbles. As a result, there is more time for oxygen transfer, enhancing its efficiency . It is estimated that when the size of an oxygen bubble is smaller than 50 microns (0.05 mm), it will be completely absorbed in a 50% saturated water depth of 1 meter.   

Porous ceramic diffusers or spargers can also be designed into the system to cause

turbulence or mixing if desired.

The combination of the fine bubbles and low back pressure offers best Oxygen transfer efficiency in terms of energy consumption.

4:Applications:

Common uses for porous ceramic diffusers include:

• Aeration in municipal waste water plants;
• Diffusion for chemical reactions;
• Ozone diffusers for drinking water;
• Air/Oxygen diffusion for aquarium;
• Sparging in pharmaceutical process;
• Diffusion for aquaculture and hydroponics applications;
• Diffusing carbon dioxide (CO₂) either in pure form or diluted form in a bioreactor for producing algae and other forms of bio-fuels. The other similar application is to diffuse carbon dioxide (CO₂) into a liquid or chemical system in reduction or capture of carbon dioxide (CO2) emissions;
