Corrosion is an inevitable phenomenon when a surface comes in contact with water, especially for a longer period. Therefore, water storage tanks are majorly susceptible to it as they store and carry water for long durations. Water storage tanks have become an integral part of communities’ water supply. There are usually big tanks that disseminate water to each house in the community, each with its water storage capacity. Both the communal and the residential tanks are susceptible to corrosion or rusting. Additionally, there exists a possibility of growing bacteria and other water-borne germs if the water is held for a long period without being used.
The Health Risks of Corrosion in Water Tanks
Water tanks are a vital source of clean water for households. Therefore, it is important to keep this source clean and free from germs and bacteria to avoid health issues in people who consume it. Tanks made of steel and other metals are more susceptible to corrosion than those made of glass fiber-reinforced plastic (FRP). However, FRP-based tanks also corrode after a few years of service.
Rusting is the most common type of corrosion that takes place in water tanks. Steel tanks are most prone to rusting over time. Rusting occurs when the iron content reacts with oxygen, forming iron oxide compounds, and iron in drinking water can lead to many issues. High iron content in the human body causes health problems related to the stomach and throat. In extreme cases, iron overload also causes dysfunction of the liver and heart or causes diabetes in some vulnerable persons. Iron-rich drinks and beverages are not even pleasant looking and have a significant metallic taste to them. Rusted water also tends to stain kitchen utensils and clothes when used for cleaning and washing.
The Importance of Anti-Corrosion Coatings
Corrosion, undoubtedly, decreases the lifespan of a storage vessel, and therefore, it is recommended to protect your tanks by coating them with anti-corrosion sprays for improved life and efficiency. High-quality coatings are necessary for tanks containing liquids in order to ensure protection from all contaminants and bacteria, which in turn leads to less maintenance over time. One such solution is provided by Rhino Linings for a range of applications such as wastewater treatment plants, sludge bins, reservoirs, sewer pump pits, steel holding tanks, etc., in addition to water storage tanks.
Advantages of Polyurethane and Polyurea Coatings
Epoxy solutions were widely used for protection against leakage, spillage, and corrosion-related issues. Still, recently, the industry has been improving by adapting coatings as a new way of protection against these commonly occurring phenomena. Coatings have replaced epoxies because of better flexibility and extended lifespan provided by coatings. Polyurethane and polyurea coatings by Rhino Linings have become market leaders serving the industry for the past 15 years and delivering the best solutions for spillage and corrosion problems in clean as well as wastewater plants.
These coatings are easily sprayed on or cast into water tanks in minimal workaround time. They also dry out in less than 24 hours making the water usable for people. Coatings available at Rhino Linings are highly versatile as they can be used on a variety of substrate materials, including steel, fiberglass, concrete, wood, etc. Our team consists of highly trained professionals who ensure that all areas are thoroughly covered with the coating. In addition, they ensure personnel safety by adorning protective clothing while performing the task. Polyurethane and polyurea coatings are tested for a variety of conditions and applications before being available for the masses, and therefore, they continue to impress every sector of professionals.
Protecting Water Pipelines from Corrosion
In addition to storage tanks, pipes transferring water to households are also susceptible to corrosion at some point in time. This can lead to reduced pressure in taps due to clogging caused by particles and contaminants. In that case, Rhino’s innovative Internal Pipe Spray System is a perfect solution that helps resist corrosion and impact, increasing flow efficiency in pipelines and thus reducing gas-related issues.
Frequently Asked Questions (FAQs):
How can you protect the water tank from corrosion?
One of the most effective solutions is applying anti-corrosion coatings, such as polyurethane or polyurea. These coatings form a protective layer that prevents rust and other forms of corrosion. Regular maintenance and cleaning of the tank, along with ensuring proper water circulation, can also help minimize corrosion.
Which methods can help control corrosion in water storage tanks?
Corrosion in water storage tanks can be controlled through several methods, including the use of corrosion-resistant coatings, such as polyurethane or polyurea, which protect the tank’s surface. Using corrosion inhibitors in the water, opting for non-metallic materials like fiberglass-reinforced plastic (FRP), and ensuring regular inspections and maintenance can also reduce the risk of corrosion.
