Full Description

This powerpoint presentation begins by providing a brief overview of adsorbent systems that are increasingly applied to remove compounds inwater and wastewater. Specific adsorbents presented include:activated carbon;activated alumina; and,ion exchange. Methods,adsorption concepts, andcolumn configurations are presented, and presentation conclusions indicate that:mass transfer zone, C/Csub0/sub target, and breakthroughcurve shape are key parameters needed to determinecolumn configuration with lower adsorbent usage;single component breakthrough curves can be normalizedto similar curves, and therefore have similar processselection diagrams; column configurations with short MTZs do not havesignificant differences in adsorption usage rate; C/Csub0/sub target only becomes important at % MTZs longerthan about 60%; and,bypass blending with lead-lag columns at maximumbypass results in a lower adsorbent usage rate than twoparallel columns with bypass and configurations withoutbypass. Includes tables, figures.
