Where would a salinity cell be installed in...

🔍 Key Concepts

• Purpose of a salinity cell in an evaporator/distilling plant • Where distillate (fresh water) actually leaves the system and is sent to tanks or use, versus where condensate is still being reclaimed internally • What type of water flows through each listed line (distillate, brine, or condensate) in a double-effect distilling plant

💭 Think About

• For each option, think: is this a point where I need to continuously monitor water purity before it is accepted as fresh water? • Ask yourself what would happen if salt water leaked into the second effect or condenser—at which line would it be most important to detect high salinity to protect the potable water tank? • Consider whether a salinity cell is normally placed on lines that stay within the plant (internal recirculation/drain) or on lines that deliver product water out of the plant.

✅ Before You Answer

• Identify which line(s) actually carry product distillate to storage or users, not just drains or internal returns • Confirm which of the listed locations would carry water that, if contaminated, must be automatically dumped or diverted instead of sent to the fresh water system • Verify whether salinity cells are usually installed on every internal drain or mainly on the final distillate outlet(s).
