The phrase "aeration unit" is correct and usable in written English.
It can be used in contexts related to environmental science, agriculture, or engineering, particularly when discussing systems that introduce air into a substance, such as water or soil.
Example: "The aeration unit is essential for maintaining the health of the fish in the aquaculture system."
Alternatives: "air injection system" or "oxygenation device".
The biomass is suspended and aerated in the water of the aeration unit(s) by either submerged air flow or mechanical agitation.
The mixed liquor volatile suspended solids (biomass) is greater than 1 kilogram per cubic meter throughout each aeration unit.
A thoroughly mixed treatment unit is a unit that is designed and operated to approach or achieve uniform biomass distribution and organic compound concentration throughout the aeration unit by quickly dispersing the recycled biomass and the wastewater entering the unit.
An aeration unit in an Aerated Submerged Biofilm Wastewater Treatment Process (ASBWTP) was picked up to support the derivation of a solid fuzzy control rule base.
Enhanced biological treatment system or enhanced biological treatment process means an aerated, thoroughly mixed treatment unit(s) that contains biomass suspended in water followed by a clarifier that removes biomass from the treated water and recycles recovered biomass to the aeration unit.
When 500 l d−1 wastewater had been pre-treated in an intensive aeration unit BOD5 removals of the order 98.6% occurred in the aeration plant, 75.1% in the reed bed and 99.6% in the whole system incorporating the reed bed.
Passive aeration units are units that operate without the need for electric energy.
Furthermore, we present evidence that turbulence generated by aeration units and fish-feeding activity also induces particle breakdown.
Open image in new window Fig. 3 Wind distribution during artificial aeration, the unit of wind speed is m s−1.
Still, no three-dimensional model has been presented for hypolimnetic aeration with units that pump epilimnetic oxygen-rich water through the thermocline to the hypolimnion without breaking the thermal stratification.
According to experimental [ 4, 12, 13] and human [ 14, 15] studies, re-aeration of a non-aerated lung unit depends not only on the inflating pressure, but also on the duration of sustained pressure, the so-called inflating pressure-time product (pressure × time) [ 16].
