Breakpoint ChlorinationBreakpoint ChlorinationZone I: Chlorine is destroyed by reducing agents such as iron, manganese, clay and silt.
Chlorine reduced to chloride
Zone II: Chlorine comes into contact with organics and ammonia. Chloroorganics and chloramines are formed.
Zone III: Chloroorganics and chloramines are partially destroyed. Chloramines are broken down and converted to nitrogen gas which leaves the system
Zone IV: Breakpoint. Beyond this point, free available residual is formed. Some chloroorganics still remain as combined residual.
