Factors affecting Chlorine Demand in waste water treatment ...

The breakpoint is the point at which the ,chlorine demand, has been totally satisfied - the ,chlorine, has reacted with all reducing agents, organics, and ,ammonia, in the water. When more ,chlorine, is added past the breakpoint, the ,chlorine, reacts with water and forms hypochlorous ,acid, in direct proportion to the amount of ,chlorine, added.
