Residual vs free chlorine
WebA colorimetric method can be used to determine free chlorine in water at concentrations of 0.1–10 mg/litre. Other methods allow for the determination of free chlorine, chloramines, other chlorine species, and total available chlorine, and are suitable for total chlorine concentrations up to 5 mg/litre. WebSep 18, 2024 · Free available chlorine is the part of the total chlorine measurement that has not yet reacted with contaminants. Therefore, it is called available or free. The total chlorine in this case is the sum of combined available chlorine and free available chlorine, also called total residual chlorine. Advertisement.

WebThe conversion to free chlorine, in conjunction with increased flushing activities, assists in removing excess film from the distribution system and also starves these bacteria. The chlorine conversion helps the system return to an environment where the disinfectant residual can be maintained. WebOnly two forms of chlorine have disinfecting properties: free chlorine and combined chlorine. Free chlorine, which is by far the better disinfectant, is produced when sodium hypochlorite or chlorine gas is added to water. Combined chlorine is monochloramine and dichloramine, compounds formed by the reaction between free chlorine and ammonia.
