Catalytic carbon
“Catalytic” or “surface-modified” activated carbon removes chloramines from water
Catalytic carbon is a class of activated carbon used to remove chloramines and hydrogen sulphide from drinking water. It has all the adsorptive characteristics of conventional activated carbons, as well as the ability to promote chemical reactions.
The benefits of using catalytic carbon:
- More effective than conventional carbons; catalytic activity promotes a variety of chemical reactions
- Faster chemical reaction means less carbon and smaller equipment
- Non-impregnated carbon eliminates worries about exothermic reaction, ignition temperature and toxic disposal
- On-site regeneration lowers operating costs and extends service life
- Can be recycled and reused through thermal reactivation
What are chloramines?
Chloramines are added to water as an alternative to chlorine. They inhibit the formation of carcinogenic trihalomethanes (thms) caused by the interaction of chlorine with organic plant materials.
Catalytic carbon is not impregnated with caustic chemicals
Because catalytic carbons have no impregnates, you won’t have to worry about reduced organic odour capacity or the higher bed fire potential of the impregnated carbons. Catalytic carbon is created by altering the surface structure of activated carbon. It is modified by gas processing at high temperatures to change the electronic structure and create the highest level of catalytic activity on carbon for reducing chloramine and h2s in water. This added catalytic functionality is much greater than that found in traditional activated carbons. Catalytic carbon is an economical solution to treat h2s levels as high as 20 to 30 ppm. Catalytic carbon converts adsorbed h2s into sulfuric acid and sulphurous acid which are water soluble, so carbon systems can be regenerated with water washing to restore h2s capacity for less frequent physical change-outs.
