Fuel Analysis and Polishing at Medical Center

Fuel Analysis and Polishing at Medical Center

CommTank provided fuel analysis, filtration and polishing services for a 15,000 gallon underground storage tank (UST) and a 4,000 gallon generator belly tank at this Massachusetts based medical center.

Fuel Analysis

Fuel samples were collected by a CommTank technician from the 15,000-gallon underground storage tank and the 4,000-gallon generator belly tank. The 15,000-gallon UST sample showed mild microbial growth (1,000 CFU/ml) after 5 days of incubation, and borderline particulate. The flash point was within acceptable limits. The 4,000-gallon generator belly tank showed borderline particulate. The flash point was within acceptable limits. We recommended that the fuel in both tanks should be filtered and polished to remove major contaminants and antimicrobial treatment for the UST, as a preventative measure against further contamination.

In-Service Fuel Filtration and Polishing (each tank)

  • Collected a pre-filtration composite sample of fuel (top, middle, and bottom)
  • Filtered fuel with mobile particulate filtration system, capable of removing particulate to a level of one to five microns.
  • Polished circulating fuel at a rate of up to 60 gallons per minute.
  • During polishing process, removed all moisture/water content in fuel.
  • Upon completion, collected confirmatory composite fuel sample and screen sample following the ASTM D4176 Standard.
  • Placed generated waste into properly labeled steel 17H drums.
  • Transported and disposed profiled waste at a licensed recycling facility.
  • Added algae microbial treatment to the 15,000-gallon UST
