The phrase "aeration at the same" is not correct and does not make sense in written English.
It seems to be an incomplete expression and lacks context to determine its intended meaning.
Example: "The process requires aeration at the same time as mixing the ingredients."
Alternatives: "aeration simultaneously" or "aeration concurrently".
It was ascertained that an increase in the microbial concentration hinders the gas-liquid oxygen transfer rate in the boifilter due to the coalescence of air bubbles, while the oxygen transfer rate is considerably higher than that in the activated sludge aeration tank at the same gas flow rate.
Simulation results revealed that MBR's fitted with hollow fibres in a vertical orientation in the filtration zone experienced 25% more membrane surface shear than horizontally oriented fibres at the same aeration intensity.
In 5-L bioreactor, agitation speed was optimized at the same aeration rate (1.2 VVM).
By contrast, the changing body positions of the P-RM clearly restored lung aeration in the atelectatic areas at the same ventilator settings.
While the number of adventitious roots showed significant higher in NK57 than YD6 at the same aeration condition (Fig. 2C and Table 2A), and the surface area had no significant difference (Fig. 2D and Table 2B) between cultivars.
This could be seen in the form of enhancement factor as shown in Table 2. Enhancement factor can be defined as the ratio of k L a value in xanthan solution with palm oil, (k L a po to that of pure xanthan solution, (k L a) o both measured at the same aeration and agitation rate.
Moreover, it is interesting to find out that, for the standard sparger aeration to get the same kLa value at low or intermediate gassing rates, the power input can be greater than that for the surface aeration with the turbine placed very near the static liquid surface.
Using this model, the system performance was optimized by adjusting aeration and non-aeration time to control effluent ammonia level to preset values and at the same time to minimize energy consumption for aeration.
At the same total specific power input, aeration did not influence the mixing time much unless it changed the bulk flow pattern.
The aeration rate was adjusted from 1.2 to 0.6 VVM at the same agitation speed (130 rpm) in 50-L bioreactor.
