How much available chlorine is gas chlorine considered to have?

Gas chlorine is considered to have 100 percent available chlorine because it is in its pure gaseous form and does not contain other components that would dilute its chlorine content. This means that when gas chlorine is applied to water for disinfection, all of it can actively participate in the disinfection process, making it highly effective as a sanitizing agent. This high concentration is essential for achieving rapid and effective reduction of pathogens in water treatment applications.

In contrast, other forms of chlorine, such as calcium hypochlorite or sodium hypochlorite, may have various percentages of available chlorine due to the presence of other chemicals or impurities in the compound. When evaluating disinfection options, understanding the available chlorine content ensures that the right dosage can be applied for effective microbial control.
