Use biocides to kill microbes
Diesel fuel is a common choice for powering large vehicles and machinery due to its high energy content and efficiency. However, it is susceptible to contamination by microbes, often referred to as "diesel algae" or "diesel bugs". This sludge-like substance can cause clogged filters, engine damage, and reduced engine efficiency.
To address this issue, one effective solution is to use biocides, which are chemical additives specifically designed to kill microbes in diesel fuel. These biocides work by penetrating the cell walls of the microbes, causing them to rupture and die. By using biocides, you can ensure that your fuel is free from microbial contamination and prevent the associated problems.
When choosing a biocide, it is important to consider factors such as the type of diesel fuel, the severity of contamination, and the specific type of microbes present. It is also crucial to follow the manufacturer's instructions for safe and effective use. One recommended practice is to add the biocide to the fuel in the tank and then fill the tank with more fuel to achieve the recommended concentration of biocide. Additionally, using a biomass dispersant chemical alongside the biocide can enhance its effectiveness by breaking up the biomass formations created by microbes.
It is worth noting that simply adding biocide without proper circulation may be less effective. The treated diesel and dead microbes can settle at the bottom of the tank, potentially plugging the fuel filters. Therefore, it is important to circulate the fuel to ensure the biocide blends completely and reaches all areas. Additionally, you may need to change the fuel filters more frequently to remove the dead microbes and prevent filter plugging.
By using biocides correctly and following recommended practices, you can effectively kill microbes in diesel fuel, maintain fuel quality, and prolong the life of your engine.

Remove water from the fuel
Water in diesel fuel can lead to algae blooms, so removing water is a crucial step in preventing algae growth. Water can enter your tank in various ways, such as rainwater, condensation, or leaks. Here are some methods to remove water from diesel fuel:
Fuel Additives
Fuel additives are an effective way to remove water from diesel fuel. There are two types of additives: demulsifiers and emulsifiers. Demulsifiers cause the water and fuel to separate, allowing your water separator to catch the water and prevent it from reaching the engine. Emulsifiers, on the other hand, cause the fuel and water to mix, which can be detrimental if your water separator is unable to capture the water before it enters the engine. Therefore, it is crucial to use a demulsifier additive to ensure effective water separation.
Fuel Filtration Systems
Fuel filtration systems utilize two methods to remove water. The first method employs a water separator that uses centrifugal force to separate water from the fuel. The second method uses filter media that captures water as the fuel flows through the system and back into the tank. While the second method is more expensive, it is the most effective approach for addressing serious water contamination, especially in bulk storage scenarios.
Fuel Polishing Systems
Fuel polishing systems are ideal for non-commercial or small-scale applications and can effectively filter heavily contaminated fuel. These systems circulate fuel out of the tank, filter it, and then return it to the tank. This process ensures that water and contaminants are removed, improving fuel quality.
Drain Water from the Tank
Manually draining accumulated water from the bottom of your tank is a crucial step in preventing algae growth. Regularly check for water buildup and drain it to create an unfavourable environment for algae.
Preventative Measures
While the above methods address water removal, prevention is always the best approach. Keep fuel levels high to minimize air space and reduce condensation. Seal tanks tightly and regularly inspect them for leaks or damage. Repair any issues promptly to prevent water ingress. Additionally, choose reputable fuel suppliers with a history of quality control, and ensure fuel delivery equipment is clean and well-maintained.

Regularly clean and maintain the fuel tank
To prevent the growth of algae blooms in diesel fuel, it is important to regularly clean and maintain your fuel tank. This involves several key steps and considerations:
Firstly, it is important to understand that algae thrive in environments where there is water, nutrients, and favourable environmental conditions. Dirty fuel tanks, introduced water sources like rainwater, and organic materials can contribute to algae growth. Therefore, it is crucial to keep the fuel tank clean and free from contaminants. Schedule periodic professional cleaning of your fuel tanks to remove any contaminants and prevent algae growth. Regularly inspect and clean your fuel storage tanks to remove accumulated water and organic matter. Most tanks have a drain plug at the bottom for this purpose.
Secondly, consider using a fuel polishing system. Professional fuel polishing services use specialised equipment to remove contaminants and algae from your fuel. These systems circulate fuel out of the tank, filter it, and then return it clean. This helps to maintain the quality of the fuel and prevent algae buildup.
Thirdly, maintain optimal environmental conditions by ensuring adequate tank ventilation to prevent moisture buildup. Wide temperature swings encourage condensation, creating pockets of moisture where algae can thrive. Therefore, it is important to maintain fuel storage temperatures below the threshold favourable for algae growth. Additionally, consider using a fuel stabilizer if your engine will be sitting idle for extended periods. Fuel stabilizers can help prevent the growth of bacteria and other microbial contamination.
Finally, choose high-quality diesel fuel that is less likely to contain contaminants and impurities. Using reputable fuel suppliers and monitoring fuel storage conditions can minimise the risk of contamination. Additionally, consider treating your fuel with diesel additives that remove water and help prevent algae growth.
By following these steps and maintaining a clean and well-maintained fuel tank, you can effectively prevent and manage algae blooms in your diesel fuel.
