GRANULAR ACTIVATED CARBON (GAC) FACT SHEET
The use of granular activated carbon (GAC) for water purification became common around the start of the 20th century (1906) when the “activation” process was applied to charcoal (which had been used for centuries). Thermal activation of charcoal greatly improves its pore volume, surface area and
Activated Carbons - Granular Activated Carbon Wholesale
Activated carbon is useful in drinking water treatment because it acts as an adsorbent, and can effectively remove particles and organics from water. These organics are of great concern in water treatment because they react with many disinfectants, especially chlorine, and cause the formation of disinfection-by-products, DBP's .These DBP's are

Activated Carbon Drinking Water Filtration Treatment Trace
Powdered activated carbons (PAC) are used in batch treatment processes, whereas granular (GAC) grades are generally used in fixed filter beds, with the water passing through the filtration medium. The advantage of using GAC for water treatment is that the spent carbon can normally be regenerated via thermal reactivation.
ACT - Activated Carbon for Drinking Water Treatment
Depending on which type of water treatment plant design is considered, either powdered activated carbon (PAC) or granular activated carbon (GAC) could be used. Our Australian made drinking water PACs and GACs are WQA certified to meet the NSF/ANSI 61 standard and have the WQA Gold Seal Certification.

GRANULAR ACTIVATED CARBON FOR WATER & WASTEWATER TREATMENT
The specific capacity of a granular activated carbon to adsorb organic compounds is related to: molecular surface attraction, the total surface area available per unit weight of carbon, and the concentration of contaminants in the wastewater stream. The basic instrument for evaluating activated carbon use is the adsorption isotherm. The isotherm
CAFE: Activated Carbon Treatment for Drinking Water
Granular activated carbon (GAC) treatment is most common for private water systems. Granular activated carbon is an effective filter for removing organic chemicals that may be in drinking water. Many other small devices use carbon that has been pressed into a solid block. Use of block carbon may result in a significant drop in home water pressure.
C. Johnson, in Comprehensive Water Quality and Purification, 2014. 220.127.116.11.1 PAC. Activated carbon treatment at water treatment plants is typically installed to provide removal of natural organic compounds, taste and odor compounds, and synthetic organic chemicals. Activated carbon adsorption physically attaches gas or liquid phase molecules to the surface of the activated carbon.
Summary of Cyanotoxins Treatment in Drinking Water
Granular activated carbon (GAC): Effectiveness of GAC adsorption varies based on type of carbon, pore size, type of cyanotoxin, and other water quality parameters such as NOM concentration. GAC is effective for microcystins, and likely effective for cylindrospermopsin, anatoxin-a and saxitoxin.
