What You'll Learn
Use fuel polishing to remove water, sediment, and microbial contamination
If you are looking to store diesel for a long period of time, fuel polishing is a special process that can be used to prevent contamination. Fuel polishing is a technical cleaning process that removes water, sediment, and microbial contamination from diesel fuel. It is an improved alternative to filtration, as it recirculates the fuel, removing impurities and reducing the chances of damage occurring to your generator.
Fuel polishing is a three-stage process that can be used to clean diesel fuel tanks with a capacity of 20 to 10,000 gallons. During the first stage, the fuel is filtered from the tank using a special process that incorporates filtration, centrifuges, and coalescers. Advanced filters capture suspended particles and water, which is then separated from the diesel using centrifugal force. Water-blocking filtration media can then absorb any residual water.
If microbial growth is detected, specific biocides are introduced early in the process to kill any living organisms. The clean fuel is then returned to the tank. This process ensures that bacteria contamination is dealt with, and that both free and emulsified water is extracted from the fuel flow.
It is important to note that not all companies offering fuel polishing services perform a complete job. Some only perform a partial filtration, which can lead to re-contamination. Therefore, it is important to ensure that the company you choose performs a thorough cleaning of your tank. Most industry experts agree that fuel polishing should be performed at least once a year.

Employ bulk filtration to prevent contamination
Diesel fuel contamination is a common issue that can cause significant damage to your engine and equipment. It is important to take preventative measures to avoid the costly repairs and downtime that may result from contaminated diesel fuel. Employing bulk filtration is a critical step in preventing contamination and maintaining the performance and longevity of your diesel engine.
Bulk filtration systems are designed to remove contaminants from diesel fuel before it enters your equipment. These systems can be sized for any application, ranging from small to large and complex setups. The key advantage of bulk filtration is that it stops contaminants from entering your engine, ensuring the fuel remains clean. This includes the removal of dirt, water, soft solids, and even microbial growth, all of which can cause significant issues if left unchecked.
The process of bulk filtration typically involves a two-step procedure. Firstly, solid particles and contaminants are mechanically removed through high-efficiency filtration. This step ensures that dirt, dust, and other solid impurities are eliminated. Secondly, the diesel fuel undergoes water separation, where any free water is removed. Water can cause extensive damage to your engine, so this step is crucial. Additionally, bacteria can be filtered out using high-efficiency filters or treated with biocides to prevent microbial growth.
By implementing bulk filtration, you not only protect your engine and equipment but also improve fuel efficiency. Contaminants can lead to increased fuel consumption as they disrupt the delicate balance of fuel injection in modern diesel engines. Furthermore, bulk filtration helps to maintain factory efficiency and emissions standards, reducing air pollution and improving the air quality surrounding your diesel engine.
It is important to note that not all filtration systems are created equal. Some companies offer partial filtration services, which may not adequately address existing sludge or microbial growth in fuel tanks. Therefore, it is essential to choose reputable filtration solutions, such as those offered by Donaldson and Schroeder Industries, to ensure effective contaminant removal and maintain the performance and longevity of your diesel engine.

One reputable provider of clean diesel kits is Donaldson, whose kits are easy to install on any fuel dispenser and come with everything needed to filter out contaminants. The kits are designed to ensure that the diesel fuel entering your vehicle's engine is clean and dry, which is crucial for optimal engine performance and durability.
The Donaldson clean diesel kits include components such as the T.R.A.P. (Thermally Reactive Advanced Protection) desiccant breathers with integrated high-efficiency air filtration. These breathers reduce the risk of moisture and contaminants entering the bulk storage tank, keeping the fluids clean and dry. Additionally, the Active Reservoir Vent (ARV) is another feature that helps maintain fuel cleanliness by blowing dry air over the fuel to reduce relative humidity and remove dissolved water.
By investing in a clean diesel kit, you can effectively manage the cleanliness of your diesel fuel, protecting your engine, and preventing issues such as microbial growth, rust, and corrosion caused by contaminated fuel. It is important to note that regular testing and maintenance of your fuel and tank are also recommended to promptly address any contamination issues.
Furthermore, fuel polishing is another method to consider for maintaining clean diesel fuel. This process involves removing water, sediment, and microbial contamination to prolong the life of the fuel and the tank. While it is an improved alternative to filtration, it is important to ensure that a comprehensive fuel polishing process is conducted to address existing sludge and prevent re-contamination.

Use biocide to kill microbes
The use of biocides is an effective way to kill microbes in diesel fuel and prevent their spread. Biocides are often poured directly into the fuel tank to control the growth of microorganisms, such as bacteria and fungi, which can cause fuel contamination and degradation.
When using a biocide, it is important to follow certain steps to ensure its effectiveness. Firstly, add a biocide to the fuel in the tank, and then fill the tank with more fuel to reach the recommended concentration of the biocide. For example, Bellicide recommends a concentration of 1 ounce per 40 gallons to kill existing microbial contamination. Additionally, circulation of the fuel is critical to ensure the biocide blends completely and reaches all areas where bacteria are present.
To enhance the effectiveness of the biocide, it is recommended to add a biomass dispersant chemical simultaneously. This dispersant will break up the biomass formations, allowing the biocide to penetrate and kill a higher number of microbes.
It is worth noting that biocides do not address the root cause of microbial contamination, which is often the presence of water in the fuel. As such, the repeated use of biocides may become ineffective over time, and they are not suitable for heavily contaminated fuel. Additionally, they leave behind dead organic matter that can clog fuel filters, so these filters may need to be changed more frequently.
For long-term diesel fuel storage, a fuel stabilizer or antioxidant can be used alongside the biocide to interrupt chemical reactions caused by water and air exposure and protect the fuel from breakdown.
