Center Enamel Provides Glass-Fused-to-Steel Tanks for Wuzhou Municipal Sewage Treatment Plant
Center Enamel has played a crucial role in advancing urban environmental infrastructure through its contribution to the Wuzhou Government's municipal sewage treatment project. Completed in October 2018, this project exemplifies Center Enamel's engineering capability to deliver high-quality, durable, and efficient containment solutions tailored for complex municipal wastewater challenges.
Project Overview and Double-Wall Specifications
The Wuzhou Municipal Sewage Treatment Plant required specialized containment systems to meet strict technical and environmental safety regulations. To fulfill these demands, Center Enamel supplied and installed an advanced double-wall tank configuration, ensuring optimal leakage prevention and structural resilience:
● Project Location: Wuzhou city, Guangxi Province
● Inner Tank Dimensions: Ø6.11m × 3.6m
● Outer Tank Dimensions: Ø12.99m × 3.6m
● Tank Color: Dark green
● Roof Type: Open roof configuration
● Coating Technology: 2 Enameling, 2 Firing (two-coat, two-fire thermal fusion process)
● Completion Date: October 2018
Advanced Engineering for Municipal Wastewater Security
Handling municipal sewage requires materials that resist aggressive chemical and biological degradation while maintaining structural integrity. Center Enamel's Glass-Fused-to-Steel (GFS) technology offers distinct operational advantages:
● Permanent Glass-Steel Fusion: Porcelain enamel glass is fused to high-strength structural steel at extreme temperatures (820°C to 930°C), creating an inert, non-porous vitreous surface that completely resists wastewater corrosion, hydrogen sulfide, and chemical etching.
● Double-Wall Containment Security: The concentric inner and outer tank structure provides a secondary layer of protection, mitigating environmental risks and ensuring maximum safety for municipal fluid storage.
● Modular Bolted Flexibility: Prefabricated bolted panels enable rapid on-site assembly, minimizing civil construction timelines and reducing long-term maintenance costs.
Comparative Matrix: Municipal Wastewater Storage Technologies
Evaluation Parameter | Center Enamel Double-Wall GFS Tanks | Single-Wall Cast-in-Place Concrete Basins | Traditional Welded Carbon Steel Tanks |
Leakage Prevention & Redundancy | Concentric double-wall design provides built-in secondary containment and maximum safety | Single-wall structure prone to micro-cracking and hidden subsurface seepage | Single-wall welded panels vulnerable to localized weld seam corrosion |
Corrosion & Chemical Resistance | Permanent glass-steel fusion completely resists sewage chemicals and biological loads | Vulnerable to concrete carbonation, acid attack, and hydrogen sulfide degradation | High susceptibility to interior oxidation and coating delamination |
Installation Speed & Rigging | Rapid modular bolted erection completed efficiently on-site | Extremely slow civil construction requiring formwork, pouring, and curing | Slow field construction requiring complex manual welding and site coatings |
Frequently Asked Questions (FAQ)
Q: What was the scope of Center Enamel's project for the Wuzhou Municipal Sewage Treatment Plant?
A: Center Enamel supplied a specialized double-wall GFS tank system consisting of an inner tank measuring Ø6.11m × 3.6m and an outer tank measuring Ø12.99m × 3.6m, completed in October 2018.
Q: Why was a double-wall tank design chosen for the Wuzhou sewage project?
A: The double-wall configuration provides an extra layer of structural redundancy and leakage protection, which is critical for municipal sewage treatment facilities operating near urban and environmentally sensitive areas.
Q: What coating technology is applied to these Wuzhou wastewater tanks?
A: The tanks utilize a rigorous 2-enameling, 2-firing coating process, permanently fusing glass enamel to high-strength steel to ensure superior chemical resistance and a multi-decade service life.
Q: What color and roof configuration were specified for the installation?
A: The tanks were finished in a uniform dark green exterior color and utilized an open roof design tailored to the plant's operational workflow.
