At Njord Filtration, we are able to offer fuel polishing services to our clients from all over Europe. In the main, there are two principle reasons for the contamination of fuel – particles which have worked their way into it and water contamination. Particles often vary in size and the water content can also vary widely, too. In order to overcome these two issues, a fuel polishing system is required. Fuel that has been filtered, or polished as it is properly known, gets rid of these particles. A well polished liquid fuel will have very few particles suspended in it which bigger than around ten microns. Particles which are larger than this can present a significant risk to an engine that runs on unpolished fuel and they can cause an increased amount of wear and tear to mechanisms even under moderate usage.
When it comes to water, many people think that so-called free water – the water which naturally separates from fuel – just needs to be syphoned off and there is no requirement for further action. However, this is not the case. The fuel polishing system at Njord Filtration takes matters to the next level by actually removing the water that remains suspended in the fuel. Many fuels which have been stored for a long time end up with water suspended in them. What's more, water that is suspended in a fuel is available to bacteria which means that they can multiply. Indeed, harmful bacteria can grow in a fuel storage tank over time, so long as water is available. For this reason alone, it is important to polish away as much water as possible. In order to do this, careful measurements are required. The degree of water that is found in water has to be measured in parts per million.
Contaminated fuel is polished via various filters using a pump, with higher pressures being applied for more rapid results. When large volumes of fuel need to be polished, powerful equipment is called for and this is where Njord Filtration can help.

Our solution
FUEL TEST
If there are problems with filters, injectors, pumps or diesel quality in general, it is advisable to take a bottom sample from the tank(s) and have it analysed. Sometime the diesel is so filthy that the conclusion is obvious: the diesel must be cleaned.
We offer a sampling and analysis service as well as sampling sets to take your own samples. These can also be sent to us for analysis, or can be tested for microorganisms with Liqui-Cult.
REMOVING CONTAMINATION
If contamination of the diesel with water, sediment and/or microorganisms is discovered, it is important to remove the contamination from the tank(s) and to bring the fuel back into optimal condition.
To this end we offer a tank and fuel cleaning service as well as the equipment to recondition the fuel yourself. If we clean the tank and fuel, before and after samples are taken to demonstrate the effect of service provided.
PREVENTIVE MEASURES
After the contamination has been removed, it is usually best to ensure that it cannot reoccur. With modern diesel, however, the chance of this is relatively high. There are a number of preventative measures, products and systems available for this. The choice for one of these is different for each situation, client and available budget.
We offer sampling services, complete fuel maintenance contracts and installation of preventative products and systems according to the KIWA BRL-K903-08 norm.
There are a number of options for the tanks as well as the engines/burners:
IN-LINE QUALITY MEASUREMENT
If so desired, the quality of the fuel with regard to water and sediment levels can be measured in-line in order to control the quality or to adjust the filtration system.
