4.3.3. Scaling approaches to predicting full-scale performance from RSSCTs

Previous sections have alluded to constant diffusivity (CD) and proportional diffusivity (PD) approaches to designing RSSCT studies. Again, this refers to the assumptions we make about whether and how the diffusion coefficient of target pollutant molecules changes when adsorbent granules are crushed from the ~1 mm diameter particles used in full-sized t…
