One of the most critical categories of cooling tower chemicals is biocides. Cooling towers, if left untreated, can become breeding grounds for bacteria, algae, and other microorganisms. The presence of these organisms can lead to corrosion, scaling, and biofilm formation, all of which can negatively impact system efficiency. Biocides, such as chlorine, bromine, and newer non-oxidizing agents, are employed to control microbial growth. They are usually added on a regular schedule or as part of a shock treatment to eliminate existing contaminants, thereby enhancing the overall health of the cooling system.
Headaches and feelings of anxiety may arise for some users, particularly if they are sensitive to the stimulatory effects of PQQ. As PQQ influences energy metabolism, some people might experience increased energy that could potentially lead to feelings of jitteriness or anxiety, especially if consumed in excess or close to bedtime. For those predisposed to anxiety or those with a history of migraines, careful monitoring of dosage is recommended.
