True or False: The theory behind shallow aeration is that the oxygen transfer efficiency during bubble formation is several times higher than that during bubble rise; therefore, when the oxygen transfer rate is the same, shallow aeration requires less electrical energy. ( )
The theory behind shallow aeration is that the oxygen transfer efficiency during bubble formation is several times higher than that during bubble rise; therefore, when the oxygen transfer rate is the same, shallow aeration requires less electrical power. (True)
