What is the primary method used to remove total chlorine in water treatment systems?

The primary method used to remove total chlorine in water treatment systems is granulated activated carbon filters. These filters contain activated carbon, which has a large surface area and porous structure that effectively adsorbs chlorine and chlorine byproducts from the water. The adsorption process occurs as water flows through the carbon medium, allowing the chlorine molecules to bond with the carbon, thereby reducing their concentration in the treated water.

While carbon filtration is a broader term that may encompass various forms including both granular and powdered activated carbon, the choice of granulated activated carbon is specifically relevant in this context due to its efficient flow characteristics and capacity for handling larger volumes of water.

Reverse osmosis can also remove chlorine, but its primary function is to remove a wide range of dissolved solids, contaminants, and other impurities through a semipermeable membrane. Using reverse osmosis as a standalone method for chlorine removal is less common and typically not as efficient as activated carbon.

Ultraviolet light is effective for disinfection and inactivating microorganisms but does not specifically target total chlorine removal. Its role is mainly to reduce pathogens rather than to remove chemical contaminants like chlorine.

In summary, granulated activated carbon filters are specifically designed for the effective adsorption of chlorine, making them the primary choice for chlorine
