Which of the following statements describes the approximate relation between the feed water entering the unit shown in the illustration and brine being removed? Illustration MO-0111

Correct Answer: Option A — Seventy-five percent of the feed water entering the unit is removed as brine.

To prevent excessive concentration of salts and scale buildup on heat transfer surfaces, marine distillers typically operate with a high blowdown rate. Removing approximately 75% of the feed water as brine ensures that the concentration of dissolved solids remains within acceptable limits for safe and efficient operation.
