🔍 Key Concepts

• Residual disinfectant means a small amount of disinfectant that remains in the water to keep it safe as it travels through the system. • How UV (ultraviolet) systems work compared with chemical disinfectants like chlorine or bromine. • Where the disinfectant is added in the system (discharge line vs. recirculation line) and how that affects the water in the tank and distribution piping.

💭 Think About

• Which option describes a system that kills or inactivates organisms but does not leave any chemical behind in the water? • For each chemical system listed (brominator/chlorinator), ask yourself: does this chemical usually leave a measurable residual in the potable water? • Think about why ships test potable water for chlorine or bromine residual but do not normally test for a residual of one of the listed methods.

✅ Before You Answer

• Identify which method is a physical disinfection process versus chemical disinfection processes. • Confirm which methods are specifically designed to leave a measurable residual disinfectant in the potable water system. • Make sure you understand that the question is asking for the system whose main disadvantage is lack of residual protection in the tank and piping.
