TY - JOUR N2 - Dissolved oxygen is one of the leading indicators of aquatic quality. This study explored a membrane-based bubble generator (MBG) for oxygen dissolution in water. It is achieved by creating negative pressures to suck the air through a thin, porous film and forming bubbles in liquid water. Both airflow and liquid flow rates played essential roles in forming the bubbles. The highest oxygen dissolution energy efficiency of 1.48 kgO2/kWh was achieved under free-flowing air at corresponding air and liquid velocities of 4.87 L/min and 2.46 m/s, respectively. The obtained oxygen dissolution energy efficiencies were comparable with established commercial oxygenators. The results revealed a promising application of porous membranes in MBG as a potential energy-efficient oxygen dissolution technology. © 2022 N1 - cited By 5 KW - Dissolution; Energy efficiency; Energy utilization; Liquids; Potential energy KW - Bubble generators; Bubble-in-liquid; Dissolution energy; Leading indicators; Membrane-based; Microbubbles; Negative pressures; Oxygen dissolution; Porous film; Specific energy consumption KW - Dissolved oxygen ID - scholars16792 TI - A novel membrane-based bubble generator for oxygen dissolution in water AV - none UR - https://www.scopus.com/inward/record.uri?eid=2-s2.0-85128692882&doi=10.1016%2fj.cep.2022.108938&partnerID=40&md5=4a81bb02a71f824b0dce7cb6e25606a3 JF - Chemical Engineering and Processing - Process Intensification A1 - Mohd Rasdi, W.N.A.
