GFS Leachate Storage Tanks: Advanced Technology and Superior Performance by Center Enamel

GFS Leachate Storage Tanks: Advanced Technology and Superior Performance by Center Enamel

Leachate storage is an essential component of environmental protection in landfill and wastewater management. Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), an industry leader since 2008, offers state-of-the-art Glass-Fused-to-Steel (GFS) leachate storage tanks that provide unparalleled corrosion resistance, durability, and environmental safety.

Understanding Leachate and Its Storage Challenges

Leachate is a highly corrosive liquid generated when water permeates landfill waste, dissolving chemical compounds, heavy metals, and pathogens. It poses serious threats to soil, groundwater, and surrounding ecosystems if leakage occurs.

combine exceptional corrosion resistance, mechanical strength, and hygiene.

As a leading storage tank manufacturer worldwide. Center Enamel can provide Glass Lined Steel(GLS) tanks, fusion bonded epoxy tanks, stainless steel tanks, galvanized steel tanks and aluminum geodesic dome roofs, Wastewater and Biogas Project Equipments for global customers.

WasteWater Treatment Project Equipment Supply

Key challenges for leachate storage tanks include:

• Withstanding harsh chemical environments with pH ranging typically from 3 to 11, and in special cases from 1 to 14
• Preventing leaks and environmental contamination
• Providing robust structural integrity amid large fluid volumes and external stresses
• Ensuring long-term service life and minimizing costly maintenance
• Compliance with stringent environmental and safety regulations worldwide

Traditional options like concrete or carbon steel tanks often face corrosion, structural wear, and high lifecycle costs, while some plastic tanks lack scalability and durability.

What are Glass-Fused-to-Steel (GFS) Tanks?

GFS tanks integrate the superior strength and flexibility of steel with the exceptional corrosion resistance of glass through a unique high-temperature fusion process. Steel plates are coated on both sides with powdered glass and fired at 820°C to 930°C, chemically bonding the glass to the steel surface to form a smooth, glossy, and inert coating.

This fusion provides:

• Outstanding protection against acids, alkalis, salts, solvents, and abrasive materials in leachate
• Hermetic sealing preventing liquid and gas permeation
• Easy-to-clean, low-adhesion surfaces resistant to staining and graffiti
• Color stability with customizable coating colors such as black blue, grey olive, forest green, cobalt blue, desert tan, and others
