Bulk Diesel


Why Does Bulk Diesel Fuel Need Filtration?


Modern diesel engines require clean fuel to operate reliably and efficiently. That cleanliness starts with fuel storage.

Effective bulk diesel fuel filtration helps remove contamination before fuel reaches the equipment. Cleaner stored fuel can reduce unplanned downtime, lower repair costs, improve fuel-system reliability, and help engines maintain expected performance and emissions over time.


Schroeder Industries offers a comprehensive arsenal of bulk fuel filtration solutions to maintain fuel quality and protect downstream filtration and components including:

How clean should my stored diesel fuel be?


Guidelines for bulk diesel cleanliness are outlined in the Worldwide Fuel Charter.

The Worldwide Fuel Charter (WWFC) is a series of guidelines developed by automotive and fuel manufacturers to create a global standard of fuel quality. Currently, the WWFC defines the ISO Target for bulk fuel cleanliness as 18/16/13.

Why is maintaining bulk diesel cleanliness important?


Diesel should be filtered at all stages, from storage to transfer as well as onboard. By ensuring a minimum cleanliness standard for bulk diesel, downstream filtration is less likely to be overwhelmed by high contamination loads.

 

Bulk Storage

Below are microscopic comparisons of a common condition of bulk diesel tanks versus the WWFC target of ISO 18/16/13.


If you need to reach <12/9/6 to protect your injectors, which bulk fuel condition would you rather start with?

What are the signs of water contamination in my bulk diesel fuel?


  • Microbial colonies known as ‘diesel bug’ can grow and thrive on the border of diesel and free water, forming clumps and mats of organic matter.
  • Rapid filter fouling during filtration or transfer may be a sign that diesel bug is abundant in the stored fuel.
  • Cloudy or hazy fuel samples are often a sign of emulsified water and/or microbial growth.
  • In highly saturated fuel, a layer of visible water (‘free’ water) can separate from the diesel.
Contamination

How does bulk diesel fuel become contaminated?


  • New fuel does not always meet the WWFC bulk storage standard! Fuel can be contaminated as it moves through the supply chain. Be sure to filter any newly purchased fuel before adding to storage.
  • Storage tanks may already be contaminated. Clean your empty storage tanks before adding new fuel.
  • Storage tanks are vulnerable to environmental contaminants. Storage tanks, especially when kept outside, are vulnerable to rain and humidity, pollen and dust, and other environmental factors.
  • Microbial growth can worsen contamination. When diesel becomes contaminated with water, microbial growth called ‘diesel bug’ can proliferate. Even if killed through fungicidal treatments, organic matter from the diesel bug can foul filters and damage components.

Preventing contamination requires a multi-faceted approach:

  • Ensure that any potential points of entry for contaminants are either sealed or utilize breathers to capture airborne particulates and humidity before it can enter the tanks.
  • When adding new fuel to the tanks, use transfer filtration to prevent the introduction of potentially contaminated fuel into the storage system.
  • Monitor and manage fuel condition through regular testing, filtration, and polishing.
