Water tanks are vital assets, serving essential roles in both residential and commercial settings. However, being metal structures exposed to water, they are susceptible to corrosion over time. It’s crucial to acknowledge that corrosion within a water system can compromise water quality, impart an unpleasant taste, and pose potential health risks. Furthermore, if left unaddressed, corrosion can lead to catastrophic failure of the water tank.
Fortunately, corrosion in metal water storage tanks is preventable or manageable, ensuring continued effective operation of your water storage system. As the adage goes, “prevention is better than cure,” it’s prudent to take proactive steps and prepare for potential issues, understanding that corrosion can be mitigated with appropriate measures.
In this article, we will delve into strategies for preventing corrosion in metal water storage tanks. It’s essential to heed these methods to safeguard your structures against corrosion.
What is Tank Corrosion?
Corrosion in tanks occurs due to electrochemical interactions between the metal surface and the soil or groundwater, causing deterioration of the metal surface. In essence, the tank material gradually dissolves in the water held within, causing structural damage to the tank.
According to the Environmental Protection Agency (EPA), approximately fifty percent of underground storage tanks display varying degrees of corrosion by the time they reach fifteen years of age.
What Causes Corrosion in Water Tanks?
When reflecting on your chemistry lessons, you’ll remember that metals or steel undergo chemical reactions when they come into contact with water and oxygen, resulting in chemical changes.
Here are some of the primary factors contributing to corrosion in water storage tanks with metal cages:
1. Oxidation
Metal oxidation stands as a key contributor to corrosion in water tanks. This phenomenon occurs when oxygen present in the water interacts with the metal, resulting in its degradation. Generally, two main types of oxidation occur: galvanic corrosion and chemical oxidation.
Galvanic corrosion occurs due to the direct contact between different metals or exposure to battery acid. Conversely, chemical oxidation arises from the interaction between metal ions and atmospheric oxygen.
2. Rust Formation
Rust is the enemy of metal! It occurs when iron reacts with oxygen and water, forming a reddish-brown powder that accumulates on the surface. Over time, this buildup weakens the metal, creating holes and leaks. Basically, rust eats away at the metal, making it weak and unreliable.
3. Carbonation
Carbon dioxide (CO2) can be bad news for concrete. Over time, CO2 from the air can seep into concrete and react with the chemicals that hold it together. This process, called carbonation, weakens the concrete’s natural alkalinity, which is like a shield against corrosion. As CO2 dissolves in the water within the concrete, it creates weak carbonic acid, which slowly eats away at the concrete’s strength.
How to Prevent Corrosion in Water Tanks?
Despite the significant risk of tank corrosion and subsequent damage, there are preventive measures you can implement to mitigate such issues. Don’t fret; simply follow these guidelines:
- Ensure proper tank installation. Verify that the tank is installed correctly, with its cap tightly sealed to prevent groundwater infiltration. Examine the seams for any indications of leakage.
- Schedule regular inspections. Promptly arrange for professional inspections whenever equipment or components display signs of malfunction.
- Maintain your tank diligently. Adhere strictly to the manufacturer’s maintenance instructions during routine upkeep. Avoid overfilling the tank to prevent potential issues.
- Install and maintain safety valves. Ensure all safety valves are installed and functioning correctly to prevent tank overflow in case of emergencies or malfunctions.
- Check for signs of corrosion. Regularly inspect your tank for stains, bulging, or leaking joints, as these may indicate corrosion. Stay vigilant and conduct thorough inspections regularly.
Remaining vigilant and taking responsible actions are key to preventing further damage and maintaining your tank in optimal condition.
