batch versus column

[Flynn]

Hi all,
I would really appreciate some light on the following matter:
Pendelton et al. 1997, correlated increased oxygen content with increased hydrophilicity in an activated carbon. They then correlated this with lower removal of a taste and odor component they were removing. Now this was done in a batch test. I have not been able to extrapolate this finding to column studies to agree or disagree. Could you think of any reason/s that the oxygen content of an activated carbon would or would not have the same impact on its performance in batch and column situations ?

The only difference is that in a batch process there is a correlation between the concentration and the load on the carbon, i.e., the load on the carbon is controlled by the concentration in the fluid, usually called isotherms. These isotherms are for a range of concentrations. Column performance is usually explained by breakthrough curves. I have never been able to apply isotherms to columns except for estimating carbon usage and cost. But maybe someone else has.
