Applying mass transfer models for controlling organic compounds in ozonation process

Application of Mass Transfer Models in Environmental Engineering

“…The gaseous ozone (O 3 ) will decompose to oxygen gas (O 2 ), as shown in Equation (2). In general, the decomposition rate increases as the temperature increases.…”

“…It is noted that the specific interfacial area is of great significance to the gas-liquid mass transfer. In ozonation process, the overall liquid-phase mass transfer coefficient (K L a) and equilibrium dissolved ozone concentration ([O 3 ] * ) can be obtained from the following mass balance equation [2]:…”

“…To determine the optimal operation conditions for semi-batch ozonation process, the "fractional ozone absorption (FOA)," defined as the ratio of the ozone transferred to water to the ozone applied to the reactor [7], should be applied. The FOA value in semi-batch operation can be expressed as [2] 3…”
