The phrase "aerated bed" is correct and usable in written English.
It can be used in contexts related to engineering, environmental science, or agriculture, particularly when discussing systems that involve air circulation through a medium.
Example: "The wastewater treatment facility utilizes an aerated bed to enhance the breakdown of organic matter."
Alternatives: "aeration system" or "air-infused bed".
Results demonstrated enhanced nitrification in the aerated bed with 99% mass removal up to the maximum tested loading rate of 10.1 gNH4+-N/m2/d.
Alternatively, vibration of the gas distributor of the aerated bed at best results in channel elimination in the lower part of the bed only.
By simultaneously applying both vibration and stirring of the aerated bed, it is possible to eliminate both channelling and starch agglomeration.
For a potato starch bed of 0.76 m initial height and 0.288 m diameter with a moisture content W = 13.1 weight% dry basis, channel formation can be suppressed only if the aerated bed is effectively stirred.
Five cohesive solids have been aerated in beds activated by an acoustic field of 150 dB and 120 Hz.
The conveying system consists of a blow vessel with three points of gas injection to aerate the bed of material and facilitate hopper discharge.
A full scale comparison of a newly commissioned artificially aerated horizontal subsurface flow constructed wetland and a non-aerated bed of identical design was conducted to determine the efficacy of artificial aeration on tertiary nitrification.
In comparison, an ammonia removal of 59% was observed in the non-aerated bed up to a loading rate of 1.6 gNH4+-N/m2/d beyond which performance deteriorated.
An aerated gravel-packed contact bed (CB) system was built in 2011 and part of the stream water was treated by the CB before discharging to the CW.
The mass flux of each material was studied as the system parameters were varied, which included: fluidizing and sparge gas (two of the three gases aerating the hopper bed), transfer gas (gas injected directly into the solid transfer line), pressure drop, conveying gas type and transfer line diameter.
Columns were aerated at one, two, and three levels of the bed depth, with air introduced at flow rates calculated from methane oxidation reaction stoichiometry.
