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/C<sub>0</sub> 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/C<sub>0</sub> 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.
