Dirty fuel is a fact of life. Even with the development of cleaner burning fuels, contaminants are still a major concern when it comes to fuel systems. Micro-organisms can quickly become a major problem. Colonies of fungus and bacteria feed on your fuel.Commonly known as algae, they spread rapidly in the presence of moisture. They easily spread from one tank to another by riding in the fuel. As these micro-organisms accumulate, they will spread through your data center's generator fuel system and quickly plug the fuel filter. Most end users will simply add a biocide to kill the fungus. While this does kill the bacteria, it does not remove the growth media from the tank. Biocides are also very toxic and cause chemical burns when they come in contact with the human skin.
