CENTAUR CATALYTIC/ADSORPTIVE CARBON
CENTAUR® 12X40 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. CENTAUR 12x40 is produced from bituminous coal
using a patented process. Although it is not impregnated with metals or alkali, it displays the catalytic
functionality of these materials. In most cases, it can be reactivated and does not present the disposal
concerns associated with impregnated carbons.
CENTAUR 12X40 can be utilized in the liquid phase for the promotion of oxidation, reduction,
decomposition, substitution, and elimination reactions. Specific applications include chloramine,
hydrogen sulfide, and iron removal from drinking water. This product is particularly suited for use in
residential and commercial water filters, for treatment of process water in the bottling and soft drink
industries, and for aquarium water treatment. CENTAUR 12x40 combines a fine pore structure for
enhanced adsorption of trace contaminants with high catalytic activity for their elimination. Thermal
reactivation is an option for recycle and reuse of this product to minimize operating costs and eliminate
disposal concerns.
CENTAUR 12x40 is intended primarily for use in liquid phase systems to promote catalytic reactions.
Depending on the reactant concentrations, the required contact times are usually less than five minutes.
The backwashed and drained density of the product is typically 33 lb/ft3.

CENTAUR ACTIVATED CARBON - COCONUT SHELL
CENTAUR-CS 12x40 removes both chloramine and hydrogen sulphide from potable water. Centaur is
outstanding in VOC removal, taste and odor control and in operating efficiency when compared with
traditional activated carbons.
Standard Centaur is a coal based catalytic carbon, CENTAUR-CS is entirely coconut shell carbon
and is processed the same as the original giving it the same properties. The coconut shell variety
as with all coconut shell carbon doesn't have the same capacity as the original, but it does give an
economical option.

FILTRASORB 200 BITUMINOUS COAL ACTIVATED CARBON
FILTRASORB® 200 is a granular acid rinsed activated carbon for the removal of taste and odor
compounds, disinfection by-products, low level volatile organic compounds, and other targeted
compounds from potable water.
This product was specifically developed for groundwater applications. This activated carbon is
manufactured from selected grades of bituminous coal to produce a durable granular product capable
of withstanding the abrasion associated with repeated backwashing, air scouring, and hydraulic
transport. The product is designed to comply with all the applicable provisions of the AWWA Standard
for Granular Activated Carbon, edition B604-05, the stringent extractable requirements of ANSI/NSF
Standard 61, and the Food Chemicals Codex.

Resins, Media & Chemicals
Calgon Carbon produces and sells a broad range of activated, impregnated or acid washed carbons in
granular, powdered or pellet form. Granular Activated Carbon (GAC) particles are irregular in shape and
generally used in fixed filter beds for continuous flow purification processes.
