Causes, Consequence And Prevention Of Microbial Growth In Fuel Tank

Safety, cleaning and proper maintenance of the fuel tank are extremely important for the smooth functionality of agriculture, fleet and marine businesses. The efficiency of operation and the machinery greatly depends on clean and quality fuel. We know how impure fuel can damage the fuel tank of the machine. Therefore, a maintenance strategy is essential to deliver the desired results. Now the question is, what are the impurities in the fuel and what adds these impurities to the fuel.

Microbial Growth

Microbial growth in the tank takes place because of the bacterial and fungal growth. The fuel is the source of food for bacteria and fungus. Kerosene and diesel are preferred by these two. Gasoline, on the other hand, contains elements like lead which are not less than poisons to bacteria. All fuels contain these microbes to a certain degree. However, there are some conditions that trigger the growth of these microbes. In the absence of these conditions, these are in a harmless state.

Conditions That Trigger Microbial Growth

In the presence of these conditions, these microbes can cause complications. Water, fuel and temperature (50F to 104F) are the factors that trigger microbial growth. There are some vapors of water within the fuel. The condensation of these vapors also contaminates the fuel as water and oil never mix. This water-fuel interface is the place where microbial growth takes place. This growth usually takes place at the bottom of the tank.

Microbes Growth Monitoring Program

This program involves scheduled sampling and testing. This is done for the early detection of microbial growth to minimize the contamination.

Fuel System Maintenance

In maintenance, the exposure of the fuel to the water is minimized. Stabilizing fuel temperature, fuel tank insulation, discharging water bottom to prevent microbial growth and recycling fuel through water separations are the common procedures involved in the fuel system maintenance. In case it is too late and sludge has already been developed, it should be removed immediately.

Fuel Treatment

Treatment of the bottom of the tank is the best way to control microbial growth in the tank and fuel contamination. You can make use of fuel biocide or microbial growth remover for removing sludge that has already been developed.

The possibility of microbial growth can be reduced by buying a tank that downgrades its growth. Liquid Containment and some other reputed manufacturers of fuel tanks provide tanks that are least prone to the microbial growth and fuel contamination.
