In the realm of municipal and industrial wastewater treatment, the choice of storage and processing tanks is critical. These environments demand tanks that are not only durable but also resistant to the harsh conditions and chemicals present in wastewater. Epoxy coated steel tanks emerge as the ideal solution, combining robustness, corrosion resistance, and ease of maintenance to meet the rigorous demands of wastewater treatment facilities.
Epoxy coated steel tanks stand out as the premier choice for municipal and industrial wastewater treatment plants. Their unmatched durability, superior corrosion resistance, ease of maintenance, and environmental safety make them an essential component of any wastewater treatment infrastructure. By choosing epoxy coated steel tanks, municipalities and industries can ensure their wastewater treatment operations are efficient, reliable, and compliant with environmental standards. Investing in these tanks is a strategic decision that guarantees long-term performance and cost-effectiveness, safeguarding the integrity of wastewater treatment processes for years to come.
With over 30 years of experience in tank research, production, and construction, Zhengzhong Technology, in collaboration with the leading global paint and coating manufacturer AkzoNobel, has jointly developed Fusion Bonded Epoxy (FBE) coating technology. Epoxy coating is an advanced anti-corrosion coating known for its exceptional corrosion resistance and adhesion properties. Moreover, the epoxy coating technology employs special construction techniques such as electrostatic spraying, enhancing coating uniformity and adhesion, thereby significantly extending the tank's lifespan.
Tanks coated with epoxy coating technology not only boast advanced technology and cost-effectiveness but also offer convenient and swift installation. Their quality meets the requirements of standards such as AWWA D103-09 and ISO 9227/ASTM B117, garnering immediate recognition from customers upon introduction.

Advantages of Epoxy Coated Steel Tanks
Unmatched Durability and Strength
Epoxy coated steel tanks are renowned for their exceptional strength and durability. The steel provides a solid structural foundation capable of withstanding significant pressure and weight. This makes them suitable for large-scale applications in both municipal and industrial settings. The steel's inherent strength ensures the tanks can handle the substantial volumes of wastewater processed daily in these facilities.
Superior Corrosion Resistance
One of the most compelling advantages of epoxy coated steel tanks is their superior resistance to corrosion. Wastewater contains a mix of organic and inorganic substances, many of which are corrosive to unprotected metal surfaces. The epoxy coating acts as a robust barrier, preventing the steel from coming into contact with these corrosive agents. This not only extends the life of the tanks but also ensures they remain safe and reliable over long periods.
Maintenance and Cost Efficiency
Epoxy coated steel tanks are designed for ease of maintenance. The smooth epoxy surface prevents the build-up of sludge and scale, making regular cleaning and maintenance tasks simpler and less time-consuming. This efficiency in maintenance translates to cost savings over the tank's lifespan, reducing downtime and operational disruptions.
Environmental and Safety Considerations
In wastewater treatment plants, environmental and safety considerations are paramount. The epoxy coating used on these tanks is often formulated to be environmentally friendly and safe for the storage of wastewater. This ensures that there is no risk of contamination to the surrounding environment, aligning with the stringent environmental regulations governing wastewater treatment facilities.
Customizable and Versatile
Epoxy coated steel tanks offer a high degree of customization to meet the specific needs of different wastewater treatment plants. They can be manufactured in various sizes and configurations, allowing for optimal space utilization and process efficiency. Additionally, these tanks can be equipped with features such as internal baffles, external supports, and advanced monitoring systems to enhance their functionality.
Proven Performance in Diverse Applications
The proven performance of epoxy coated steel tanks in diverse applications further underscores their suitability for wastewater treatment. From small municipal treatment plants to large industrial facilities, these tanks have demonstrated their ability to reliably store and process wastewater under challenging conditions.
