What does "fuel scrubbing" refer to?

Fuel scrubbing refers to the process of removing contaminants from fuel. This is a critical operation in ensuring that the fuel being used in aircraft is clean and free from impurities that could affect engine performance and safety. Contaminants can include water, dirt, microbial growth, and other particulates that might have entered the fuel during storage or handling.

By scrubbing the fuel, operators increase the reliability of the fuel system and reduce the risk of engine failure caused by fouled or contaminated fuel. This process might involve various filtration techniques and chemical treatments designed to ensure that the fuel meets the required quality standards before it is used in aviation applications.

Understanding fuel scrubbing is important in the broader context of fuel management in aviation, as it helps maintain fuel purity and compliance with industry regulations.
