Performance of a Submerged Adsorption Column Compared with Conventional Fixed-bed Adsorption

Submerged adsorption (SA) process has been explored in this context for the first time as a dynamic and effective approach, comparable to the conventional fixed-bed adsorption. Various design parameters like breakthrough time (tb), adsorption capacity (qeq), and effective bed height (HB) of the adso...
