Microbial Control in Cooling Water

By Chemical Engineering |

Three chlorine-based strategies for controlling microbial load in industrial cooling water are evaluated here Industrial cooling-water systems are critical to the success of many chemical process industries (CPI) operations. Proper operation of cooling-water systems supports the financial drivers of energy efficiency, asset preservation and water savings, while optimizing overall process performance. When maintained properly, industrial cooling-water systems help enable processes to run seamlessly. Selecting the appropriate water-treatment solution for an industrial cooling-water system is critical, and typically includes consideration of mechanical, operational and chemical components of the system (Figure 1). Figure 1. Microbial control must be considered for cooling tower systems to maintain operational efficiency[/caption] Among the important aspects of cooling-water treatment is the control of microbes. Biological control in an industrial water system is important for maintaining optimal performance in three areas: scale prevention, corrosion inhibition and fouling control. Failure to effectively control microbes in cooling water can cause the system to suffer from diminished operational efficiency, premature equipment failure,…
