Failure to control biofouling in industrial water systems can lead to reduced system efficiency, microbiologically influenced corrosion, and increased downtime. Water treatment programs that include a combination of oxidizing and non-oxidizing biocides provide a broad-based approach to microbial control to minimize the negative impact of biofouling. In this paper, we will discuss the value of non-oxidizing biocides and industry best practices to control biofouling in cooling systems. The paper will discuss recent innovations in solid biocides and the numerous advantages over their liquid counterparts. Synergy between oxidizing and non-oxidizing biocides will also be discussed and treatment recommendations presented.
