As an operator or owner of a fuel storage tank, you are responsible for not only maintaining great fuel quality but also its integrity. Hence, you know just how important it is to keep water out. Water contamination can have devastating consequences and must be avoided at all costs. Hence, let’s explore effective strategies on how to prevent water from entering your fuel tank. We guarantee that by following these preventative measures, your fuel inventory will remain clean and business operations will flow smoothly. How does water enter fuel tanks? Poor and inconsistent maintenance coupled with inadequate sealing allows entry of rainwater. In cooler temperatures, water makes its way into fuel tanks through condensation contaminating diesel, oil, and gasoline. Biofuels are also at risk for water contamination, as they are hygroscopic, meaning they have a strong attraction to water. Such issues can be prevented easily through regular professional cleaning of fuel storage tanks. What happens after water contamination? Water contamination can cause a variety of problems. When unresolved such situations worsen and necessitate expensive repairs. Since oil and water do not mix, they separate into layers with oil forming a layer above water. As time passes, water trapped at the bottom of a tank causes and accelerates the formation of rust, which weakens a tank’s structural integrity and results in holes and cracks. Furthermore, water accumulation causes microbial contamination because microbes exist in soil, air, and rainwater. Once they start interacting with fuel, they result in excessive and dangerous microbial growth. Through the fuel dispenser pump or gas dispenser, these microbes then make their way into a vehicle’s fuel tank. Unfortunately, problems caused by water contamination do not end here, as it also causes degradation of stored fuel, which consequently causes severe engine damage and failed exhaust emissions. To some extent, filters prevent water buildup but they are also susceptible to clogging. Is water removal from fuel tanks possible? Yes, there are several methods by which water can be removed from fuel tanks. Bilge pumps work efficiently, however, they are unable to eliminate water sources. Emulsifying water additives which burn off water can also be used. Fuel polishing, which filters fuel, is a great option for removing water from biofuels. Simple tips Frequently collect dispenser samples, identify possible water entry points, and regularly extract and examine fuel from the bottom. To diligently monitor your tanks, install an automatic water detection system. Conclusion Keeping water out of fuel storage tanks may not be easy, but it is possible. Hence, we recommend using and following the aforementioned information and tips to prevent water contamination.
