How microbiological growth affects cooling systems and in which ways it could be kept under control? |
Microbiological growth can cause fouling in a cooling water system as well as pose a health risk. Algae and bacteria that form sessile deposits can cause under deposit corrosion leading to tube failure. The deposits are also capable of blocking off water flow reducing the efficiency of the cooling system. Bacteria are especially a health hazard in cooling systems as these operate at human body temperature making them an ideal incubator for waterborne human pathogen e.g. Legionella. |
