    As stricter environmental regulation have led to an increase in the water treatment cost, it is necessary to
    quantitatively study the input power of the aeration process to improve the energy efficiency of the water treatment
    processes. The objective of this study is to propose the empirical correlations for the mass transfer coefficient with the
    gas hold-up and input power in order to investigate the mass transfer characteristics of the aeration process. It was
    found that as the input power increases, the mass transfer coefficient increases because of the decrease of gas hold-up
    and increase of Reynolds number, the penetration length, and dispersion of mixed flow. The correlations for the
    volumetric mass transfer coefficients with gas hold-up and input power were consistent with the experimental data,
    with the maximum deviation less than approximately ±10.0%.
