Various Benefits of Self-Bunded Tanks

One of the securest ways to contain and store your fuel or any other high-value liquid is the use of self-bunded tanks. These storage tanks are basically a tank within another tank. 

The main purpose of the outer tank sometimes referred to as the “bunded layer”, is to provide protection to the inner tank. It is the inner tank that holds and contains the fuel, hence, needing a good level of security. 

As for the outer layer, it is designed in such a way that it will hold a minimum of 110% of the contents of the inner tank. This feature allows for an extra safeguard of your high-value liquid in case spillage occurs. 

1.        Staying Compliant

Diesel fuel, petrochemical, and other similar high-value liquids should be stored in containment tanks that are not just strong but should be durable, too. More than that, it should have the required structural integrity to protect and secure its valuable liquid content. In commercial terms, any container with a storage capacitance for more than 200 liters, authorities necessitate it to be bunded.

2.       Protecting the Environment

If fuel spillage occurs,  there is one sure fire thing that will happen — it will eventually create havoc of unimaginable proportions to its immediate environment.  This is the reason why it is imperative for fleet managers to do everything in their power to prevent spillage and leakage from happening. 

This is where bunded fuel tanks come into the picture. They are primarily designed to protect your high-value liquids from spillage, so you can have your peace of mind knowing that they are safe and far from wreaking any harmful effect on the environment. 

3. Future Proof Your Fuel

It is natural for fleet managers to display a special kind of concern when it comes to finances and how they can help the business organization they belong to and work to make savings. 

It takes a good amount of understanding to see what bunded storage tanks represent and how imperative it is to see them as a form of investment that will certainly help you save significant amounts of money in the future. In complete contrast to what other cheaper alternatives do, bunded tanks can stand up against various weathering elements. This gives you a good level of assurance that your high-value fuel is safe for a much longer time. 

4. Theft Deterrent

Fuel theft is one of the most complained about issues in many business organizations, regardless of their industry. And there could be no better way to protect your company’s interests than by securing the high-value liquids you need in running your operation. 

The practical use of bunded storage tanks will ensure that you can track who among your staff or employees have a constant need for access to fuel, either for company’s provision for fuel or for running a piece of machinery in your facility. Bunded tanks are equipped with special monitoring devices so you can keep track of your fuel, oil, petrochemical stock and get alerts when you need to have a replenishment. 

The bunded feature for this type of storage tank for liquids will help discourage the would-be perpetrators of pilferage. The tank’s overall robust design and tough materials used for the tank will make it difficult for  anyone to get through the outer tank and into the inner tank where the liquid fuel is being kept.  

Conclusion: 

Make bunded tanks part of your comprehensive fuel management system. Fleet managers need to see and understand how such storage and containment facility could really help their operations before they would utilize it. 

Preventing and Removing Algae in Poly Diesel Fuel Tanks

Preventing and Removing Algae in Poly Diesel Fuel Tanks

Did it ever cross your mind that algae or any other type of microorganism could actually exist and thrive inside poly diesel fuel tanks?  Yes, there are. They may not be visible with the naked eye but they can thrive in them. As a matter of fact, there are many different types of diesel algae. They are also known as diesel bacteria.

The most common species for this type of bacteria is usually nestling right in the space gap found between the diesel and the water in your tank. This explains the reason why having water in your diesel tank is not advisable, but instead, you should take proper precautionary measures to keep water out and let it stay out. But for the vast majority of boaters, they almost always encounter water in their tank.

Water can find their way into your tank in many different ways, and when it does, bacterial growth is likely to follow and will do their thing. These microorganisms can regenerate exponentially, and for this reason, they are capable of multiplying themselves into vast number at an amazing rate.  

Once they grow in number, you will notice that your diesel fuel will start looking misty instead of bright yellow. When your personal bacteria population is left to grow, even more, you will even find brown sludge, flakes or slimy strands in your diesel, e.g. in your primary filter. Often, boaters only notice that they have diesel fuel algae, once they see their engine smoke producing more smoke, dropping in rpm or even just plain stalling (because their filters are clogged). In some cases, you might even notice a rotten egg smell coming from your diesel. When in doubt, you can buy bacteria tests, in order to examine if you have diesel algae in your diesel fuel.

How to Recognize Algae in Your Poly Diesel Fuel Tanks?

We have a mountain load of information that will tell us exactly what will make diesel fuel algae to appear and start contaminating a tank. Depletion of sulfur or the complete loss of which in the fuel will render even the small amounts of water in the tank to become a breeding ground for fuel bacteria or algae.

Sulfur in diesel can significantly help in preventing bacterial growth, therefore the absence or the loss of which in diesel means that there is no more deterring element in it that will help put a stop to their growth.

If you want to know if you have problem with your diesel tank due to possible bacterial growth, these warning signs may significantly help in pointing to a problem.

  1. You can stick your fuel tank and determine any significant depth in the water phase. Even a quarter of an inch layer of water at the most bottom part of your tank is good enough for microbial life to thrive and flourish.
  1. Your diesel or fuel’s pH level is much lower than it is supposed to be. The natural tendency of algae lurking in diesel fuel is to produce acids which may eventually askew your fuel’s pH level.  A 7.0 pH level is considered neutral, this will get reduced with the production of more acid by algae. Thus, decreasing the pH level. If your fuel pH is less than 5.8, then that indicates a major problem. It only goes to show that you have strong evidence of an ongoing microbe problem in your tank.
  1. If you will run a microbe test and results are showing affirmative signs, then there is nothing to deny that your tank is having a problem in this area. Test culture strips for microbes are available over-the-counter and they can be purchased at any given time of the day. The results for this test, though, would take a significant amount of time about 3-4 days. The results that it will show you will be qualitative (yes and no) and not quantitative (affirmative microbe presence by this much).   

Of course, there are plenty of other tips or pointers that you can use for this purpose like for instance giving these microorganisms some time to settle first prior to exterminating them. And it will be very helpful also if you have a couple of extra fuel filters on standby so you can just filter out dead microorganisms.

By the virtue of these pointers given above, you are increasing your chances of fixing this kind of problem in any of your poly diesel fuel tanks the very first time.  More from Silvan Tanks
