Which filtration method is used to remove chloramine from water?

Carbon filtration is an effective method for removing chloramine from water due to the properties of activated carbon. Activated carbon has a large surface area that allows it to adsorb a wide range of contaminants, including chloramines, which are commonly used as a disinfectant in water treatment. The process involves the chemical reaction between the chloramine and the active sites on the carbon, effectively trapping the chloramine molecules and preventing them from remaining in the water. This method not only improves water quality by removing undesirable flavors and odors associated with chloramines but is also widely considered the most practical approach for home and commercial water treatment systems when targeting this specific compound.

Other methods like ion exchange can remove certain ions and contaminants but are not specifically effective against chloramines. Microfiltration and ultrafiltration primarily deal with removing larger particles, bacteria, and some viruses but do not effectively target chloramines, making carbon filtration the optimal choice for this purpose.
