How to Prevent Microbial Growth in Your Silvan Tanks?

Silvan tanks are among those top-of-the-line fuel containment systems that are reputed for their unique characteristics. Manufacturers have them built with enhanced efficiency and safety features, however, these positive notes about them do not necessarily take away the fact that proper maintenance practices should be put into perspective to protect the liquid fuel it contains inside.  

Even if these occurrences seem to be limited, diesel fuel microbial contamination is likely to produce challenges and difficulties such as: 

  • plugged filters
  • reduced combustion efficiency
  • injector malfunctions
  • increased rates of corrosion
  • fuel flow problems

Microbial growth

Microbial growth in fuel tanks is caused by no other than fungus and bacteria. This kind of growth is likely to take place the moment that water has found its way to your liquid fuel storage tank and your diesel’s temperature is anywhere between 10C to 40C. 

Fungal spores and bacteria can be found everywhere, they can be found anywhere but have high concentrations in the soil. They can find their way to your fuel tank in various ways, such as through your fuel vent system. Another is through contamination during the refilling process. 

When water vapor inside your fuel tank condenses, this will eventually create a suitable condition for microbial growth to take place. Usually, microbial growth will occur at the water-fuel interface which is at the bottom part of the tank. The biomass production and microbial growth melding together will result in a dark slime.

It takes on the appearance of algae, others have asserted that it is comparable to a chocolate mousse. This sludge, when they accumulate and grew or spread on the bottom part of your storage tank, that means to say that the conditions are already severe, and thus necessitating immediate action.  

Prevention

fuel tanks and storage

If you want to prevent microbial growth in your fuel storage tank, the best, cheapest, and easiest way to do it is to limit the amount of water that can get into your tank. Initially, we suggest that you check or inspect your tank every month and see to it that the bottom parts don’t have water in them. You may decrease frequency gradually if you are certain no water is found. Twice a year, make it a habit or as part of your tank maintenance routine to have it checked for water presence.  

Most fuel tanks do have drain plugs, and they are usually located at the bottom part of it, too. Use this feature to regularly drain your tank. In the absence of drain plugs, you may come up with other mechanical means. Water leaking into your underground storage tanks must be prevented at all costs.  

Check your fuel tank vents and make a way to install a filter system on them. This measure will help prevent fungal and bacterial spores from finding a way to get inside your fuel containment system or tank. Maintenance, periodic tank cleaning, and inspection should be among the prioritized. 

We are not encouraging you to skimp on the above-suggested measures, but another option you can consider is the use of approved fuel preservative. Such products can provide substantial help in delaying or implementing some control on the buildup of microbial growth. As for the fuel treatment frequency, this aspect though will depend on how fast the growth (microbial) will go.  

What Are Self-Bunded Tanks?

What Are Self-Bunded Tanks?

Bunded tanks, otherwise known as double-walled tanks, are efficient containment system for your high-value liquids. If you are working for an enterprise that is involved in the trading or use of diesel fuel, petrochemical products, oil and used oil, etc, then nothing can be more practical than the use of double-walled tank to contain them.

The distinct feature of self-bunded tank is that they have inner and outer tanks. There is a gap between them, which is 110% of the capacity of the inner tank. The main purpose of this gap between them is that in the event of leakage or spill there is something to catch them, thus in the process preventing environmental contamination. This explains the reason why we qualify them as among the safest and most secure ways to store your high-value liquid.

Durability

Did you know that one of the reasons why there is a high industry demand for self bunded diesel tanks today? Apart from the fact that they bring along highest safety standards you may ever need or look for in a fuel tank, they are also designed and built tough.

The double steel walls of this type of tank will help prevent your stored liquid from spilling or leaking. If, by chance, due to some unfortunate incident that there occurs a leak through the first wall, there is still no reason to feel worried about.

Why?

You see, the second wall or tank is right there to contain them. It has more than enough room to accommodate the content of the first tank. Thus, keeping your stored liquid fuel to spill through and contaminate the immediate surrounding environment.

Cost Effective

If you happen to have a large amount of liquid to contain and store, bunded fuel tanks would be the best way to go for this. The capacity for this type of tank would usually range from 1,000 to 150,000 liters. If you are involved in a business organization with a constant need for storing a huge amount of liquid in your work site or facility, there is no reason why your personnel or staff will leave the premises just to refuel their vehicle or machinery.

The easy installation features for this type of tank will minimize the time and costs needed to set it up. It comes with a safe fuel limit, and this is a 10% greater when compared to standard tanks having similar capacity. This means to say that your tank is bound to go long in between refills.


Why Is It More Advantageous to Use Bunded Tanks?

Here are some of the good reasons why you should use them as your fuel containment system.

  • Huge storage capacities, from 1000 to 110,000-litre
  • Improved safety level for personnel and environment
  • Meets Australian Standards
  • Eliminates the need for external bunding
  • No specialist needed
  • Operational within a few hours after delivery
  • Prevents spillage and leaks
  • Reduce possibility of machinery downtime
  • Safe and secure liquid containment system
  • Transportable as containers by rail, road and sea
Dangerous Chemicals Warning

Due to the stringent industry regulations and environmental laws here in Australia, the use of bunded fuel tanks and similar bunded storage systems has become a must for every business entity that ideas with liquid fuel or any other high-value liquid to be stored on their work site. Needless to say, self bunded chemical tanks earned a good reputation for themselves by proving that they are an effective and safe storage system.
