Experimentally measure the sorption capacity of a GAC sample for methylene blue (MB) and apply this finding in the design of a GAC column.
Rate of inflow: 1x107 L/day (~2.6 MGD)
Inflow contaminant concentration: 0.5 mg/L
Equilibrium contaminant concentration: 0.0001 mg/L
GAC bed density: 750 kg carbon/m3
For a 2m diameter GAC column serviced annually, calculate the relationship between sorption capacity (range 0.1-1.0 g/g) and (1) column length, m and (2) annual operating cost of carbon replacement, 103$/yr.
