This paper presents the efficiency improvement in aerobic wastewater treatment technology
through the application of a microbubble generator (MBG) for aeration. Aeration using an
MBG is accomplished through water circulation and does not need air compressors, making it
more energy efficient than conventional aerators. The MBG aerobic system with the variations
on liquid flow rate (Q1) and airflow rate (Qg) combination was tested using artificial wastewater
with a typical composition of organic waste. Experimental data were evaluated by means of a
simplified mathematical model to systematically compare different MBG schemes. The study
confirmed that the soluble chemical oxygen demand (SCOD) removal efficiency was
significantly affected by the Qg values. Lower Qg values were preferable because they tended to
have higher soluble chemical oxygen demand (SCOD) removal efficiency. However, the
microbubbles were less stable at lower Qg due to the high incidence of bubble collisions. The
study concluded that for applications in an actual aerobic waste treatment pond, the positioning
of the MBG in the pond had to be carefully designed to minimize the collision tendency.
