This powerpoint presentation begins by providing a brief overview of adsorbent systems that are increasingly applied to remove compounds in water and wastewater. Specific adsorbents presented include: activated carbon; activated alumina; and, ion exchange. Methods, adsorption concepts, and column configurations are presented, and presentation conclusions indicate that: mass transfer zone, C/C₀ target, and breakthrough curve shape are key parameters needed to determine column configuration with lower adsorbent usage; single component breakthrough curves can be normalized to similar curves, and therefore have similar process selection diagrams; column configurations with short MTZs do not have significant differences in adsorption usage rate; C/C₀ target only becomes important at % MTZs longer than about 60%; and, bypass blending with lead-lag columns at maximum bypass results in a lower adsorbent usage rate than two parallel columns with bypass and configurations without bypass. Includes tables, figures.
