The Importance of a Water Separator in Diesel Fuel Polishing: Expert Advice

As you may already know, diesel is the heartbeat of every power system, especially in more significant industries like offshore marines, oil industries, etc. These big industries cannot compromise with either contaminated diesel or loss of power, considering this can lead to great damage and loss to the industry financially. This is why, in every big and small industry, one will always find a portable diesel fuel polisher for generators. These polishers ensure the fuel is dust and debris-free and enhance its overall quality for better and faster results. 

But did you know that the water separator is the most essential part of a fuel polisher? It is no secret that despite oil and water not mixing well, water can, in offshore or extremely humid regions, mostly get inside the polisher and damage the overall quality of the fuel. 

In today’s blog, we will discuss the importance of a water separator and the difference it can make. Keep reading about it with Njord Filtration.

But first…

What is a Water Separator in a Diesel Fuel Polisher?

Water can quickly degrade the quality of diesel fuel due to many underlying reasons, including humidity, poor fuel storage, condensation, etc. This will not only damage the fuel's potential but also cause serious engine problems, resulting in frequent blackouts in the industry. A water separator, in this case, ensures that the water is removed from the fuel, enhancing its overall quality.

Let us explain how a water separator can help the industrial diesel fuel polisher machine work more effectively. So, technically, a water separator ensures that:

1. It sits nicely in the fuel polishing machine, and as the fuel flows, the separator detects and traps the water. 
2. During this process, the water settles at the bottom while the fuel continues to undergo the next stage of filtration. 
3. Once the water is successfully separated, the drain valve attached to the separator automatically drains it.

The importance of the Water Separator

As you already know, water and fuel do not mix well. If you do not clean the fuel and keep it free from moisture and water, it can result in system damage, frequent breakdowns, engine failures, or microbial growth that can cause permanent damage to the machinery.

The reason why the water separator plays an important role here is that:

• Water separators prevent microbial growth, ensuring there is no growing space for fuel-eating microbes. 
• When the fuel is 100% water-free, it burns more efficiently, resulting in improved power output. 
• Water-separating units ensure the fuel is clean and dry, which in turn prevents rust in the pumps, injectors, and filters. 
• One of the most important factors is that water separators ensure the fuel quality is up to the mark so that emergency breakdowns can be avoided, especially in boats, yachts, etc.

Key benefits of using a Water Separator

When industries go for a diesel fuel polisher with water separator, they get direct benefits like:

• Eliminating water before it reaches the engine. 
• Increases the lifeline of the fuel.

How to Maintain Fuel Cleanliness in Biofuel Tanks with Njord Mobile Tank Cleaning Systems?

If you didn’t know, biodiesel is made through a chemical process that turns fats or oils into fatty acid methyl esters, also known as FAME. This process is known as transesterification, and it creates fuel that is free of all impurities while meeting strict quality requirements. Even though biofuel has many benefits, you still need to handle and store it in specific conditions.

You can use this renewable and clean-burning alternative in diesel engines without altering it. However, you need to manage it properly to maintain its quality and effectiveness. This blog will discuss how you can maintain fuel cleanliness in biofuel tanks.

How Can You Maintain Fuel Cleanliness in Biofuel Tanks?

• Cleanliness: You must clean the biodiesel storage tanks regularly to prevent sediments, microbial growth, and other contaminants from rapidly accumulating over time. Finally, ensure tanks are thoroughly dried after cleaning and refilling. Routine clean-up can help you maintain the purity and quality of fuel while preventing potential clogging.

• Filtration: You need to install a filtration system like Njord Mobile Tank to remove particulate matter and water from biodiesel during storage and transfer. A filtration system will help you filter contaminants to prevent contamination and deterioration. Also, don’t forget to keep an eye on the filter and replace it regularly to maintain fuel quality.

• Inspection: You should inspect biodiesel storage tanks regularly to find signs of leakage, corrosion, and contamination. During inspections, you can check for any visible damage or wear and tear and also look for unusual odours or discolouration. This way, you can address any issues that require your attention before they can cause any big trouble.

What Factors Affect Biodiesel Storage?

A lot of factors can affect your biofuel, even when you are only storing it. Here are some of the main reasons:

• Storage Temperature: Since biodiesel has a greater cloud point which means that it gels at a higher temperature. Hence, you need to store the biodiesel at a higher cloud point, especially if you are in a cold region. You can store it at an ideal temperature range of 4 to 21 degrees Celsius.

• Tank Material: When storing the biodiesel, make sure that the tank is made up of appropriate materials to avoid any unnecessary reactions. Materials include fibreglass, aluminium, fluorinated polyethene, and stainless steel. The materials that react with the biodiesel or can contaminate it include uncoated mild steel, copper, brass, tin, lead and zinc.

• Water Contamination: One of the main contaminants of biodiesel is water, which can result in fuel deterioration and clogged filters due to microbial growth. Hence, you need to use watertight tanks to store biodiesel so it can reduce the amount of water contamination. You can also regularly inspect and drain water from tanks and cover tank vents to keep the moisture out.

• Light and Oxygen: If your biodiesel gets exposed to light and oxygen, the oxidation process will accelerate. This will lead to the formation of acids and sediments. So, when you store biodiesel, make sure that the tank is sealed and opaque to reduce the exposure to these elements.

Why are Fuel Polishing Services for Emergencies so Important?

In today’s rapidly evolving industries, uninterrupted power is essential. Emergency generators play a vital role, but only when fueled with clean, reliable diesel."

This process significantly improves fuel reliability as with time, diesel fuel can degrade, get contaminated or in the worst case, form sludge. That’s where Njord Filtration’s fuel polishing services for emergency generators come in.

But what is it?

As we mentioned earlier, fuel polishing is a process that cleans and enhances the stored diesel fuel’s original quality by removing water, sludge, microbes, and solid contaminants. This is important when diesel is stored for long periods, especially for backup generators that are not used daily, and it works pretty well.

During this process, Fuel is first pumped from the tank into a polishing unit. Then, it passes through multi-stage filters that remove water, sediments, and other fuel-eating microbes. In the third stage, the clean fuel returns to the tank, ready to power your emergency generator when needed. But that’s not all. 

There are so many technical benefits you need to know about. In today’s blog, we will cover why fuel polishing is vital for emergency generators and which industries must definitely opt for it, especially in 2025.

How Regular Diesel Filtration Protects Your Yacht Engine from Contamination

If you own a yacht, you must know how important it is to filter the diesel regularly to protect your yacht’s engine from contamination. Filtering diesel guarantees that the engine receives clean and dry fuel to maintain high-performance levels. If you are not aware, then today is your lucky day! In this blog, we will discuss the importance of regular diesel filtration in yachts.

What is Fuel Contamination in Diesel Engines?

Fuel contamination is an issue that has existed for ages; it is not new. Despite all the improvements in refinement technology and better fuel regulations, you need filtration. The contamination is caused by common contaminants, such as dust, rust, microscopic particles, and even water. These can enter the fuel supply at any point during production, storage, and transportation. To you, they may seem insignificant, but these particles can have the potential to harm your yacht’s engine seriously.

Fuel systems have to maintain an extremely tight tolerance while operating at high pressure. The operation has to run with precision, and fuel pumps and injectors need to guarantee that the appropriate quantity is supplied at the appropriate moments. These contaminants can, however, cause abrasion, clogging, and damage, resulting in engine failures. In general, even water can cause corrosion in the fuel system and result in injector failure. Hence, having a diesel filtration system is necessary to do periodic filtration.

How is Diesel Filtration Important to Protect Your Yacht’s Engine?

The fuel filtration acts as the first line of defense to protect your yacht’s engine against dangerous impurities. They keep the moisture and particulates out of the engine’s fuel injection system. This essentially preserves the functionality and health of the engine. Let’s have a look at what else fuel filtration does to provide protection:

• Engine Performance: The quality of your yacht’s fuel system directly affects its engine performance. A clean and effective fuel system can enhance engine performance, while vice versa can degrade it. This is because the fuel contaminants can lower the combustion efficiency and result in poor acceleration or power loss. However, when cleaner fuel is delivered through a filtration system, it can improve fuel economy, power output, and engine smoothness.

• Fuel Pumps: High-pressure pumps are necessary to deliver the fuel to the injectors in the fuel system. However, any impurities that get inside the fuel pump can have the potential to harm its parts, which could result in pressure loss or eventual failure. If you have a high-quality fuel filter, it can help keep the dangerous particles out of the fuel pump to maintain optimal performance.

• Injector Deterioration: Fuel filtration can help you prevent wear and tear in the injectors. These fuel injectors are engineered to atomize fuel for the best possible combustion. However, contaminated fuel can wear them down or abrasively damage these sensitive injectors while flowing through. This will eventually result in poor fuel atomization while decreasing both fuel efficiency and power output. In other words, high-quality fuel filtration can extend the life of the injectors by keeping these abrasive particles from getting to them.

• Overfueling: In certain engines, contamination can cause even fuel flow, which can cause overfueling. This can lead to increased fuel consumption, poor combustion, and elevated exhaust emissions. However, a consistent fuel supply through a dependable fuel filter can help you maintain the ideal air-fuel ratio for proper combustion.

• Emission: If your yacht’s engine has poor combustion due to contaminated fuel, it can release two hazardous gases: Nitrogen Oxides (NOx) and particulate matter (PM). This puts your yacht at risk of failing emission testing and negatively impacting the environment. Hence, a filtration system can ensure that you have clean combustion to help diesel engines fulfill strict emission regulations while having less environmental impact.
