Register today for our On-Demand Webinar on Side Stream Filtration for Cooling Towers. Cooling towers are an integral component of many refrigeration systems, providing comfort or process cooling across a broad range of applications. In this Webinar, we will be discussing why it is important to consider the use of a side stream filtration system, specifically High-Efficiency Sand Filtration, to remove particle debris down to sub-micron sizes.
Cooling tower systems operation is most efficient when the heat transfer surfaces are clean. However, these are dynamic systems due in part to their operating environment and because of the nature of their application. Cooling towers operate outside and therefore are open to the elements, making them susceptible to dirt and debris carried by the wind. Further, they often experience wide load variations and their operation can be significantly influenced by the quality of the water used for makeup in the system.
The combination of process and environmental factors can contribute to four primary treatment concerns encountered in most open-recirculating cooling systems:
Side stream filtration systems reduce suspended solids and debris in the system cooling water, which leads to less fouling in the system. Decreasing suspended solids can also help reduce biological growth in the system because suspended solids are a good source of food for microbiological organisms. Decreasing biological growth in turn helps to reduce microbiologically influenced corrosion. In addition, scaling can be reduced from side stream filtration by limiting fouling and corrosion byproducts which can also contribute to scale formation on the heat exchange surfaces. Effectively managing these conditions can optimize system performance, often resulting in moderate to significant energy and water savings.
