Water typically gets into a tank through condensation caused by temperature fluctuations.
Here's a more detailed breakdown:
-
Condensation: This is the primary way water enters tanks. When the temperature inside the tank differs significantly from the outside temperature, moisture in the air inside the tank can condense on the tank's interior walls. This condensation then drips down and accumulates at the bottom of the tank.
-
Temperature Fluctuations: As the reference states, temperature fluctuations between the tank's interior and its surroundings lead to condensation. For example, a warm day followed by a cool night can create significant temperature differences, encouraging condensation.
-
Contaminated Fuel/Substances: Water can already be present in the substance (like fuel) being added to the tank. Poor quality fuel or other liquids may contain dissolved or suspended water.
-
Leaks: Though less common, leaks in the tank, its lid, or its seals can allow rainwater or groundwater to enter. This is particularly relevant for tanks stored outdoors or underground.
-
Improper Ventilation: A poorly ventilated tank can trap moisture, increasing the likelihood of condensation.
Preventative Measures:
To minimize water accumulation in tanks:
- Maintain consistent temperature: Insulate the tank to reduce temperature fluctuations.
- Use desiccants: Add desiccants to the tank to absorb moisture.
- Regularly drain water: Drain any accumulated water from the bottom of the tank.
- Ensure proper ventilation: Provide adequate ventilation to prevent moisture buildup.
- Use high-quality fuels/substances: Ensure the fluids entering the tank are water-free.
- Inspect for leaks: Regularly inspect the tank and its seals for any signs of leakage.
