General Tank Cleaning Procedure
The MTC-X has two different operating modes, 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 Port 1 and exits through Port 2 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-X 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.
AFC Fuel Additive
The use of AXI International AFC-705/710 Fuel Additive is an essential part of any tank cleaning and fuel polishing procedure,
as AFC can more rapidly and efficiently decontaminate and clean the entire fuel system.
The additive is best introduced into the process after Fine Filtration Mode. Before dosing the tank with AFC-705/710,
remove as much of the sludge and free water as possible.
Adding AFC-705/710 to the tank will speed up the cleaning process by breaking down and dissolving the sludge covering
the tank walls and bottom. AFC-705/710 will decontaminate areas and sections of the tank that are out of reach of the
suction hose.
It is recommended to use a higher concentration of one to twenty five hundred (1:2500) instead of one to five thousand
(1:5000) for the first treatment. This has proven to be very helpful in accelerating the rate of dissolving sludge. Higher doses
may be necessary, depending on contamination level of the fuel.
AFC-705/710 is a full spectrum fuel additive, containing a combustion catalyst, surfactant (705), detergent, dispersant,
corrosion inhibitor, lubricity enhancers, and a fuel stabilizer that eliminates the need for expensive, toxic biocides.
