If black, brown or isolated white slime can be seen in the filter, you have confirmation that bacteria are already present in your tank as cohesive structures. If they are small, individual crumbs, this is usually not an indication of bacterial infestation. In individual cases, it is dead microorganisms and bacteria.

With the addition of currently seven percent biodiesel, a higher water content in the diesel can be achieved, as water and diesel separate more slowly. This increases the likelihood of contamination by bacteria in the tank. A few microorganisms are thus transported into the filter, which in turn becomes moist and provides a favorable habitat for the bacteria.
However, spontaneous filter clogging does not necessarily have anything to do with dirt in the tank.

Regardless of the causes, it is necessary to look directly into the tank by means of an opening. For this purpose, MFT Mikrofiltertechnik GmbH from Hamburg carries out so-called camera inspection. A small camera is guided into the tank and delivers images to a mobile device. On this you can see whether the bacteria have already deposited at the bottom of the tank.

More information about the Tank inspection can be found on our website or contact the people at MFT Mikrofiltertechnik GmbH in Geesthacht near Hamburg.

You can also test diesel fuel simply and reliably with mikrocount® fuel. You can find the product in the online-store of MFT Mikrofiltertechnik GmbH near Hamburg.
