Granular Activated Carbon

A9031A

Water Tech supplies a variety of Granular Activated Carbon (GAC, PAC) filter media to remove organic compounds, color, and / or extract free chlorine from water for reverse osmosis (RO), nano filtration (NF), manufacturing processes, discharge, and other applications.

Granular Activated Carbon remove impurities through adsorption and contact time. Free chlorine removal is the result of residence time in contact with the carbon, rather than filter surface loading, with standard design of typically 2 to 6 gpm / ft3 of carbon bed. Chloramines are significantly harder to remove than chlorine, and require an extended period of contact with the activated carbon, referred to as empty bed contact time (EBCT).

Our Activated Carbon Media Types Include:

  • Bituminous: Coal based granular media.
  • Coconut Shell: Superior hardness; high activity level; trihalomethane removal; long life.
  • Acid washed: Increased adsorptive capacity, low pH applications.
  • Catalytic: Specialized to remove hydrogen sulfide gas, iron, and chloramines.

 

Contaminants Removed by Our Granular Activated Carbon Include:

  • Chlorine
  • Color
  • Organic Substances and Chemicals
  • Fertilizers
  • TCE (Trichloroethylene)
  • EDB (Ethylene dibromide)
  • THM (Trihalomethanes)
  • Sediment
  • Chemical Odor
  • Pesticides
  • Detergents
  • Chloramines
  • Others

 

Water Tech carbon filter tanks and systems are also available in all sizes.
