We know that phrase all too well, as the one Ebenezer Scrooge shouts out in the famous book A Christmas Carol. To a fuel manager, however, it means something entirely different but equally scary. We’re talking about Hydrocarbon Utilizing Microorganisms, commonly known as H.U.M. Bugs.
There are at least 27 types of microbes that break down hydrocarbon (petroleum) products, including bacteria, fungi and yeast. Some refer to them as algae, but no algae can occur in hydrocarbon products – just H.U.M. bugs. Carried by air and in water, H.U.M. bug spores enter fuel supplies through vents and filling ports at any point in the supply chain. Once in a fuel supply, they can go virtually undetected but, once given the right conditions for growth, can as much as double their numbers every 20 minutes. At that rate, it doesn’t take long for H.U.M. bugs to dominate an entire fuel system. These bugs create slime or thick microbial matting that blocks fuel filters and injectors, turning the fuel acidic. H.U.M. bugs adhere to metal surfaces and cause Microbial Induced Corrosion (MIC).
ATP (Adenosine triphosphate) is a constituent of all living cells, including bacteria and fungi. Consequently, the presence of cellular-ATP is an indicator of total metabolically active microbial contamination in fuels. ATP is not associated with matter of non-biological origin. So, if you don’t want the past, present, and future ghosts of microbiological contamination issues haunting you, LuminUltra’s 2nd Generation ATP® technology can help.
