CENTAUR® NDS 12x40
- Chemical Family
- Active Carbon
CENTAUR® NDS 12x40 is a liquid phase virgin activated carbon that has been manufactured to exhibit enhanced 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 NDS 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 CENTAUR NDS 12x40 can be reactivated and does not present the disposal concerns associated with impregnated carbons.

- Safety
Wet activated carbon can deplete oxygen from air in enclosed spaces. If use in an enclosed space is required, procedures for work in an oxygen deficient environment should be followed.

- Features
Combines a fine pore structure for enhanced adsorption of trace contaminants with high catalytic activity for theirelimination; Not impregnated; Improved trace organic capacity; High hardness; Simple equipment design (no pumps or addition of chemicalsrequired); Smaller system size as compared to standard carbons; lower capital requirements; No safety concerns with exotherms or toxicity as with impregnatedcarbons; Wide applicability; can eliminate chemical addition
- Regulatory
This product complies with the requirements for activated carbon as defined by the Food Chemicals Codex (FCC) (8th Edition) published by the U.S. Pharmacopeia, is certified as a component to the NSF/ANSI 42 – Drinking Water Treatment Units – Esthetic Effects standard, and meets the requirements for arsenic level for a raw material as defined by the consent judgment dated September 9, 2008 for case number RG08-386432 for California Proposition 65 – Cal. Health & Safety Code §25249.5 et seq.. The product is designed to meet the stringent extractable metal requirements of NSF Standard 42 test protocol.
- Technology
- Industrial Additives & Materials
- Design Considerations
CENTAUR NDS 12x40 is intended primarily for use in liquid phase applications where maximization of catalytic reaction is desired. Depending on the reactant type, concentrations and process conditions, the contact time in fixed bed systems is typically less than seven minutes.
- Recycling and Reactivation
Though CENTAUR is 100-percent freshly manufactured virgin GAC, it can be recycled and reused through thermal reactivation to restore its adsorptive capacity. This eliminates the costs and long-term liability associated with the disposal of spent GAC, and provides customers with a consistent, reliable supply of filtration media.
