Center Enamel: Engineering the Future of Wastewater Treatment with Advanced Bolted Steel Tanks
Water is the foundation of life, but as global industrialization and urban growth accelerate, so too does the challenge of managing the world’s most precious resource. Every day, billions of gallons of wastewater—from industrial plants, municipal systems, and agricultural operations—must be treated to protect both people and ecosystems. Effective wastewater treatment is not only about compliance; it is about safeguarding the planet’s future.
At the forefront of this mission is Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), China’s leading bolted steel tank manufacturer and a recognized authority in global storage and water treatment solutions. Since 2008, Center Enamel has delivered innovative Glass-Fused-to-Steel (GFS) and Fusion Bonded Epoxy (FBE) tanks to over 100 countries, providing sustainable infrastructure for municipal wastewater treatment, industrial effluent management, and sludge processing.
Through continuous innovation, international certification, and proven global project experience, Center Enamel has redefined what wastewater treatment infrastructure can achieve—combining engineering precision, sustainability, and superior durability in each project.
The Role of Storage Tanks in Wastewater Treatment
In wastewater management systems, storage tanks serve as the core processing units that both contain and treat contaminated water or sludge. They are essential at every stage of the treatment process:
1. Equalization Tanks: Buffer flow and stabilize wastewater characteristics.
2. Aeration Tanks: Support microbial oxidation and biodegradation.
3. Clarifiers and Settling Tanks: Separate solids from liquids.
4. Sludge Holding Tanks: Store concentrated waste solids before dewatering or reuse.
5. Effluent Storage Tanks: Safely store treated water before discharge or redistribution.
These tanks must withstand corrosive gases, fluctuating temperatures, high biological activity, and variable hydraulic loads. Traditional concrete or welded steel structures often fail over time due to chemical attack, leaks, or structural fatigue.
That’s where Center Enamel’s bolted steel wastewater treatment tanks deliver a transformative advantage—combining advanced coating science with modular construction to ensure performance, longevity, and environmental safety.
The Power of Center Enamel’s Coating Technology
Glass-Fused-to-Steel (GFS): The Industry Standard for Corrosion Resistance
Center Enamel pioneered the development of Glass-Fused-to-Steel (GFS) technology in China—an innovation that revolutionized the nation’s wastewater treatment infrastructure. The process involves fusing molten glass to specially selected steel plates at temperatures between 820°C and 930°C. The high heat forms a strong chemical bond between the steel substrate and the glass surface, creating a coating that is both physically resilient and chemically inert.
Key Advantages of GFS Coating:
· Corrosion Resistance: Performs exceptionally well in acidic, alkaline, and biologically active environments (pH range: 1–14).
· Smooth, Non-Porous Surface: Prevents scaling, microbial adhesion, and contamination.
· Chemical Stability: Resistant to hydrogen sulfide, chlorine, and wastewater gases.
· Durability and Strength: 30+ year service life under continuous chemical exposure.
· Easy Cleaning and Maintenance: Glossy surface resists sediment buildup, reducing maintenance and downtime.
This unique coating technology makes GFS tanks ideal for harsh wastewater environments, ensuring lasting protection against corrosion and minimizing lifecycle costs.
Fusion Bonded Epoxy (FBE) Coating: Seamless Protection for Harsh Conditions
For specific industrial wastewaters with aggressive chemical profiles or where customized coating flexibility is needed, Center Enamel also provides Fusion Bonded Epoxy (FBE) coating technology.
Applied as a dry epoxy powder and cured at high heat, FBE coatings form a consistent, bonded layer resistant to impact, abrasion, and corrosion. They are particularly effective in protecting tanks used in industrial wastewater, chemical effluent containment, and leachate treatment applications.
Together, GFS and FBE technologies allow Center Enamel to offer tailored tank solutions for every wastewater scenario—industrial or municipal, acidic or neutral, high-temperature or ambient.
Superior Construction: The Bolted Steel Advantage
Center Enamel’s wastewater treatment tanks are based on a modular bolted design—a manufacturing approach that merges precision engineering with project flexibility.
Design Benefits:
· Prefabricated Panels: Each steel plate is coated and cured in controlled factory conditions for maximum quality.
· On-Site Assembly: Panels are bolted together using corrosion-resistant fasteners and gaskets, ensuring a watertight seal.
· Fast Installation: Project timelines are reduced by up to 50% compared to concrete or welded tanks.
· Scalability: Tanks can be expanded or relocated with minimal cost impact.
· Reduced Construction Risk: No welding, curing, or heavy scaffolding required at project sites.
Structural Integrity and Safety
GFS and FBE-coated tanks are engineered to the highest international standards, ensuring exceptional performance under demanding operating conditions. Designs are validated for pressure loading, seismic forces, and wind resistance. Every tank is carefully sealed to achieve gas-tight and liquid-tight performance—critical in aeration and anaerobic treatment processes.
Center Enamel also offers aluminum dome roofs, floating covers, or open-top configurations, depending on process requirements.
Meeting Global Design and Quality Standards
Center Enamel’s wastewater treatment tanks align with major international engineering and quality standards:
· AWWA D103-09: Bolted Steel Tanks for Liquid Storage.
