Municipal Drinking Water Treatment

Clean, safe drinking water is a luxury taken for granted by some. For many others, lack of access is a source of daily suffering.

Calgon Carbon Corporation offers an array of purification solutions for municipal drinking water– all delivered through a comprehensive global service network.

These can be used independently or in combination to meet your needs and/or regulatory standards in the most economical way possible.

Surface Water

The U.S. Environmental Protection Agency (EPA) and most state-based departments of health consider adsorption by granular activated carbon (GAC) to be the best available technology for the removal of many organic materials in surface water. On its own, on GAC can facilitate the removal of:

  • PFAS to >99.99% efficiency
  • Disinfection byproducts (DBPs) associated with chlorine and alternative disinfectants
  • Algal toxins, such as microcystin-LR and anatoxin-A
  • Bacteria, viruses and parasites such as cryptosporidium and giardia
  • Endocrine-disrupting compounds (EDC)
  • Pharmaceuticals and personal care products (PPCP)
  • Taste and odor-causing compounds (T&O)
  • Organic materials from decaying plants and other naturally occurring matter (NOM) which serve as the precursors for DBPs



Groundwater is drawn from underground aquifers and can require treatment to remove emerging contaminants, industrial chemicals, natural minerals, viruses and bacteria. To address these water purification challenges, Calgon Carbon can design groundwater treatment systems that incorporate GAC and the elimination of organic contaminants. Additionally, ion exchange technology can assist with the removal of inorganic compounds.

Technologies/Solutions for the Treatment of Municipal Drinking Water:

Whether your drinking water is sourced from groundwater, surface water or a combination of both, Calgon Carbon offers two purification technologies:

Granular Activated Carbon (GAC)

Granular activated carbon (GAC) is a very reliable solution for a variety of water treatment challenges, and more water providers are adopting it every year. Use of GAC provides water utilities with an efficient and cost-effective means to prevent the formation of disinfection byproducts (DBPs) while also removing other organic contaminants, including PFAS, found in both surface water and groundwater.

Ion Exchange Technology

Ion exchange technology is a cost effective process to treat municipal water contaminated by inorganic compounds. These compounds include but are not limited to:

  • Nitrate
  • Perchlorate
  • Hexavalent Chromium (Cr VI)
  • Color
