Corrosion is the breakdown of metal. It is a common problem in all water tanks as they become prone to rust and decay due to the heavy long-term use of the structures. Corrosion is an ever-present issue with water storage tanks that must be addressed through good tank maintenance.
Although it is impossible to stop all corrosion as tanks age, there are newer and better ways to protect them with anti-corrosive coatings and other means.
How Does Corrosion Happen?
Corrosion occurs when metal deteriorates due to a chemical reaction between the metal and the surrounding environment. It is a natural process that can potentially cause severe damage to your water tank, leading to a considerable expense in finding a solution to fix the problem.
All metals can corrode, especially if they do not have a protective coating which can lead to the metal substrate of water tanks breaking down, leaving tanks no longer functioning correctly. Both the metal type and the conditions of the environment, such as gases that encounter the metal, can affect the form and rate of deterioration.
Identifying Corrosion in Water Tanks
Metal structures are prone to corrosion and rust from long-term usage. Even regularly cleaned water tanks are still susceptible. Cracks and leaks within the structure are ideal for bacteria nesting spots.
The first signs of corrosion and rusting may be a general dulling of the surface of your water storage tank. It also becomes quite rough. Over time, it may cause crumbliness due to the instability of the metal.
When iron corrodes, it begins to rust, taking on a color similar to orange-brown, which darkens the older it gets. Something already that color, like copper, will appear blue-green once corrosion develops.
If you spot that your water storage tank is breaking down, then corrosion is potentially taking place inside the water storage tank. At this point, your water storage tank will need either relining or replacing.
Water Tank Corrosion-Protection Measures
There are several tips and techniques that can help prevent corrosion in water tanks. The following are some of the most effective:
1. Choose the right materials
Choose a tank made of high-quality materials that are resistant to corrosion. Tanks made of stainless steel, fiberglass, and polyethylene are excellent options because they are durable, resistant to corrosion, and require minimal maintenance.
2. Implement a regular maintenance schedule
As a tank owner, take the time to have a professional tank inspection company inspect your tank for signs of corrosion, such as rust, discoloration, or leakage. They should also clean the tanks on a regular basis to eliminate any silt, debris, or germs that can accelerate corrosion.
3. Use protective coatings
The most common method of corrosion control is coating the tank wall with paint. Epoxy and polyurethane coatings are two common types of protective coatings that effectively prevent corrosion.
The paint coating forms a physical barrier between the tank wall and the water. Both must be relined whether you have a new or existing water tank. Tank relining prevents bacteria growth, which helps prevent corrosion and water tank contamination. The coating must be maintained regularly as part of the routine water storage tank maintenance.
4. Install a cathodic protection system
A cathodic protection system is an electrochemical technique that can help prevent corrosion in water tanks. It works by introducing a sacrificial metal, such as zinc or magnesium, into the tank, which corrodes instead of the tank. This system is especially effective in tanks that contain saltwater or other corrosive liquids.
Wrapping Up
Corrosion costs are enormous each year as they must pay for water tank replacements or refurbishments due to not spotting corrosion in their water retaining structures. That is why it is essential to know how to protect your water tank from corrosion to avoid these problems.
We hope you find this article helpful. By following the tips we’ve discussed earlier, tank owners can extend the lifespan of their tanks, reduce the risk of contamination, and save money on costly repairs.
