Aeration or aerification is the process by which air is circulated through, mixed with or dissolved in a liquid or substance.
Aeration of liquids is achieved by:
- passing the liquid through air by means of fountains, cascades, paddle-wheels, cones or nozzles.
- passing air through the liquid by means of the Venturi tube, aeration turbines or compressed air which can be combined with diffuser(s) air stone(s), as well as fine bubble diffusers, coarse bubble diffusers or linear aeration tubing.
Ceramics are suitable for this purpose, often involving dispersion of fine air or gas bubbles through the porous ceramic into a liquid. The smaller the bubbles, the more gas is exposed to the liquid increasing the gas transfer efficiency. Diffusers or spargers can also be designed into the system to cause turbulence or mixing if desired.
