Water Nuggets Practice Exam

Question: 1 / 400

What occurs to chlorine levels before reaching the breakpoint?

Chloramines will form

Before reaching the breakpoint in the chlorination process, the formation of chloramines occurs as a result of chlorine reacting with organic compounds and ammonia present in the water. When chlorine is added to water containing these substances, it initially reacts to form chloramines, which are less effective as disinfectants compared to free chlorine. This transitional phase is crucial because it highlights the consumption of chlorine as it interacts with contaminants before additional chlorine is necessary to achieve a breakpoint—where all chlorine demand has been satisfied and free chlorine is present for disinfection purposes.

Understanding this process helps in managing water treatment effectively, as maintaining appropriate chlorine levels ensures that both chloramines and free chlorine are monitored to provide safe and clean water.
