Why do companies use microbiological contamination testing kits?

Microbiological contamination in diesel fuel is a very common problem.

It occurs when certain species of bacteria, yeasts, and fungi survive in, grow and impact negatively diesel fuel systems. Regular testing can detect fuel contamination early, so the fuel can be treated, relatively inexpensively, before further mechanical or operations problems occur.

Microbiological contamination is also known as diesel bug or diesel algae, although technically it has nothing to do with algae itself.

Why is microbiological contamination a problem for diesel fuel users?

Microorganisms are ever-present around us, in the air and on surfaces.

The microbial species that can live in the harsh environment of fuel systems gain their nourishment from the fuel hydrocarbons and water present. Microbes can happily grow even if there are small amounts of water present.

Water can enter fuel systems in many ways. The main source is often condensation, which can enter the tank or the fuel supply chain at almost any point. Getting rid of this water is a very important part of effectively managing diesel fuel contamination, but it’s very difficult to eliminate all water.

Because it’s so hard to eliminate water, fuel owners need to constantly monitor and manage the risks of diesel fuel microbiological contamination.

Organisations that use diesel fuel can proactively monitor for diesel fuel contamination with a range of tests that are done in laboratories. In addition, there are a few on-site tests for diesel fuel contamination available.

What are the consequences of diesel fuel microbial contamination?

Diesel fuel contamination potentially affects anybody who uses, stores or distributes diesel fuel.

This includes those who use diesel fuel in a land or marine engines, or who use diesel to power generators. Left unchecked, microorganisms can develop biofilms and biomass, and produce acids, which can result in:

Blocked filters and injectors

Gauging problems (instruments giving the wrong readings)

Degradation of fuel components

Increased fuel usage

Mechanical problems

Engine malfunctions

Leaking tank structures

Corroded fuel systems

These problems cause serious operational issues, like delays or assets being taken out of operation. In addition, the fuel itself becomes unusable. For large companies that store or move thousands of litres of fuel, the costs can add up to millions.

An example of how microbial contamination affects backup power generators

Users and maintainers of backup power generators have problems caused by diesel fuel microbial contamination.

Some of the microbial burden may end up in the bottom of the tank, so the generator works during testing, as it is drawing fuel from top of the tank. However, upon refuelling, the biomass may be disturbed and thus clog up filters.

This issue can result in increased risk of the generator not working. If the generator doesn’t start, there can be serious repercussions—when backup generators are installed for a data farm or a hospital, it’s obviously vital that they start up.

How is fuel contamination dealt with at its different levels?

Ideally, you want to catch microbial contamination at its early stages of growth.

In early stages, an application of biocide may be enough to keep diesel fuel microbial contamination from causing more issues.

However, the application of biocides is costly and difficult from a health and safety viewpoint, and from an environmental one. In addition, biocide overuse may lead to resistant microbial species, resulting in ineffective treatment.

With heavy contamination, you may need to conduct tank cleaning and have the fuel reinstated. The latter procedure is done through a treatment called fuel polishing, which requires assistance from specialist companies. In some cases, the diesel fuel may be written off completely, which could be extremely expensive and cause serious disruption to your service and reputation.

In severe cases, the acids produced by the microbial metabolism may cause corrosion. This means there is the possibility for the tank or pipeline contents to spill onto the earth.

When this happens, you would risk not only losing the fuel, but also causing a serious environmental issue. You would almost certainly have to involve specialist environment cleaning companies, and in some cases government agencies involved in environmental pollution.

How do I prevent diesel fuel microbial contamination from becoming a problem?

It’s worth noting that microbes will almost always be present in fuel to some degree.

The important thing is to make sure they don’t reach dangerous levels and form corrosive acids. There are two keyways to do this, alongside making sure the tanks, vessels or equipment that holds the fuel is maintained regularly:

Regular water draining.

Even a single drop of water can help microbial contamination to grow quickly, so you should remove water from your fuel frequently.

Test your fuel for contamination.

Fuel tests can be done fairly easily, and the cost is insignificant compared with what a serious case of contamination would cost you.

It’s worth noting that you need to choose a testing method that reduces the risks of misleading results. If your test results falsely show that you have a contamination problem, you may spend a lot of money treating your fuel, tanks and pipelines when it isn’t necessary. This will be explained later.

What type of diesel microbial contamination tests are available?

In addition to conducting regular water draining, it’s important that you test for diesel fuel microbial contamination with diesel fuel test kits on a regular basis.

Contamination can expand relatively quickly, especially in more hot and humid climates or seasons. It’s therefore sensible to try and detect growth at its earliest stage, before it gets a chance to do damage.

Early stage symptoms of contamination can often be treated by relatively cheap and simple measures, whereas heavier contamination problems can be far more serious and costly.

There are 3 main types of diesel fuel microbial contamination tests that you could choose from:

CFU (colony forming units) tests use a fuel sample to grow any culturable microorganisms present in it, under suitable conditions for growth (e.g. using appropriate growth media and an incubator).

ATP (adenosine triphosphate) tests involve quantification of the total ATP present in the sample by measuring the light emitted as a result of an enzymatic (luciferase) reaction, which indirectly indicates microbial presence.

Immunoassay tests don’t test for the presence of all microbial species , but instead focus on the specific microbes that are known to cause damage to fuel systems.

Which diesel microbial contamination test should you use?

The right test will depend on how quickly you need results, as well as the equipment that is available to you.

01.

CFU growth tests

CFU growth tests that take 4 -10 days to get a result and need an incubator.

These are very common tests that are available globally from laboratories that test fuel.

Unlike some other methods, CFU tests do not specifically look for microbes that are dangerous to fuel systems. They test for the total microbial presence in a sample, so the result may include general microbes that do not pose an immediate risk to diesel fuel.

Laboratories may not be located near to where the fuel sample was taken, in which case the fuel has to be transported. Fuel is a hazardous good, so the costs of transporting it are high. In addition, transporting fuel offsite means increased chances of misleading test results. This is because microbes can enter the samples, multiply, enter a dormancy period or even die during the journey—meaning the fuel samples do not accurately reflect what’s in the tank.

02.

ATP testing

ATP testing takes minutes and can be conducted on-site.

However, it requires an expensive piece of equipment called a luminometer in order to conduct a test. The diesel fuel tester also requires a certain amount of training and experience to achieve reliable results.

Similar to CFU, ATP testing looks for total microbiological presence, not just the microbes that do damage in fuel systems. Because of this broad testing scope, misleading results are possible.

ATP testing is usually conducted at a different location to where the fuel is being stored or used. There is a risk of exogenous microorganisms or other living cells entering the sample during the sampling, handling or transport phases. This can lead to misleading results, where the obtained signal from living cells is not directly reflecting the actual number of microbes present in the tanks.

03.

Immunoassay tests

Immunoassay tests can be conducted on site in 10-15 minutes.

There are no special requirements or equipment, and testers only need minimal training. Accordingly, immunoassay tests are a particularly good option for testing in remote or offshore locations.

An immunoassay diesel fuel microbial contamination test kit only looks for microbes that are known to damage fuel systems. The major advantage is that immunoassay tests are very simple to run, and little can go wrong. Additionally, they are performed on-site, thus avoiding the costs, control measures and delays of transportation.
