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

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

The demister is critical for removing entrained brine droplets from the rising vapor. If improperly installed, brine carryover occurs, contaminating the distillate. This contamination is immediately detected as an increase in chlorides by the salinity cell located at the distillate pump discharge, indicating poor water quality.
