Abstract

Granular activated carbon (GAC) performance in removing MTBE in the presence of competitors, e.g., natural organic matter, volatile organics present in gasoline (BTX), and breakdown products of MTBE (tributyl alcohol), was studied. The resulting rapid small-scale column test (RSSCT) testing matrix simulated a range of MTBE concentrations with varying empty bed contact times (EBCT) and background NOM. For ground water from Santa Monica, CA, (Arcadia Well Water) the breakthrough curve for the 20 min EBCT was more S-shaped, whereas the breakthrough curve for the 10 min EBCT was more spread out, suggesting slightly better equilibration between coconut GAC and MTBE at 20 min EBCT. The 10 min EBCT was sufficient for MTBE to reach equilibrium and was recommended for pilot plant studies at Santa Monica and Lake Tahoe groundwaters.
