WebMar 19, 2024 · Ammonia in the water supply is undesirable as it strips away the Chlorine residual which then requires the need to use more Chlorine. What makes chloramine treatment so effective is chlorine’s quick formation with ammonia (NH 3 ). (Ammonia is a compound of Nitrogen and Hydrogen.) (1.9.1) Cl 2 + NH 3 → NH 2 Cl + HCl. WebJun 29, 2024 · A simple way to achieve this is by increasing the chlorine PPM by ten times the total combined chlorine. To ensure that the shocking process achieved the breaking point, check that the free chlorine and total chlorine levels are equal. Both levels should also rise at the same time if more chlorine is added to the water.

Breakpoint chlorination is the point where chlorine levels exceed the oxidant demand, and the water begins to build a residual of free available chlorine (FAC). Theoretically, exceeding the “breakpoint” prevents increased levels of disinfectant byproducts (like chloramines). See more Let's look at the graph above. When you first add chlorine to water, it immediately begins to oxidize metals like iron and manganese, which reduce chlorine. This initial reaction wipes out a certain portion of chlorine, which is … See more As noted before, chloramines are disinfectants--which is why they are referred to as disinfectant byproducts (DBPs).
