When a surface is continuously exposed to water, it can lead to corrosion. Water storage tanks are at high risk of developing corrosion as they store water for long durations. In a community, large water tanks are used to supply water to homes, where it is stored in residential tanks. Regardless of the storage capacity, both communal and residential tanks are susceptible to corrosion or rusting. Additionally, there exists a possibility of bacteria and other waterborne germs thriving in water that is stored for a long period of time without being used.
Storage tanks are a vital source of clean water for households; therefore, it is important to keep this source clean and free from all germs and bacteria in order to avoid any health issues in people who consume it. Tanks made of steel and other metals are more susceptible to corrosion compared to those made of glass fibre reinforced plastic (FRP). However, even FRP tanks can 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 iron reacts with oxygen, forming iron oxide compounds. Iron in drinking water can lead to many health issues. For instance, high iron content in the human body causes health problems related to the stomach and throat. In extreme cases, an iron overload also causes dysfunction of the liver and heart or diabetes in some vulnerable persons. Iron rich drinks and beverages are not even pleasant looking and also have a perceptible metallic taste. Water containing rust has a tendency to stain kitchen utensils and clothes when used for cleaning and washing.
Obviously, corrosion also reduces the lifespan of the storage tank. It is, therefore, recommended to protect 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 lower maintenance over time. Rhino Linings offers solutions for a range of applications such as wastewater treatment plants, sludge bins, reservoirs, sewer pump pits and steel holding tanks among others in addition to water storage tanks.
While epoxy solutions were widely used earlier for protection against leakage, spillage and corrosion, the industry is now adapting coatings as a new way of protection against these commonly occurring phenomena. Epoxies have been replaced by coatings because of better flexibility and extended lifespan. Polyurethane and polyurea coatings by Rhino Linings have become market leaders, serving the industry for the past 15 years and delivering superior solutions for spillage and corrosion problems in clean water 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, fibreglass, concrete and wood. 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 having them wear protective clothing while performing the task. Polyurethane and polyurea coatings are tested for a variety of conditions and applications before being made available for the market, and therefore, they continue to impress professionals across diverse sectors.
In addition to storage tanks, pipes transferring water to households are also susceptible to corrosion at some point in time and can lead to reduced pressure in taps due to clogging caused by particles and contaminants. Rhino’s innovative internal pipe spray system helps resist corrosion, increasing flow efficiency in pipelines.
