Question
Calculate the specific throughput for two GAC beds in series with the first bed having a 10min EBCT and the second bed a 22min EBCT.
Calculate the specific throughput for two GAC beds in series with the first bed having a 10min EBCT and the second bed a 22min EBCT. The GAC density F is 0.457 g/mL. The average DCE influent concentration is 80 g/L. The treatment objective is 5 g/L. The DCE concentration is zero for the column with EBCT of 32 min before 200 d. The DCE concentration is zero for the column with an EBCT of 10 min before 50 d. For two beds in series, the treatment objective from the second column is exceeded after 290 days. The effluent from the first bed is 64 g/L when the treatment objective from the second column is exceeded.
