How To Remove Algae From Diesel Fuel Tank?

It’s one thing to discover that your fuel contains algae. But getting rid of it and keeping it away is a very different story. If you don’t want a constant headache, you must win this game.

If you have the correct remedy, treating diesel fuel algae is rather straightforward. But what we truly mean by “easy” is “follow these few tips and you’ll have a good probability of resolving the problem.”

Get Rid Of The Water

This is the first stage in any endeavor to remove algae from the gasoline. Water is required for fuel microorganisms to survive and thrive. Drain the water out mechanically if you have more than half an inch of water (you should be measuring it with a tank stick and some water paste). After that, clean up the remaining with some form of water-absorbing chemical treatment. Everything else won’t work as well if you don’t get rid of the water first.

Apply A Biocide, Not Just A Generic “Water Treatment”

I know we just told you to use chemical treatment to clean up the rest of the water. That advice still holds true. However, the treatment isn’t meant to kill the bacteria; rather, it’s meant to improve the environment so that they can’t flourish in the water. No, you’ll need to kill the active microbial contamination in the tank with a specific biocide. Because fuel biocides kill active living organisms in any liquid they are employed in, they are tightly regulated and restricted. That’s a positive thing in this case. Something that will kill the fungus, mold, bacteria, and algae is ideal. Simply scavenging the water will not suffice.

Don’t Undertreat

When we speak with consumers, we advise them to use enough biocide to treat the maximum amount of fuel in the tank they’re considering, not simply the amount of fuel in it at the time.

Assume they have a 12,000 gallon fuel tank with 5,000 gallons of fuel. They will also fill the tank to a maximum of 10,000 gallons. The suggestion would be to add enough biocide to the 5,000 gallon tank to treat 10,000 gallons. That way, when they add gasoline later, they’ll have 10,000 gallons of fuel with just enough biocide to kill everything it comes into touch with.

Because there are usually latent bacteria residing on the tank walls above the gasoline line, this is critical. Using enough biocide to treat the maximum fuel level means that when more fuel is added, the fuel level rises and kills the microorganisms since the fuel contains enough biocide.

Circulate The Fuel To Ensure Best Mixing

This is quite significant. It’s not enough to simply dump biocide on top of current fuel and leave it alone, thinking that the biocide will diffuse down and do its job. The biocide will be injected into the fuel line by industrial bulk fuel users. Why? Because this is the only way to ensure that the biocide is properly mixed in. A biocide won’t work until it comes into actual touch with the organism it’s designed to kill. So, if you want the biocide to work, make sure it’s thoroughly mixed into the fuel. That’s fantastic if you have the technology to inject it into the gasoline line. For many clients, the biocide will be added after the gasoline has been circulated for a length of time. That also works quite nicely. Those are the four most significant suggestions.

Other suggestions include allowing time for the dead germs to settle after they’ve been killed. Also, have spare gasoline filters on hand to filter out any dead bacteria. You’ll have a far higher chance of solving the problem the first time if you follow these easy guidelines.

What causes algae in diesel fuel tanks?

In the last 7-8 years, the number of occurrences of petroleum storage tanks contaminated with “algae” has increased dramatically across the country. We put that in quotes because we know it’s not truly “algae,” but rather mold, fungus, and bacteria that are responsible for the fuel. We call it algae because that’s what people assume it is (it’s not, because algae is a small plant creature that requires light to thrive, and gasoline tanks are too dark to provide that light), but we go with it. Whatever you call it, whether it’s algae, bacteria, or fungus, the problems remain the same.

Problems? That is the topic of discussion today. How to tell if you have an algae issue in your gasoline tank.

There’s a mountain of research and data that explains what causes diesel fuel algae to contaminate a tank. Due to the lack of sulfur in the gasoline (which prevents it from growing), any free water in the tank becomes a breeding ground for this fuel “algae.” But how do you determine if you have an issue with diesel fuel algae? Take a look at these red flags that could indicate a problem.

1. You insert the petrol tank in the ground and look for any substantial depth of water. Microbes and diesel fuel algae can grow and thrive in as little as a quarter-inch layer of water at the bottom of the container. Remember that a quarter inch can represent tens of gallons of water in a storage tank, depending on the size of the tank.

2. You go through filters more quickly than usual. Because the microbial bodies as well as the black, slimy biomass matrix that they make throughout the course of their lifespan get captured, diesel fuel algae clogs filters like crazy (s). Filters are also clogged when microbial activity causes the gasoline to lose its storage quality and degrade at a faster rate. The asphaltenes and heavy end fuel components that have stratified and come out of solution then cause filter blocking. Any unusually high incidence of filter plugging is a sign that the tank needs to be checked for microorganisms.

3. You perform a microorganism test, which results in a positive result. Microbe test culture strips can be purchased for around $10 apiece. The test takes 3-4 days to create and will provide you with a qualitative (yes/no) rather than quantitative (yes and how much) response to your question.

4. The pH of your gasoline is lower than it should be. Algae in diesel fuel create acids, which gradually shift the pH of the fuel towards an acidic state. Because a pH of 7.0 is neutral, adding acid to the fuel will lower the pH. A fuel pH of less than 5.8 indicates a major problem in the tank and is strong evidence of a microbial problem. Of course, you’ll need a pH meter to figure this out, but if you have one, it’s another piece of data you may gather to see if you have a diesel fuel algae problem.

After you’ve confirmed that, you can move on to the next step in resolving the issue.

What can I use to clean a diesel tank?

Fill the tank with a few gallons of water and a scouring medium, such as shards of safety glass or clean gravel. Add a liquid soap with petroleum-cutting characteristics, such as Dawn, Ajax, or Palmolive, and rapidly swish it around in the tank.

Can algae grow in diesel fuel?

Algae cannot thrive inside a diesel fuel tank, according to science. Algae cannot grow in the darkness of a diesel fuel tank because it requires sunlight to grow. Microbes such as mold, bacteria, and fungus, on the other hand, can find their way into your diesel fuel tank and cause havoc if you’re not careful. It is critical that you avoid allowing these bacteria to cause damage to your fuel and fuel tank at all costs.

When a large amount of free water is able to work its way into your diesel fuel tank, microbes can set up shop. To thrive, the microorganisms require both food and water, and the diesel fuel and water provide them with everything they require to expand their colonies. Microbe colonies can render your diesel fuel useless in a short amount of time, forcing you to pay for costly repairs.

While you can’t always observe microbial development in a diesel fuel tank, there are some pretty straightforward techniques to tell if you have “algae” growing in your tank. You can keep track of how often your fuel filters need to be replaced by keeping an eye on them. When bacteria are present in your fuel, your fuel filters may clog up more quickly than usual. You can also do frequent testing on your diesel fuel tank to detect if it contains bacteria. These tests will tell you if you need to be concerned about a microorganism problem.

If you discover that algal sludge has formed in your diesel fuel tank, the first thing you should do is drain the water and thoroughly clean the tank. Algae sludge must be broken up and removed from your tank. Initially, do not purchase a biocide; it will not address the problem until the water has been removed and the biomass has been dissolved.

Don’t use too many additives. Too much of anything is bad and will only lead to additional issues.

How do I stop algae in my diesel tank?

Algae growth in diesel fuel tanks is a risk that all diesel users should be aware of. A few basic efforts may be taken to solve and prevent this rising problem.

Diesel algae can be avoided by keeping the water level in the tank at a constant level. Water buildup in diesel fuel can be controlled with the use of a water controller. Drain excess water and treat the fuel with a regulated biocide if algae begins to form in the fuel tank.

What color is algae in diesel fuel?

How is it possible for something to grow in diesel fuel? Technically, it doesn’t grow in the fuel; rather, it grows at the water-diesel fuel interface. Water is the only thing it needs to survive. Condensation can cause water to develop in your gasoline tank. It can prematurely clog your filters if it gets bad enough. This problem is particularly common in older diesels that have been idle for long periods of time. Small black specks in your transparent pre-filters will be the first sign. You’ll have to look inside your fuel tank to see how bad it is. The best way to do this is to remove the gasoline sending unit. If your tank is completely black, as shown in this image, you most likely have algae growth.

What will dissolve diesel sludge?

Technol 246 from Dieselcraft is a fuel additive that penetrates and dissolves diesel sludge buildups in diesel fuel tanks to eliminate filter blockage issues.

Diesel sludge, also known as tank contamination, is an algae-like substance in which cells attach to one another on the tank surface or at the fuel water interface. When a vehicle is fueled, the sludge settles to the bottom of the tank and can clog filters.

A shell of extracellular polymeric substance surrounds these biological structures, protecting the bacteria from biocides and most other chemicals. Technol 246 disperses the sludge into smaller particles that flow through filters and nozzles without clogging or causing damage.

According to Dieselcraft, the cleaned-up fuel will emit less NOx, carbon monoxide, and particulate matter. Poor combustion produces black smoke, which is removed, preventing further biological growth and increasing fuel economy.

According to Dieselcraft, normal treatment costs are around 2 cents per gallon of fuel.

8 ounce bottles, 1 gallon, 5 gallon, and 55 gallon containers of Technol 246 are available. A self-contained tip and measuring bottle are included in the 1 gallon container. 8 ounces of Technol 246 will treat up to 275 gallons of gasoline, and 1 gallon of additive will treat up to 4,000 gallons of fuel, according to Dieselcraft.

What happens if you get water in your diesel tank?

Anyone who works with diesel fuel, from builders and landscapers to delivery companies and auto dealerships, is aware that water issues are a constant concern. Whether you preserve it for a long time or not, this is the situation. You’re in big trouble if water gets into your diesel fuel system. Contamination of water wreaks havoc on this powerplant. Let’s have a look at the primary reasons why water and diesel don’t mix.

We all know that water freezes. However, did you know that it freezes faster than gasoline? Here’s an example of a comparison:

When water gets into your gasoline, it freezes, resulting in issues such as power loss, clogged filters, corrosion of fuel parts, and injector damage. That’s why, if there’s water, you’ll notice greater problems in the winter.

Gas is more refined than diesel, so while having water in your gas tank is bad, it’s even worse with diesel because it holds on to more water. In addition to the issues listed above, your engine’s lifespan may be shortened, and repairs may be costly. If you need to repair a fuel injector because it exploded, for example, it will be expensive.

Diesel and water, like oil and water, do not mix; instead, they separate. As a result, if you have water in your tank, it will settle to the bottom. Your tank will corrode and algae will bloom as a result of that water. Rust floats about in your gasoline filters, obstructing and ruining them. Bacteria create waste and continue to eat away at the engine and its components.

It’s not uncommon for condensation to form and then dissipate as the temperature outside changes. That isn’t the issue. It occurs when there is an excessive concentration of water. When this happens, problems like engine power loss arise. Examine the fuel; if it’s clear, that’s a good sign. There’s a problem if it isn’t, for example, if it’s cloudy. That is why routine maintenance is critical.

There’s a good likelihood you have water difficulties if you notice your vehicle or equipment isn’t performing well, especially if the idling is inconsistent. If the engine cuts off during acceleration, there are two alternative ways to tell.

Microbes multiply quickly in your tank, produce waste, and are difficult to eradicate. This is especially true if the underlying water problem isn’t addressed, as bacteria and fungus require water to survive.

A gasoline additive might work if there isn’t much water in the tank. Otherwise, the tank will have to be drained. If you have an above-ground tank, this is the best and most complete option. After that, clean the inside and remove any rust or corrosion. If you haven’t done this in a long time, your tank may need to be fixed or replaced. Ricochet Fuel can assist you.
