Simultaneous transport and transformation. A stream of ozone-enriched air ( 3% ozone by volume) is bubbled into a reactor as part of a disinfection strategy. Water entering the reactor is free of ozone. KH=0.011M/atm and KLa=18h1 for ozone in this system. Ozone (O3) dissolved in water is unstable. The kinetics of decomposition are complex, but the rate can be approximated as first-order with respect to dissolved ozone. The first-order rate coefficient is pH-dependent and, at pH 8.0 and 25C, is 12h1 in the system of interest. Find the steady-state concentration (mg/L) of dissolved ozone in the effluent if the reactor is operated as a CMFR with a 15min retention time
