In this episode, Erik Bjornstad explains the comprehensive process of fuel polishing. He covers when to polish fuel based on test results, particularly the ASTM water and sediment test. The episode details two main methods: inline and off-site polishing, with a focus on the sweep, treat, and circulate methodology.

Bjornstad provides specific guidance on chemical treatments, filtration systems, and the importance of proper timing and sequence. He emphasizes the need for multiple passes through the filtration system and proper documentation before and after samples.

What You'll Learn:

• How to determine when fuel polishing is necessary
• The difference between inline and off-site polishing
• The sweep, treat, and circulate methodology
• Proper chemical treatment timing and sequence
• Three-stage filtration system components
• How to calculate the required polishing duration
• Best practices for sampling and documentation

Ideas Worth Sharing:

Here are three notable quotes from the podcast episode:

• "The goal for fuel polishing is to remove contaminants and restore the fuel quality."
• "Different people do have different ways of doing this. There is no one true best way to do this."
• "Effective fuel polishing usually requires multiple turnovers of the entire fuel volume to get that thorough cleaning that you're looking for."
