Additionally, biocide agents are crucial for controlling microbial growth within the chilled water system. Bacteria, algae, and fungi can proliferate in stagnant water, leading to biofilm formation and clogs in the system. This microbial presence can significantly hinder the system's performance and lead to costly repairs. Chemicals like chlorine dioxide, isothiazolinones, and quaternary ammonium compounds are commonly used to mitigate these risks and ensure the system operates smoothly.
