Question 1 of 27070

Which of the following desalination plants will always require a sterilizer when providing water to a potable water system?

🔍 Key Concepts

• Potable water standards for ships and why biological contamination is a concern • How different desalination processes (thermal vs membrane/reverse osmosis) remove salts vs microorganisms • Which systems produce water that may still contain bacteria or viruses even when salts are removed

💭 Think About

• Think about which desalination process mainly removes dissolved salts but may allow microorganisms to pass through or grow in the product water system • Ask yourself: which type of plant produces water at relatively low temperature, so it does not get a built‑in ‘pasteurization’ effect? • Consider which plant type is commonly specified in marine practice as needing post‑treatment/sterilization before being used as drinking water

✅ Before You Answer

• Identify which options are thermal distillation types (involving boiling/evaporation and condensation) and which are membrane types • For each type, consider whether the outlet water is hot enough long enough to reliably kill microorganisms • Verify which system is known in merchant marine practice to require a UV, chlorination, or similar sterilizer in the potable water line by design
