What is bio contamination?

Have you ever changed a fuel filter and it looked black?

This is fuel contamination caused by microbes or ‘fuel bugs’. Microbes in fuel tanks can be devastating.

Several types of microbes live in hydroscopic fuels. The microbes use the mix of fuel and moisture found in the tanks to make ‘new bugs’, quickly forming a colony. This is easily observed as black slime or sludge and produces by-products, such as Carbon Dioxide and Organic Acids which, in addition to blocking the filter, causes corrosion in fuel tanks and systems.

These byproducts also cause the engine to lose power, smoke excessively and increase the fuel consumption, ultimately damaging more of the environment than we can afford. Getting around the problem until now could only be achieved through the use of hazardous and poisonous biocides, banned by several major Oil Companies because of the dangers with handling and storage.

Why Abuot Biofuels ?
Having tested a variety of biofuels we found the results are the same. The organisms that will contaminate biofuel is of a greater variety and include a higher level of anaerobic material which will be very expensive for the operator.

Anaerobic material, often called SRBs, produce sulphuric acid which in itself is corrosive but will, in the presence of a suitable catalyst, be converted into sulphuric acid which is extremely corrosive and destructive.

What are Microbes or 'Fuel Bugs' ?

Think of these microbes as minuscule machines that convert fuel into non-fuel products. If left unchecked and under the proper conditions, your tank will contain more byproducts than pure fuel. These bugs can produce so much slime because they contain enzymes. The enzymes cut, reshape and join molecules. Each enzyme performs a very specific step in converting a hydrocarbon molecule into either new cell components or metabolites

How do I know if theis is my problem ?

Here are a few methods you can use to determine if you have microbes.

  • Check the filters and filter housings first because the microbes that are flushed by the fuel tanks will be trapped here. Once they are trapped, they multiply and form the slime that plugs the filter.
  • If this slime smells yeasty or like rotten eggs, you have extremely heavy microbial contamination.
  • It is really crucial to get the fuel tested before it reaches this point so you can save money and avoid damage to injectors and other fuel system components.
  • When you remove the filter, drain the fluid from the housing into a glass jar or clear sample bottle. If you see water, invert-emulsion, large suspended particles, or it just looks suspicious, get the sample tested immediately.
  • If your results come back positive for microbes, it is advised that you take a sample from the bottom of your tank and check the results.
Why not use Biocides ?

Firstly it is extremely toxic and secondly it is a single treatment with published averages of 100ml per 60 liters of fuel. It is a known fact that the microbes will start growing again after just four weeks if it is not completely destroyed. Every time you fill up or top up you introduce new microbes starting the process all over.

Why can the fuel suppliers not fix the problem ?

To keep moisture out of fuel systems and storage units is impossible. But it is the level of contamination that needs to be controlled.

What makes Pure Fuel different ?

It not only disrupts the microbes growth cycle but also allow them to be flushed out; whereas biocides still require you to change all the filters and clean the whole system with more chemicals.

How does Pure Fule work ?

Pure Fuel™ is not a biocide; it does not kill the bug. It is a bio-control unit. It affects the living organism by disrupting its environment and breaking the biomass down into individual plasmolized cells of less than 1 micron in size. These pass through the fuel filter and burn up in the engine.

What about the fuel returned to this tank ?

The treated cells remain dormant and inactive for long periods. The time frame depends on the environmental conditions, but it is long enough for the for the cells to be consumed by the engine. The fuel tank is slowly cleaned up in the process.

How do you know the effectivenes of Pure Fule ?

A study has been caried out by the department of Ocean Sciences in the University of Wales at Anglesey UK. This proves the effectiveness of Pure Fuel™. The methodology of the test was devised by The School of Ocean Sciences in conjunction with Lloyds Register of Shipping Type Approval Department of Engineering Services, Reference TA/40397/67488/94REL.

Further test conducted by CABI on our behalf to study the effects on a circulation system concluded that microbes can be kept at controllable levels even if installed after severe contamination.

The experiment was devised to determine the effect on a magnetically protected filter compared with an unprotected one when circulated with microbiologically contaminated fuel.

The result was that the unprotected filter became an ideal environment for microbiological growth and the filter became blocked. The protected one remained unblocked. The filter life was increased by a factor of 10. The results were so impressive that the University submitted them to the leading journal in the field of biological contamination for publication. The article was accepted and was published in Volume 14(3) 1999 of BIOFOULING.

Is Pure Fuel cost effective ?

Yes! the continual use of expensive and toxic biocides and the associated hazards are eliminated.

Will the unit affect electronic engine components ?

No! The field is depleted after it moves about 80mm from the unit. In addition, the field is absorbed by adjacent ferrite materials.

Can Pure Fuel be used to protect fuel storage tanks ?

Yes! By periodically circulating the fuel through a Pure Fuel™ the microbial matter can be maintained in a controlled, dormant condition.

Can Pure Fuel be used with other fluid system ?

Yes! Most definitely.

Why does Pure Fuel reduce engine smoke emissions ?

Quite simply, the biological contamination is removed and fuel quality is improved. If the system is contaminated then as it becomes cleaner the combustion process improves, giving cleaner, faster and more complete combustion of the fuel injected into the combustion spaces.

Why should I fit a Pure Fuel to my engine or sytem ?

Well, it depends on the circumstances. If your system is biologically fouled the Pure Fuel™™ will deal with the contamination, clean the system up and keep it clean.
If your system is not contaminated, then the aim is to keep it that way. You never know when you are likely to receive contaminated fuel.

Think of it in terms of your computer. Why do you install a virus protection program?

  • To deal with any existing virus contamination.
  • To protect your files from any virus that gets down loaded from an external source. The same principle applies with the installation of Pure Fuel™.
  • To deal with existing contamination.
  • To prevent any introduced bug from making a comfortable home for itself and degrading your engine system.
Where in the system should I install Pure Fuel ?

Pure Fuel™ breaks down the microbiological contamination to minute components so that it will pass through the filters into the engine and away in the exhaust. So the obvious place to install the Pure Fuel™ is in the fuel supply line between the talk and the fuel filter, this cleans the fuel before it enters any filtration or treatment unit.
