Chemicals in Drinking Water: Chloramines
www.chloramine.orgDrinking water As already mentioned, international guidelines for drinking water quality suggest that no short- or long-term health effects have been associated with chloramines in chlorinated drinking water. Chloramines are therefore considered as safe water treatment chemicals when present at the normal concentrations detailed above.

GRANULAR ACTIVATED CARBON (GAC) FACT SHEET
www.wqa.orgThe deactivation of chloramine can be accomplished with GAC but the filter has to be sized about four times the size of a regular GAC filter used for chlorine. To increase the EBCT, filter units can be strung in series. Catalytic carbon, which has an oxidizing capability is more effective for chloramine reduction with EBCTs of about 5 minutes.
