Chemicals are added to cooling tower water to address the following problems except-

• A. Algae
• B. Slime
• C. Taste
• D. Mold

Answer: (C)

Cooling tower water treatment focuses on keeping the water free of biological growth and mineral problems that can reduce heat transfer and damage equipment. Algae, slime, and mold are all forms of microbial growth or biofilm that can form in the tower and on surfaces, leading to poorer heat transfer, increased corrosion risk, and fouling. Chemicals such as algaecides and biocides are used to prevent or control these organisms, keeping the system clean and efficient. Taste, however, is a concern for potable water quality, not for cooling tower water, since the water in a cooling tower isn’t meant for drinking and its taste isn’t a target of the treatment. So taste is the issue that isn’t addressed by the chemicals used in cooling towers.
