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
AI Explanation
The correct answer is A) Seventy-five percent of the feed water entering the unit is removed as brine.
This is because in a typical desalination or reverse osmosis system, approximately 75% of the feed water is removed as brine or concentrated waste, while the remaining 25% is the purified freshwater product. This ratio is a common design parameter in these types of water treatment systems, as it allows for efficient operation and disposal of the concentrated brine.
The other options are incorrect because B) is not the typical ratio, C) introduces irrelevant details about specific device numbers, and D) describes a scenario that would not be desirable, as removing brine at a faster rate than the feed water enters could lead to issues with the system's operation.
