BACTERIA
Utilize
hydrocarbons and reproduce 'asexually' by binary fission;
swelling in size as they feed, they then separate into two
cells. In this way microbes double their numbers every 20
minutes, one spore becomes 262,144 in 6 hours. Typical
bacteria known to utilise hydrocarbons are Pseudomonas
aeruginosa, other Pseudomonas species, Flavobacterium spp.,
Acinetobacter spp., Alcaligenes spp., Micrococcus spp.,
Arthobacter spp., Corynebacterium spp., Brevibacterium spp.,
Klebsiella app.
SULPHATE REDUCING BACTERIA (SRB)
Are a specific
group of bacteria utilizing simple carbon, not hydrocarbons, and
require the activity of other microbes in a consortium. SRB
produce hydrogen sulphide. SRB are also directly involved with
many microbial corrosion reactions and can cause sulphide
souring of stored distillate products.
SRB's reduce sulphates and produce hydrogen sulphide (a lethal gas). They are directly involved with many microbial corrosion reactions and can cause sulphide souring of stored distillate products. Their action changes the Ph creating an acidic environment, conducive to accelerated corrosion. They attach themselves to the steel as a film and go to work. They derive their nutrition from the surrounding environment and multiply. They are particularly difficult to deal with and produce a sludgy by-product with a strong sulphur odour similar to rotten eggs (hydrogen sulphide).
IRON REDUCING BACTERIA
Contribute to corrosion, eating steel and reducing ferrite to
an oxide through a chemical reaction
YEAST
Bud
onto the parent cell, then eventually separate. Reproduction
takes several hours and yeast prefer acidy environments. Typical
yeasts growing on hydrocarbons are Candida spp., Saccharomyces
spp., Torula spp., Torulopsis spp., Hansenula spp.
FUNGUS
Grow in
the form of branched hyphae, a few microns in diameter, forming
thick, tough, intertwined mycelial mats at fuel/water
interfaces. Typical moulds which degrade hydrocarbons are
Penicillium spp., Aspergillus spp., Fusarium spp., Monilia spp.,
Botrytis spp, Cunninghammella spp., Scopulariopsis spp.,
Cladisporium resinae, Hormonicus resinae.
CAUSING
Restricted fuel flow, uneven atomization and
incomplete combustion caused by slime build up in the fuel lines,
filters and injector needles. Cylinders
develop cool spots causing uneven
wear to the rings and cylinder bores. Acids and gums can eventually
leach into the lubricating oil, causing corrosion of the crank
components. Some species of diesel bug create acids
that remove ions from the atomic structure of metals: this is the main
cause of corrosion in fuel tanks, lines, pumps and injectors.
-
Frequent filter blockages,
-
Loss of power &
torque,
-
Increase
fuel burn,
-
Increase
maintenance filters, fuel pumps and injectors,
-
Increase exhaust
smoke,
-
Increase equipment running
costs,
-
Decrease reliability,
-
Decrease service life of all fuel system
components
De-Bug Units
eliminate and
prevent
diesel bugs from occurring - fit once, run the engine or recirculation pump
regularly - That's it!
No filters to
change, maintenance is occasional draining. No chemicals, No bug
sludge forming in tanks.
By fitting a De-Bug Clean Fuel Unit
you will enjoy
Simply
by running the engine or a recirculation pump, the fuel is kept
clean and fresh.
