For Municipalities - Activated Carbon
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 found in both surface water and groundwater.

GAC also removes compounds that cause unpleasant taste and odors in drinking water. It provides an effective barrier against many of the endocrine disrupting compounds as well as pharmaceutical and personal care products now found in our water supplies. Most importantly, GAC accomplishes all of these tasks simultaneously, providing water utilities with a single process to solve multiple problems.

As a leader in the activated carbon industry, Calgon Carbon offers a host of GAC products, systems and services:

  • Granular activated carbon for treatment of taste and odor, disinfection byproducts, emerging contaminants, and other dissolved organics in municipal drinking water.
    • FILTRASORB granular activated carbon - the industry standard for drinking water treatment.
    • PEROXCARB granular activated carbon for hydrogen peroxide quenching in conjunction with UV-AOP systems.
    • CENTAUR granular activated carbon for targeted removal of iron and hydrogen sulfide from water.
    • NSF-certified, CMR brand custom potable reactivation services for environmentally responsible and economical use of granular activated carbon.
  • Superior quality powdered activated carbons (PAC) for taste and odor removal.
  • Standardized, pre-engineered, 'M-Series' adsorption equipment systems for potable water treatment.

Ultraviolet Water Treatment Technologies

Treating water with UV irradiation is highly effective because it attacks harmful organisms at the genetic level. By passing contaminated water over ultraviolet lamps with germicidal properties, the UV energy disrupts the DNA in viruses, bacteria, and protozoa, making them unable to reproduce and rendering them harmless. UV is especially helpful to treat chlorine-resistant organisms like Cryptosporidium and Giardia. UV systems coupled with advanced oxidation can also effectively treat taste and odor compounds present in drinking water.

Calgon Carbon's UV systems include:

  • SENTINEL UV disinfection systems for the treatment of Cryptosporidium, Giardia and other harmful pathogens.
  • SENTINEL UV-AOP systems for combined disinfection and taste and odor removal.
    • PEROXCARB granular activated carbon for hydrogen peroxide quenching in conjunction with UV-AOP systems.

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

Strict regulatory requirements are already in place for nitrate across the United States, while perchlorate is regulated in several US states. The U.S. Environmental Protection Agency intends to regulate perchlorate and hexavalent chromium.

Calgon Carbon’s Fixed Bed and Continuous ISEP technology systems are ideally suited to remove all of these compounds, allowing water utilities to comply with both today’s regulations, and tomorrow’s.

Resources and Literature
Innovation is the cornerstone of Calgon Carbon. We were the first to create activated carbon from bituminous coal. We pioneered the use of UV irradiation. And we are at the forefront of ion exchange systems. Our advanced technologies address drinking water concerns helping ensure that tens of millions of people drink clean, safe water every day.
