Biofilm results from the metabolism of bacteria and greatly reduce the facility’s affectivity in cooling towers and heat exchangers.   Biofilms continually release microorganisms that can cause infections. The polysaccharides (out of which most biofilms consist) are difficult to oxidize by means of chlorination, which is why even high chlorine amounts only lead to short-term improvements but not to sustainable remediation. TCDO and chlorine dioxide are more effective for biofilm oxidation because they have a higher oxidations potential (redox potential) and are less pH-dependent.
