  43. Final Jeopardy Chlorinaton

  44. Final Jeopardy Label and describe what is happening in each zone (include X) X

  45. Final Jeopardy Label and describe what is happening in each zone (include X)

  46. Breakpoint Chlorination Zone 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. Chlorine demand is difference between applied chlorine and the chlorine residual at any two points on the breakpoint curve.
