APPLICATION
The use of granular Activated Carbon in wastewater treatment systems is a proven process for removal of organic compounds. As a tertiary treatment method, carbon adsorption and regeneration have been used to process domestic wastewaters contaminated with industrial wastes of organic origin as well as biologically treated waste waters. Activated Carbon, when contacted with water containing organic material, will remove these compounds selectively by a combination of adsorption of the less polar molecules, filtration of the larger particles, and partial deposition of colloidal material on the exterior surface. The quantity of Activated Carbon required will depend upon the degree of contamination.
MIXING AND HANDLING
Fluids may be filtered through Activated Carbon or the Activated Carbon may also be added directly to a contaminated fluid to remove impurities. It is advisable to use a dust mask and eye protection while mixing all powdered products.

Label
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.
LABEL PROPERTY
An amorphous from of carbon characterized by high adsorptivity for many gases, vapors, and collodial solids.
Used for water and air purification, solvent recovery, waste treatment, removal of sulfur oxide from stack gases and “clean” rooms as deodorant, and for air conditioning
