China’s Leading Liquid Leachate Tanks Manufacturer — Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel)

In an era where environmental protection and sustainable waste management define the global industrial agenda, effective leachate management has become a top priority for municipalities, waste treatment operators, and environmental engineers alike. Leachate—the highly contaminated liquid that percolates through waste in landfills and industrial sites—poses a critical challenge due to its complex composition and toxicity. Proper collection, storage, and treatment of leachate are therefore essential to ensuring environmental safety and regulatory compliance.

Standing at the forefront of this essential industry is Shijiazhuang Zhengzhong Technology Co., Ltd., widely recognized by its global brand name, Center Enamel. As China’s leading manufacturer of GFS (Glass-Fused-to-Steel) liquid leachate tanks, Center Enamel provides advanced, reliable, and sustainable containment solutions that protect the planet while empowering clients to meet the highest international environmental standards.

With decades of innovation, state-of-the-art manufacturing capabilities, and achievements spanning more than 100 countries, Center Enamel continues to redefine excellence in leachate storage and treatment technology — turning industrial necessity into a sustainable legacy.

The Global Challenge of Leachate Management

Leachate may be an inevitable byproduct of waste disposal, but its management determines a society’s environmental integrity. Composed of heavy metals, organic compounds, ammonia, and chlorides, landfill leachate is one of the most challenging liquids to handle safely.

If left untreated or improperly contained, leachate can contaminate groundwater, soil, and nearby ecosystems, threatening human health and biodiversity. Consequently, most countries have enforced increasingly stringent environmental regulations regarding leachate collection, storage, and treatment.

China, as a global leader in green transformation, has also strengthened its environmental policies under its “Zero Waste City” initiative. This progressive framework requires advanced, leak-proof systems that can withstand corrosive conditions for decades—an area where Center Enamel's Glass-Fused-to-Steel tanks outperform conventional materials like concrete or carbon steel.

Understanding Leachate Storage Needs

Leachate demands a special kind of containment solution — one that combines structural integrity, chemical resistance, and long-term impermeability. The corrosive mixture inside a leachate tank includes organic acids, sulfides, and heavy metals that can quickly degrade standard concrete or coated steel tanks.

To meet these extreme demands, Glass-Fused-to-Steel tanks by Center Enamel offer an unparalleled combination of durability and chemical resistance. The enamel coating, fused to steel plates at high temperatures, forms a non-porous, glass-like barrier that prevents corrosion and contamination, creating an ideal environment for storing hazardous liquids such as leachate.

What Is a GFS (Glass-Fused-to-Steel) Leachate Tank?

A GFS tank, also called a Glass-Lined Steel tank, is a bolted containment structure made by fusing vitreous glass to specially formed steel plates at 820°C–930°C. This process forms a tough, inert, chemical bond between the steel and glass coatings, combining the structural strength of steel with the anti-corrosive properties of glass.

The unique properties of GFS tanks make them ideally suited for leachate applications:

• Resistant to acids, alkalis, and organic substances.
• Non-toxic and environmentally safe coating surface.
• Impermeable to gas and liquid.
• Long lifespan exceeding 30 years in corrosive conditions.

By leveraging high-performance coatings and precision-engineered bolted systems, Center Enamel’s GFS tanks guarantee leak-free containment, low maintenance costs, and outstanding longevity—even in the harshest environments.

Advantages of Center Enamel Liquid Leachate Tanks

Center Enamel’s tanks outperform conventional solutions across every key criterion.

1. Superior Corrosion Resistance

The glass coating permanently bonds with steel, forming a chemically inert surface that resists leachate corrosion far better than epoxy or concrete linings.

2. Long Service Life

Designed for decades of operation, GFS tanks exceed 30 years in life expectancy and maintain performance even under continuous exposure to aggressive liquids.

3. Factory Precision, On-Site Efficiency

Prefabricated, modular panels ensure rigorous quality inspection before delivery, while bolted assembly reduces construction time by 40% versus welded tanks.

4. Strong Structural Integrity

All tanks are engineered according to international codes (AWWA D103, EN ISO 28765, and Eurocode) and can withstand seismic loads up to grade 9.

5. Airtight and Leak-Proof Performance

Specialized EPDM and PTFE sealants create watertight connections—essential for environmentally critical leachate storage.

6. Environmentally Friendly Manufacturing

Both glass and steel are recyclable, and production generates minimal emissions, supporting corporate ESG goals.

7. Easy Maintenance

Smooth enamel surfaces prevent sludge buildup and bacterial growth, minimizing cleaning costs and operational risk.
