This powerpoint presentation begins by presenting the study objectives that include the following: to model the
simultaneous removal of multiple contaminants
by anion exchange. This was done by using the following steps:
model arsenic and nitrate removal;
model arsenic and nitrate regeneration;
model partial vs. complete regeneration; and,
model multiple ion exchange columns in parallel. The experimental approach included the following: measure resin capacity and resin-anion affinity
factors;
use experimental data to curve-fit an actual
effluent curve and determine best-fit number of
stages (mass-transfer zones);
model nitrate and arsenic removal for a number of
different water qualities such as
when nitrate exceeded its MCL,
when arsenic exceeded its MCL, and
when both nitrate and arsenic exceed their MCL. Includes tables, figures.
