159 from Chemplex provides a bacteriostatic action that
controls the growth of bacteria (diesel bug). In bulk storage tanks,
the interface between
the fuel and water, which is a result of condensation, creates an
environment friendly to
bacteria development. Supertech 159 provides a dual action response
to this problem: Supertech 159 kills the
Supertech 159 picks up the water, thereby
eliminating the environment
that enables new bacterial growth. It generates an

performed in accordance with ASTM D-1744, 1% water was
added to two fuel samples. Chemplex Supertech 159 was added to only
one of the fuel
samples. Both were vigorously shaken and then allowed to rest for at
least one hour to
allow for separation of the fuel and water. Testing of the upper
layer in both samples
showed a 4% improvement. The fuel treated with Supertech 159 showed
and increase of 2 ppm
of water in the fuel samples, which shows the water was emulsified
in the fuel instead of
separating. Statistically, this is a significant reduction, and with
maintenance program, it will minimize the accumulation of water in
fuel storage tanks.
The trend in the petroleum industry is an
