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
