This powerpoint presentation begins by presenting the study objectives that include the following: to model thesimultaneous removal of multiple contaminantsby 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 affinityfactors;use experimental data to curve-fit an actualeffluent curve and determine best-fit number ofstages (mass-transfer zones);model nitrate and arsenic removal for a number ofdifferent water qualities such aswhen nitrate exceeded its MCL, when arsenic exceeded its MCL, andwhen both nitrate and arsenic exceed their MCL. Includes tables, figures.
