Activated Carbon Media

Granular Activated Carbon
Activated carbon (AC) is a natural material derived from bituminous coal, lignite, wood, coconut shell etc., activated by steam and other means. Carbon is very popular due to its ability to correct many water quality problems.

Benefits

  • Improve taste and remove odors
  • Dechlorination of water
  • Remove color from water
  • Removal of organic substances
  • Removal of synthetic organic substances
  • Clear water for drinking, bathing and cooking!

Adsorption Influencing Factors

Temperature  
Most effective 60°F - 80°F.
pH
Most organics in water are more soluble at pH lower than 7.0.
Contact Time
Very important to achieve proper flow rates for any adsorption system to function properly.


Carbon Media types

Bituminous Basic coal based granular media
Coconut shell Superior level of hardness; high activity level; trihalomethane removal; longer life expectancy;
Acid washed Increases adsorptive capacity of carbon base and lowers the level of impurities.
Catalytic Specialized carbon media to remove hydrogen sulfide gas and chloramines.


Standard Operating Conditions

Service flow rate 2 - 6 gpm/cu.ft.
Freeboard 20%
pH 6.5 – 7.5

Contaminates Adsorbed

  • Chlorine
  • Organic Chemicals
  • Fertilizers
  • TCE (Trichloroethylene)
  • EDB (Ethylene dibromide)
  • THM (Trihalomethanes)
  • Sediment
  • Chemical odor
  • Pesticides
  • Detergents
  • Chloramines

Note: Service flow rates are calculated at 2-6 gpm/ft3 for standard taste, odor and chlorine removal application using bituminous carbon. Chloramines and TDS applications will require lower service flow rates and longer empty bed contact time or specialized carbon formulations.

Catalytic® Granular Activated Carbon

Hydrogen sulfide and chloramines removal
Catalytic carbon is a liquid phase virgin activated carbon that has been manufactured to develop catalytic functionality. The product is unique in that it concentrates reactants via adsorption and then promotes their reaction on the surface of the pores.

Features & Benefits

  • Catalytic activity allows for smaller more compact system sizing and lower capital requirements.
  • No safety concerns with exotherms or toxicity like some impregnated medias.
  • Improved trace organic capacity per unit volume.
  • High hardness reduces fines and losses due to handling.
  • Works with low oxidant levels and limits the need for chemicals.
  • Simple and reliable equipment design that will handle spikes in concentration without metering of chemicals.
  • Reduced carbon requirements reduce operating costs.
  • Enhanced carbon media performance for a greater degree of contaminant removal at reduced costs.
  • Thermal reactivation is an option for recycle and reuse to minimize operating costs and eliminates disposal concerns.

Applications

  • Chloramines
  • Hydrogen sulfide
  • Taste and odor
  • VOC removal
  • Iron removal
  • Residential water filters
  • Commercial water filters
  • Bottling and soft drink industries
  • Aquarium water treatment

Specification

Moisture content (as packaged) Max. 5%
Total ash content Max. 4%
Ball-pan hardness Min. 98%
CTC activity Min. 50%

Typical Properties

Surface area (BET) 1060 m2/g
Apparent density 514 kg/m3
Bed density, backwashed and drained 437 kg/m3

Design Considerations
Catalytic carbon is produced from bituminous coal using a patented process for the use in liquid phase
systems to promote catalytic reactions. The reactant concentration determines the effective contact time.
Although it is not impregnated with metals or alkali, it displays the catalytic functionality of these materials.

Safety message: Wet activated carbon preferentially removes oxygen from air. In closed or partially closed
containers and vessels, oxygen depletion may reach hazardous levels. If workers are to enter a vessel containing
carbon, appropriate sampling and work procedures for potentially low oxygen spaces should be followed, including
all applicable federal and state requirements.
