The wаstewаter is tо treаted by a fixed-bed granular carbоn adsоrption column. The flow rate of the City of Orlando treatment facility flow rate is 60,000 gpd and the allowable breakthrough concentration, Ca is 20 mg/L. The design column has a unit liquid flowrate of 5 gpm/ft2 and the on-line time is eight (8) days. Your firm has been asked to use the “Kinetic” approach in your design using the following information. Q = 60,000 gpd C0 = 450 mg/L Ca = 20 mg/L Qunit = 5 gpm/ft2 On-line time (t) = 8 days Rate constant (k1) = 55.38 gal/lb
