Biofouling is one of the most significant types that occur in seawater coolant heat exchangers. Biofouling occurs in two different forms: microbial fouling and macrobial fouling. Microbial fouling occurs when microorganisms attract and stick to the heat exchanger tubes. These organisms can be anything from bacteria to slimes and algae. Macrobial fouling occurs when larger macro organisms attach themselves to the heat exchanger walls. When using seawater coolant these organisms can range from mussels to seaweed, mollusks, and any other organisms. Normally a biofilm is created and this allows the organisms to attach to the film rather than directly on to the metal. This biofilm is generally created by the growth of bacteria or other microorganisms on the tube walls. This way both microbial and macrobial fouling can occur in a mutual process. The microbial fouling creates the biofilm that allows the perfect opportunity for macrobial fouling to initiate. In order for the biofilm to grow, the right conditions must be present. Biofouling can materialize with or without oxygen using aerobic or anaerobic organisms. Previous: Home Next: How does it occur?
