Optimizing the Placement of GAC Filtration Units
The costs of granular activated carbon (GAC) filter-adsorbers (second-stage GAC filtration) were compared with those of the sand replacement option (first-stage GAC filtration). Simulation models of total organic carbon (TOC) adsorption and particle removal were used to describe filter performance....
