Cooling water intake valves succeed in microbiologically influenced corrision (MIC) environment 

Cooling Water Intake Valves MIC.JPGMIC is corrosion caused by the presence and activities of microorganisms including bacteria, fungi, and microalgae in water. Microorganisms do not consume the materials they adhere to but can change the environment significantly to result in corrosion. The bacteria can develop into a colony called a biofilm and adhere to metal and nonmetal surfaces like elastomers. Biofilms are impacted by pH, temperature, velocity and surface finish. They grow well at moderate pH levels, ambient temperatures, slow velocity or stagnant water, and on rough surfaces. Under these conditions biofilms can be an issue for many industries such as power plants, refineries, steel mills, paper mills, and marine environments making them prone to MIC.
