Question

question 6 of 10
what should you do if you
take a reading and find tds is
too high?
choose an option below
nothing; high tds drives
tower efficiency.
blowdown the tower and
add make - up water.
increase the feed for
microbial control
chemicals.
raise the discharge
temperature of the cooling
tower.

Explanation:

Total Dissolved Solids (TDS) build-up in cooling towers reduces efficiency and causes scaling. Blowdown removes concentrated, high-TDS water, and adding fresh make-up water lowers overall TDS levels. Other options are incorrect: high TDS harms efficiency, microbial chemicals do not address TDS, and raising discharge temperature does not reduce TDS.

Answer:

B. Blowdown the tower and add make-up water.
