An experimental study to examine the capabilities of the microbubble generator (MBG) on
aerobic wastewater treatment was carried out under laboratory and industrial conditions. The
tested MBG types were porous pipe & orifice and an MBG with a spherical body and drilled
holes. In the laboratory-testing condition, an MBG was placed at a depth of 40 cm from the
water surface. Three different pressure transducers were installed around the body of the MBG
in order to analyze the inlet water pressure, the air-suction pressure, and the pressure at the
outlet of the MBG. Next, the bubble diameter was measured by capturing the bubble pictures
using a digital camera and analyzed using a developed image-processing technique. In order to
simulate the application of the microbubble generator in the industrial field, a feasibility test of
the MBG in aerobic wastewater treatment was performed. The results show the increase in
MBG quantity with a higher ability to increase the oxygen, and that it is necessary to arrange
the placement of each MBG in configuration to minimize bubble coalescence. Furthermore, by
using a bio-ball as the porous media for microorganism attachment in aerobic wastewater
treatment, the feasibility test showed promising results. Carbon on demand (COD) could be
reduced to around 354 mg/l. The value of dissolved Oxygen (DO) was larger than 2 mg/L. The
Ph level remained at 6, and temperature remained no more than 35ÂșC, which meet the
requirements of aerobic wastewater treatment.
