  • What is granular activated carbon (GAC) filtration?
  • 1. Introduction Granular activated carbon (GAC) filtration is widely applied in advanced drinking water treatment plants for its filtration and adsorption capabilities as a barrier for undesired macro- and micro-pollutants , , .
  • What is a granular activated carbon filter?
  • A filter with granular activated carbon (GAC) is a proven option to remove certain chemicals, particularly organic chemicals, from water. GAC filters also can be used to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide (rotten eggs odor) or chlorine.
  • How does a GAC filtration system work?
  • The GAC filtration system uses the physical properties of natural carbon to remove a wide range of contaminants from drinking water, including HFPO‐Dimer Acid (GenX) and similar polyfluorinated compounds (PFAS) by passing the water through filters containing GAC, which traps, or adsorbs, the chemicals.
  • Does a GAC filter remove chemicals from water?
  • A filter with GAC can remove certain chemicals, particularly organic contaminants, from water, as well as chemicals that produce odors or tastes to water such as hydrogen sulfide or chlorine.
