What is the purpose of using a settling tank in fuel handling?

The purpose of using a settling tank in fuel handling is primarily to allow impurities to settle out of the fuel. Settling tanks are designed to provide a quiet environment where fuel can remain undisturbed for a certain period. During this time, heavier particles, such as dirt, sludge, and water, can naturally settle to the bottom due to gravity. This process is vital in maintaining the quality of fuel, ensuring that only clean fuel is transferred to storage or usage, ultimately leading to more efficient operation of fuel systems and engines. By removing these impurities, the risk of clogging filters, damaging components, and reducing fuel efficiency is significantly minimized.
