If the demister used in the device shown in the illustration is improperly installed, which of the following will occur? Illustration MO-0110

Correct Answer: Option D — There will be an increase of chlorides measured at the distillate pump salinity cell.

The demister, or moisture separator, prevents brine droplets from being carried over into the condenser with the vapor. If improperly installed, these droplets bypass the separator, contaminating the distillate. This carryover is immediately detected as an increase in chlorides at the salinity cell, indicating poor water quality.
