RHG Catalytic Carbon blocks contain specially formulated catalytic carbon. This is a specially enhanced carbon developed through an advanced process starting as Activated Carbon. By altering the electron structure of the carbon, it enhances its catalytic capability, enabling it to cause chemical reactions without changing its structure. As a result, it promotes a wide range of chemical reactions where conventional carbons are not effective.

Catalytic Carbon provides another alternative to chemical treatment. Essentially, catalytic carbon is activated carbon with a modified carbon surface. Chloramines are used to control bacterial growth in distribution systems and to reduce the formation of trihalomethanes (THMs). Most Municipal water systems are now using chloramines to treat water (versus free chlorine), which dramatically reduces membrane performance (and lifetime). Chloramines should be treated as a mild oxidant and are recommended to be removed or reduced before contact with reverse osmosis membranes.
