Fuel Filtration Service

Your storage tanks may be home to unwanted guests!

Hydrocarbon Utilizing Microorganisms ("HUM" bugs) are air-or-water borne bacteria that contaminate fuel systems by entering through vents, standing water in sump bottoms or during product delivery. HUM Bugs can hurt your equipment Over time these microbes and other contaminants can cause frequent maintenance problems and equipment damage including:

• Clogged dispenser filters and frequent filter changes
• Dispenser equipment problems
• Fuel system downtime
• Customer vehicle performance problems
• Lost customers

Preventive Maintenance Fuel Filtration Service can eliminate harmful bugs from your system and keep them out through a preventative maintenance program.

Filter Process

An intake and a return hose are inserted into the tank. The intake hose is inserted near the pump where the majority of contaminates tend to accumulate. The submerged pump is occasionally removed from the UST for hose access. Fuel is then drawn up through the intake hose; both intake and return hoses are moved in the tank during filtration process. The initial filtering removes the heavy tank bottom contaminant and water before the system is placed on full flow circulation. Observation of the amount and types of contaminants being drawn into the system occurs through a clear section in the intake hose. Contaminated fuel is then passed up through as many as four separate filters, depending upon the type of contaminants encountered. The hose is then repositioned throughout the tank to ensure that all areas are clean and the fuel is free of contaminants. With high velocity, the clean fuel is returned to the tank through the return hose while the hose is moved to flush the contaminant toward the intake hose.

 

Before and After

Fuel samples of untreated tank (left) show high levels of microbial contamination and particulate matter which cause frequent filter changes and equipment damage

Samples taken after treatment by Fuel Filtration Service (right) show clean fuel with excellent clarity, relatively free of sediment and microbes.
