The warm, moist environment of large, industrial cooling towers is highly conducive to microbiological growth. Left unattended, microbiological growth can negatively impact heat transfer and cause under deposit corrosion, which can significantly damage capital assets. In addition, the potential for health risks associated with specific pathogens (such as Legionella) increases if the pathogen risk is not assessed and controlled.
Biosperse microbicides comprise a family of products that effectively control a broad spectrum of microbes, including bacteria, fungi and algae, in industrial open re-circulating, once-through, and closed-loop cooling water systems. 
Recommendation for the appropriate Biosperse product and the corresponding application method will depend upon a number of factors, including the nature and extent of microbiological contamination, the type and volume of the system being treated, the degree of control desired and system retention time.
