Usually aeration of liquids is achieved by passing it through air or vice versa, by means of compressed air and diffuser(s) or air stone. Compressed air is used to refer to: Pneumatics, the use of pressurized gases to do work, as used in the Air car Breathing gas, often used in scuba diving, also to inflate buoyancy devices Compressed air can also be used for cooling using a vortex tube. ...

On a given volume of air or liquid the surface area changes proportionally with drop or bubble size, the very surface area where exchange can occur. Utilizing extremely small bubbles or drops, increases the rate of gas transfer (aeration) due to the higher contact surface area. This article explains the meaning of area as a Physical quantity. ...

Uses of aeration

• Production of aerated water for drinking purposes
• Secondary treatment of sewage or industrial wastewater with fine bubble diffusers,linear aeration tubing or coarse bubble diffusers
• To increase the oxygen content of water used to house animals, such as aquarium fish or fish farm
• To increase oxygen content of wort (unfermented beer) or must (unfermented wine) to allow yeast to propagate and begin fermentation
• To dispel other dissolved gases such as carbon dioxide or chlorine
• In chemistry, to oxidise a compound dissolved or suspended in water
• To induce mixing of a body of otherwise still water

Aeration (of soil) refers to the extent of air gaps in soil. See Porosity#Porosity of soil. Aeration commonly refers to the process of using mechanized equipment to either puncture the soil with spikes (spike aeration) or remove approxametely 1"X2" cores of soil from the ground (core aeration). Spike aeration involves the use of an aeration machine with spikes up to a foot or more in length. Spike aeration is sometimes used to address drainage issues in areas with turf. Core aeration is done on turf areas as a means of reducing turf compaction, reducing thatch buildup, improving the infiltration of water/nutrients, and creating an environment where grass seed can have direct contact with the soil. Bubbles in carbonated water float to the surface. ... Sewage is the liquid water produced by human society which typically contains washing water, laundry waste, faeces, urine and other liquid or semi-liquid wastes. ... Wastewater is any water that has been adversely affected in quality by anthropogenic influence. ... Fine bubble diffusers are a pollution control technology. ... Coarse bubble diffusers produce 1/4 to 1/2 inch bubbles which rise rapidly from the floor of a wastewater treatment plant or sewage treatment plant tank. ...
