7 (Release of a VOC from an open wastewater treatment basin) 2 Many volatile organic compounds (some of these are obnoxious and toxic) are formed in open wastewater treatment basins. Sadel et al. [Environ. Progr., 15 (1996) 82-92] studied the release of VOCs from an open basin in the wastewater treatment facility of Ciba-Geigy Corp. at McIntosh, Alabama. The liquid-phase mass transfer coefficient for methyl-isobutyl ketone (MIBK), a VOC, under a wind velocity of 3m/s over the basin was found to be kL=3cm/h and the gas-phase coefficient was kc=0.028m/s at 25C. If the Henry's law constant (pA=HxA) for MIBK is H=5.5atm, and its average concentration in the basin is 8.7ppm, calculate (a) the overall mass transfer coefficients, KL and KG; (b) the fraction of the total resistance offered by the gas-phase; and (c) the flux of MIBK if the bulk air is assumed to be free from the VOC
