Preparations
Before operating the MTC, we recommend determining the amount of contaminants, free water, and sludge in the tank.
AXI International provides a variety of tank sampling equipment, including Sampling Pumps, tubing and bottles, as well as
Tank Samplers (“Bacon Bomb”) – please see our FS Fluid Sampling line of products. Please make sure the samples are
taken from the bottom of the tank (in the deepest spot). Use a stick with “Kolor Kut” paste on the end, reach through the top
of the tank, and place the end of the stick all the way at the bottom of the tank. Kolor Kut paste will show the water level in
the tank, and indicate how much water, and sludge, will have to be removed. Call AXI International for further information
on other fuel sampling equipment.
General Tank Cleaning Procedure
The MTC has two different operating modes (Bypass Mode and Fine Filtration Mode), providing the operator flexibility and
time efficiency.
In
Bypass Mode
, bulk water and sludge are removed from the tank into a separate container for disposal. The fuel bypasses
the fine filters, removing free water, sludge, and particulate, as small as 1 micron, from the tank. During this step, the system
is not in a re-circulating mode. The fuel enters through the Inlet Port and exits through Discharge Port 1 into a separate
waste container. Water and sludge are directly removed from the tank and collected in an appropriate container for disposal.
Next step, while still in bypass mode, put the hose that was in a separate container back into the main tank to create a kidney
loop. This process will further save and extend the life of the spin-on filters, and remove the worst of contaminants, before
polishing with fine filters to meet the required cleanliness.
In
Fine Filtration Mode
, the MTC system is continuously restoring, reconditioning, and returning the fuel back to the tank.
Fine Filtration mode will continuously remove free water and particles as small as 1 micron, utilizing high efficiency spin-on
filters.
We always recommend keeping a “before” and “after” bottom tank sample for “show & tell” purposes to demonstrate the
improvement of fuel color, clarity, and opacity.
