A chemical treatment designed to effectively inhibit the growth of microorganisms is known as a biocide. Health hazards, the breakdown of chemicals, the formation of biofilms, heat transfer losses, flow restriction, and under deposit corrosion are all potential outcomes of uncontrolled microbial growth. Typically, the control of microbial growth is achieved by ensuring that systems are cleaned upon startup and on a regular basis as needed, preventing system contamination, and applying a Chemicals either continuously or through a program of shock dosing.
