Based on the results of over twenty laboratory granular activated carbon (GAC) columnruns, models were developed and utilized for the prediction of 2-methylisoborneol (MIB)breakthrough behavior at parts per trillion levels and verified with pilot-scale data. Theinfluent MIB concentration was found not to impact the concentration normalizedbreakthrough. Increasing influent background dissolved organic matter (DOM) concentrationwas found to systematically decrease the GAC adsorption capacity for MIB. A series ofempirical models were developed that related the throughput in bed volumes for a range ofMIB breakthrough targets to the influent DOM concentration. The proportional diffusivity(PD) designed rapid small-scale column test (RSSCT) could be directly used to scale-up MIBbreakthrough performance below 15% breakthrough. The empirical model to predict thethroughput to 50% breakthrough based on the influent DOM concentration served as inputto the pore diffusion model (PDM) and well-predicted the MIB breakthrough performancebelow a 50% breakthrough. The PDM predictions of throughput to 10% breakthrough wellsimulated the PD-RSSCT and pilot-scale 10% MIB breakthrough. |
