Fuel Polishing is defined as the removal of water, sediment, non-combustible particulate matter and microbial contamination below levels stated in ASTM D975 (Standard Specification for Diesel Fuel Oils) while resuspending combustible particulate matter to maintain ASTM standards for BTU value, lubricity, and cetane.
Fuel polishing uses centrifuges, coalescers, and filters to remove non-combustible particulate matter (sand, dust, and other contaminants) from fuel.
