What does biofilm (sludge) look like?
![Page 6: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/6.jpg)
Biofilm can be Transparent
Filters appear similar
Far left is plugged
Second is partially plugged
Third is partially plugged
Fourth is operating fine
Each filter weighs less as you go from left to right (biofilm increases weight of filter)

Microbially influenced corrosion
![Page 11: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/11.jpg)
What is Fuel Right?
• Combination of powerful amine chemistries
• Alkaline chemistry
• Derived from water treatment industry
• Unique properties
![Page 12: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/12.jpg)
How does it work?
• Biofilms are held together by exopolysaccharides “glue”
• Resistant to biocides
• Fuel Right “melts” the glue
• Re-dispersed back into fuel microscopically
![Page 13: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/13.jpg)
Other Properties
• Dissolve gums
• Filming amine corrosion barrier
• Electrical Insulator (impedence)
• Water proof
• Natural Surfactant
• Alkaline (Stabilizer)
• Improves Lubricity
![Page 14: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/14.jpg)
MIC
Microbial influenced corrosion refers to the influence of microorganisms on the kinetics of the corrosion of metals, caused by microorganisms adhering to the interfaces (usually called “biofilms”). Prerequisites for MIC are the presence of microorganisms. If corrosion is influenced by their activity, further requirements are: (I) an energy source (II) a carbon source (III) an electron donor (IV) and electron acceptor and (V) water.
![Page 15: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/15.jpg)
MIC Process
Requires key elements
1. The existence of bacteria Naturally present in fuel
2. The presence of water / oxygen Present in fuel - typically delivered by fuel delivery company
Condensation / leaking / openings
3. A surface to attach to (biofilm) Tank walls
Tank linings (holidays)
Contaminants (oxides, salts etc.)
![Page 16: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/16.jpg)
Types of Organisms Present in Biofilm
Variety of bacteria present Aerobic – such as slime forming bacteria
Anaerobic – produce organic acids
Fungi – produce organic acids
Some have the ability to substitute oxygen with oxidisable compounds
ie: Iron (Fe), Manganese, Sulfur
![Page 17: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/17.jpg)
Anodic Sites – Pitting Corrosion
pH of “sludge” is acidic pH value varies across biofilm
Steel surface sacrifices electrons (becomes sacrificial anode)
Accelerated corrosion process (pitting) occurs in localized areas
Rate is dependent on biofilm colony
![Page 18: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/18.jpg)

MIC Affects Fuel Pumps
![Page 20: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/20.jpg)
How to STOP SLUDGE and MIC?
Eliminate bacteria? Biocides can kill bacteria but do not dissolve sludge
Biofilm (sludge) and biocides? Extremely resistant to attack, biocides are ineffective
Can not be “washed” from the surface Only sandblasting to near white metal finish will rid of existing bacteria
Water/Oxygen Control water but source is external
Steel Protective Coatings
Industrial coatings
Filming Amines
Coatings are prone to MIC
![Page 21: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/21.jpg)
Fuel Right Technology
FUEL RIGHT® - stand alone technology Proprietary formulation of filming amine technology
NOT a conventional diesel fuel additive
NOT a biocide
Release biofilm from steel surface and protect surface with filming amines
Existing sludge is dissolved by Fuel Right

What are Filming Amines?
Form a protective coating Waterproof barrier
Inhibit corrosion
Isolative (electrical impedence)
Penetrate the biofilm Impeding the growth and displace existing biofilms
Dissolving the sludge back into a microscopic form to be dispersed safely into fuel and burned off.
Clean and control downstream deposits in the fuel system Fuel injectors
Intake valves
Fuel pump
Filters

Fuel Right & Diesel Engines
Coats complete fuel system
Protects injectors against fouling
Ensures optimal atomization
Optimal ignition
Impacts fuel economy Keeping system clean ensures optimal fuel performance
Filming amines have a natural detergency affect
![Page 35: Fuel right and mic v21](https://reader033.vdocuments.site/reader033/viewer/2022042815/5568a6f4d8b42a4c378b4993/html5/thumbnails/35.jpg)
Implications
Higher tier engines have strict tolerances
Fuel quality is critical – especially in emergency supply situations where fuel is stored long-term
Fuel additives modify fuel properties (lubricity, cold flow pour point, cetane boost, anti-waxing & gelling) but do not “clean” the system
Filming amine technology protects the system from biofilm attack
Smaller micron filters are more prone to biofilm clogging
Fuel Right filming amines dissolve the biofilm – clean fuel
Overall better fuel system performance
