140:. This fuel contamination, also known as 'fuel bugs', or 'diesel bugs', or 'so-called algae' build up over time in stored fuels if they aren't tested and treated on a regular basis. Fuel analysis should be undertaken before fuel polishing is commenced so that the exact contamination problem can be rectified with a targeted solution. A second fuel test should be performed after the fuel polishing has been completed to confirm the problem has been fixed.

Almost everything on Earth contains elements of water; oil and fuel are no exceptions. While very small amounts exist in fuels to start with, stored fuel will become a breeding ground for the microbial bacteria and over time, the levels of damage change from dissolved to emulsified and finally free.
231:, an aircraft carrying over 300 passengers, had a close call when fuel contaminated with spherical particles damaged the aircraft's engines, resulting in 57 passenger injuries as the pilots had to land the aircraft at twice the normal landing speed.

Diesel bug (microbial infections) can and often has the appearance of sludge. To the layman this could simply be dirt and sand, but is in fact a living organism. This sample was incubated over three months in a 1-litre jar of clean

These types of contamination can be introduced from many different sources throughout the supply chain of the diesel fuel as well as within the storage tank itself. Any one of these contaminants can cause complete engine failure.

is the technical cleaning process used to remove or filter microbial contamination from oil and hydrocarbon fuel in storage. It is essentially the removal of water, sediment and
287:- The most developed stage of fuel contamination is when free-flowing puddles of water appear within stored oil. At this point, bacterial contamination and growth is boosted.

275:- Dissolved water in oil is the presence of water but, unnoticeable to the eye. The water continues to develop until saturation point where water visibility begins.

281:- At the point of saturation, a cloudy appearance will be the tell-tale sign that the water/oil mixture has become emulsified.
