We assess fuel samples for visible water content and sediment, along with evidence of bacterial contamination.
If there is water present, it’s important to remove it. Water is the host environment for bacteria that eats fuel as food, and secretes acids which corrode tanks and fittings, eventually leading to a fuel breach.
After the water is removed, we use long semi-rigid hoses to sweep the bottom of the fuel tank, reaching all corners and spending additional time removing sediment underneath the critical areas of the tank.
Work up to this point is called our Water and Sediment Removal Service. The photo above shows a sample with some sediment and a little water, and is a great candidate for this level of service.
After that, we can continue to polish all of the fuel in the tank, if required, using our high-speed pumps to create turbulence in the fuel, suspending rust, sediment and dirt. This cleans almost every part of the tank, and removes particles suspended in the fuel, but of course, takes longer and cost more.
That’s not always required, though. We encourage fuel managers to do something, rather than nothing. If budgets don’t permit a full fuel polishing with dialysis, at least remove the Water and Sediment on the bottom of the tank, and apply biocide.
