Center Enamel Supplies Advanced Glass-Fused-to-Steel Tanks for Beijing Daxing Anding Circular Economy Park Leachate Project
Center Enamel played an integral role in the successful completion of the Beijing Daxing Anding Circular Economy Park Leachate Project. This flagship environmental initiative underscores the company's commitment to delivering cutting-edge, sustainable containment solutions for municipal solid waste and hazardous liquid waste management in China.
Project Overview and Technical Specifications
Completed in 2023, the Beijing Daxing Anding Circular Economy Park Leachate Project addresses the rigorous demands of managing toxic landfill leachate. Landfill leachate contains complex biochemical cocktails featuring high concentrations of heavy metals, organic acids, chlorides, and volatile ammonia that rapidly degrade ordinary concrete or welded steel structures. To guarantee long-term containment integrity, Center Enamel supplied high-capacity Glass-Fused-to-Steel (GFS) tanks:
● Application Area: Landfill Leachate Management
● Project Location: Beijing, China
● Tank Configuration: 16.82m x 23.4m (H), 2 sets
● Total Tank Volume: 10,392 m3
Advanced Engineering for Hazardous Leachate Containment
Center Enamel's GFS tanks combine the high tensile strength of structural steel with the complete chemical inertia of porcelain glass. Fused at extreme temperatures ranging from 820C to 930C, the inorganic molecular bond provides vital performance advantages:
● Absolute Corrosion Resistance: The smooth, vitreous enamel surface withstands severe pH fluctuations (standard pH 3–11, special pH 1–14) and aggressive chemical exposure without sub-film corrosion.
● Rigorous Quality Assurance: Every individual steel panel undergoes a 1500V high-voltage holiday test prior to dispatch to ensure zero pinhole defects and absolute containment security.
● Modular Bolted Erection: Prefabricated bolted modules enable rapid on-site assembly without hazardous field welding, shortening project delivery schedules for critical municipal infrastructure.
Comparative Matrix: Leachate Storage Technologies
Evaluation Parameter | Center Enamel Glass-Fused-to-Steel (GFS) Tanks | Cast-in-Place Concrete Basins | Traditional Welded Carbon Steel Tanks |
Corrosion & Chemical Resistance | Permanent high-temperature glass-steel fusion resists organic acids, salts, and leachate toxins | Vulnerable to concrete carbonation, acid etching, and structural micro-cracking | High susceptibility to interior oxidation, pitting, and coating delamination |
Installation Speed & Modularity | Rapid modular bolted assembly completed safely with minimal heavy equipment | Extremely slow civil construction requiring extensive formwork and curing cycles | Slow field construction requiring complex manual welding and site coatings |
Maintenance Requirements | Minimal; smooth non-porous glass lining prevents sludge accumulation and requires no recoating | High; requires frequent secondary liners, crack injection, and waterproofing repairs | High; requires recurring abrasive blasting and protective repainting |
Frequently Asked Questions (FAQ)
Q: What was the scope of Center Enamel's contribution to the Beijing Daxing Anding Circular Economy Park?
A: Center Enamel supplied two massive Glass-Fused-to-Steel tanks measuring 16.82m x 23.4m (H), providing a combined total storage volume of 10,392 m3 for leachate treatment, completed in 2023.
Q: Why are GFS tanks ideal for landfill leachate containment?
A: Landfill leachate is an aggressive chemical liquid. GFS tanks feature an inorganic glass-steel fusion bond that is completely impermeable, highly resistant to acids and salts, and engineered for a 30+ year service life.
Q: Do Center Enamel's tanks comply with international standards?
A: Yes, Center Enamel manufactures its storage tanks in strict compliance with globally recognized benchmarks, including AWWA D103-09, ISO 28765, and NSF/ANSI 61.
Q: How does modular bolted construction benefit municipal waste projects?
A: Modular bolted construction eliminates the need for hazardous on-site welding, allows precise factory quality control, and drastically accelerates construction timelines compared to traditional concrete or welded alternatives.
