🚰 GAC Adsorption (Calgon Filtrasorb, EBCT 10-20 min, Carbon Usage Rate CUR lbs/1000 Gal)

Potable Water GAC Contactors & CUR Calculator

Size Granular Activated Carbon (GAC / Calgon Carbon Filtrasorb 400 / Cabot Norit) pressure vessels removing PFAS, taste & odor compounds (MIB / Geosmin), and disinfection byproduct precursors: calculate Empty Bed Contact Time ($EBCT = 10 ext{ to }20 ext{ minutes}$), model Carbon Usage Rate ($CUR ext{ in lbs GAC / 1,000 Gallons}$), and municipal water yields.
