The Cornerstone of Public Health: Advanced Steel Tanks for Treated Water Storage
Clean, safe, and reliable water is a fundamental necessity for human health, economic prosperity, and the functioning of modern society. From a municipal perspective, it is a public trust; for industries, it is a critical resource that underpins every process. The journey of water from its source to its final point of use involves a complex series of treatment processes to ensure it is free from contaminants. The final, crucial step in this chain is storage. The vessel that holds treated water is not a mere container; it is the final barrier that protects a purified, valuable commodity. A failure in this link—whether due to contamination, structural compromise, or degradation—can have catastrophic consequences, from public health crises to widespread industrial shutdowns.
At Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), we have engineered the definitive solution for this critical application. Our Steel Tanks for Treated Water Storage are meticulously designed and manufactured to the highest international standards, ensuring the safety, purity, and integrity of this most precious resource. By combining the structural strength of steel with advanced, inert, and durable coatings, we provide a storage solution that is not only robust but also fully compliant with the world's most stringent potable water regulations. Leveraging our signature Glass-Fused-to-Steel (GFS) and robust Fusion Bonded Epoxy (FBE) technologies, we are a global leader in delivering reliable, long-term storage for treated water.
The Criticality of Treated Water Storage
The act of storing treated water is governed by a set of non-negotiable imperatives that go far beyond simple containment. These requirements are the foundation of public health and operational reliability.
Unwavering Regulatory Compliance
For any tank intended for the storage of drinking water, regulatory compliance is paramount. It is the guarantee that the tank's material will not leach contaminants into the water. Our tanks are certified to a range of the most demanding global standards:
NSF/ANSI 61: This certification is a cornerstone of potable water safety. It verifies that a tank's components and materials will not have any adverse effects on drinking water.
WRAS (Water Regulations Advisory Scheme): This UK-based scheme ensures that water fittings and materials that come into contact with public water supplies are safe and compliant with UK regulations.
AWWA D103-09: This standard from the American Water Works Association governs the design and construction of factory-coated bolted steel tanks for water storage, providing a benchmark for structural integrity and material quality.
Any tank not holding these certifications poses a significant risk to public health and is often prohibited by regulatory bodies.
Protecting Water Quality
Treated water, while clean, is still a dynamic substance. During storage, it can be susceptible to the growth of microorganisms, including bacteria and algae, if the tank's interior surface provides a hospitable environment. The tank must act as an inert, hygienic barrier, preventing any biological or chemical contamination. This requires a smooth, non-porous surface that is easy to clean and sanitize.
Operational Reliability and Longevity
A tank holding treated water is a long-term asset, part of a permanent infrastructure that supports communities and industries. A tank failure can lead to severe service disruptions, costly emergency repairs, and potential health risks. Therefore, the tank's materials must be chosen for their durability, corrosion resistance, and a long service life, ensuring the asset provides decades of flawless performance with minimal maintenance.
The Flaws of Conventional Solutions
For decades, concrete and field-welded steel tanks have been the standard for treated water storage. However, both methods have inherent flaws that a modern solution must address.
Concrete Tanks: While strong, concrete is inherently porous and susceptible to cracking over time due to ground movement or thermal expansion. These cracks can allow contaminants to enter or water to seep out. Furthermore, concrete's rough surface can be an ideal breeding ground for microorganisms, and its construction is a lengthy, weather-dependent process with significant on-site labor costs.
Welded Steel Tanks: The on-site welding process is slow, labor-intensive, and the quality can be inconsistent, as it is highly dependent on the skill of the welder and the weather conditions. The weld seams are particularly vulnerable to corrosion, which can compromise the tank's integrity over time. The application of internal coatings in the field is also a complex process, with quality often compromised by dust, humidity, or inconsistent application.
Center Enamel's Bolted Steel Tanks: The Modern Standard
Our bolted steel tanks represent a revolution in treated water storage. By moving the most critical parts of the manufacturing process into our state-of-the-art factory, we eliminate the risks and inefficiencies of on-site fabrication. Our approach ensures a product that is faster to install, more reliable, and has a significantly longer service life.
Glass-Fused-to-Steel (GFS) Tanks: The Ultimate Solution
Our GFS tanks are the gold standard for treated water storage. As the first manufacturer in China to develop GFS technology, we have perfected a process of fusing a layer of inert glass to steel plates at over 820°C. The result is a composite material that combines the strength of steel with the unparalleled hygiene and corrosion resistance of glass.
NSF61 & WRAS Certified: This is our guarantee of purity. The GFS surface is certified to not leach any harmful substances into the water, making it a perfectly safe and non-contaminating choice for potable water.
Hygienic and Easy to Clean: The glassy, non-porous surface is impervious to bacterial and algal growth, ensuring water quality is maintained throughout the storage period. It is also exceptionally easy to clean and sanitize, reducing operational costs and downtime.
Unmatched Corrosion Resistance: The vitreous enamel is resistant to a wide range of chemicals, ensuring the tank's structural integrity against any residual disinfectants in the water.
Longevity: A GFS tank offers a design life of 30 years or more, with a Holiday test showing its resilience. It requires minimal maintenance, eliminating the need for periodic recoating or relining.
Fusion Bonded Epoxy (FBE) Tanks: A High-Value Alternative
For projects that require a high-value, durable solution, our FBE tanks are an excellent choice. The Fusion Bonded Epoxy coating is a robust, factory-applied polymer that provides superior corrosion resistance. While not as impervious as GFS, it offers a strong, uniform barrier. Its quality is ensured through our controlled manufacturing process, making it a reliable and cost-effective option for many treated water applications that require a high level of protection and durability.
