Water contamination in diesel fuel is a critical issue that can cause significant damage to engine performance and fuel quality. Water can enter the engine through condensation or external environmental factors, and it is important to remove it as soon as possible as diesel and water do not mix. There are various methods to remove water from diesel fuel, including using a demulsifier, a water eliminator, or a high-quality filtration system. Additionally, certain additives can be used to absorb water back into the fuel, and it is important to regularly check and maintain diesel tanks to prevent water contamination.

Filtration systems
Water contamination in diesel fuel is a critical issue that can lead to engine damage, reduced performance, and increased maintenance costs. To mitigate these issues, various filtration systems have been developed to remove water from diesel fuel and ensure optimal engine operation.
One commonly used filtration system is the fuel water separator, which is designed to remove water and contaminants from diesel fuel before it reaches the engine. These separators typically utilise a 10-micron fuel filter to capture over 99% of particulates and act as a barrier to water in the fuel. As water is denser than diesel, it sinks to the bottom of the separator, allowing for effective water removal. Fuel water separators are simple, inexpensive, and easy to maintain, making them a popular choice for boat and vehicle owners.
Another type of filtration system is the coalescing filter, which uses specialised media to merge tiny water droplets into larger ones, facilitating easier separation from the fuel. Coalescing filtration systems are often used in conjunction with water separation systems to enhance overall filtration performance. Advanced coalescing technologies are being developed to improve water separation efficiency and prevent issues like injector fouling and microbial growth.
Single-stage filtration systems, consisting of a single filter element, are typically used in simpler applications where basic filtration is sufficient. They are easy to install and maintain but may not offer the same efficiency as multi-stage systems. Multi-stage filtration systems, on the other hand, employ multiple filter elements arranged in series or parallel to capture different sizes of contaminants. These systems are designed to remove both particulate and water contamination, ensuring optimum engine performance and reliability.
Water eliminators, such as the WE-12 Water Eliminator®, offer an easy and economical solution for removing water from diesel fuel storage tanks. It features a cylindrical design with a nylon "skeleton" and a filter screen containing absorptive crystals. These crystals absorb water, and the unique design ensures that the shape is retained even after reaching its full capacity, making removal from the tank opening convenient.
Investing in a top-tier filtration system is crucial to protect engines from the adverse effects of water-contaminated diesel fuel. Regular maintenance of these systems is also essential to preserve their effectiveness in removing water and contaminants, ensuring efficient and reliable engine operation.

Demulsifiers
Water in diesel fuel is a serious issue for diesel equipment owners and operators. It can cause significant damage to fuel quality and engine performance, and in small systems, it can freeze, causing operational issues. Water is also the habitat for microbial and fungal contamination, which can cause filters to clog and engines to smoke.
To address this problem, various methods and products are available, including emulsifiers and demulsifiers. Emulsifiers work by combining water with fuel, creating a homogeneous mixture where water passes harmlessly through the fuel delivery system and is vaporized in the combustion chambers. However, some argue that emulsified water can come out of suspension and cause problems.
One such demulsifier product is the Water Eliminator®, which offers an easy and economical solution for removing water from fuel storage tanks. It utilizes a cylindrical injection-molded nylon structure with ultrasonically welded ribs surrounding a filter screen containing absorptive crystals.
Another approach to removing water from diesel fuel is through filtration systems, such as the AirDog® FPII system, which passes the fuel through a water separator before sending it to a particulate filter. This helps maintain the efficiency and longevity of the engine by effectively separating water from the fuel.

Emulsifiers
Additionally, emulsifiers have surfactant properties, which reduce the surface tension between the unlike molecules of oil and water, further enhancing the homogeneity of the mixture. This process is known as emulsification, and it helps to keep the water droplets suspended in the diesel fuel.
While emulsifiers can be effective in managing water contamination in diesel fuel, it is important to consider the potential drawbacks. One concern is the loss of lubricity, which can damage the fuel pump. Furthermore, in diesel engines, the high pressures at the injector tips can turn the water into steam with enough force to explode the injector tip, leading to costly repairs.
As a result, while emulsifiers can be useful in certain applications, such as gasoline engines, demulsifiers are generally recommended for diesel engines. Demulsifiers cause water to separate from the fuel, allowing for easier mechanical removal through techniques like draining or filtering. Therefore, while emulsifiers play a role in water management, demulsifiers are often considered the preferred option for diesel fuel water control.

Water Eliminator
Water in diesel fuel can cause significant damage to fuel quality and engine performance. Water contamination is a critical issue as diesel fuel attracts and absorbs moisture from the air at the molecular level, so it almost always contains some water. The key is to minimize the water level and filter out any remaining water to maximize fuel efficiency and protect your engine.
The Water Eliminator is a cost-effective way to remove water from diesel fuel storage tanks. It is placed in the fuel tank, where its absorptive crystals absorb water, protecting your engine and preventing fuel deterioration and microbial/fungal growth. The WE-12 Water Eliminator has a cylindrical injection-molded nylon "skeleton" with several longitudinal and circumferential ribs that are ultrasonically welded and surround a filter screen that contains the absorptive crystals. This construction retains its shape after the crystals have absorbed their full capacity of water. It will not deform or impede removal from the tank opening.
The WE-12 Water Eliminator is 12 inches long and requires a 1.85-inch or greater tank opening. It works in tank depths of up to 2 meters. It is ideal for use in marine applications, construction, farming, and off-road applications where the fuel tank experiences considerable movement. It can also be used in larger tanks by stringing several WE-12 units together in a "daisy chain" arrangement.
It is important to note that the Water Eliminator unit is not designed to be withdrawn around bends. It must lie flat on the bottom of the tank, with a rod inside providing weight and ensuring that the unit stays at the bottom. For optimal results, it is recommended not to use additives containing water dispersants when using the Water Eliminator. The insert should be removed from the tank in less than 60 days.

Water separators
Water in diesel fuel can cause significant damage to fuel quality and engine performance. Water contamination became a critical issue after the adoption of ultra-low sulfur diesel, which attracts more water and is less resistant to microbial growth. Modern diesel fuel systems are also less forgiving of water in the fuel, so it is crucial to minimise the opportunity for water to enter a truck's fuel tank and to keep any water that does enter the tank from reaching the engine.
When choosing a water separator, there are a few factors to consider, including the filter's filtration rating, the type of collection bowl, and your engine's fuel consumption rate. The size of the water separator should generally correspond to the size of your engine.
One example of a water separator is the AirDog® FPII system, which passes the fuel through a water separator before sending it to a particulate filter. AirDog® has also introduced a new generation water separator, the PureFlow™ Technologies WS200-HS Water Separator/Pre-Filter, to maximise the system's overall performance.
