The Role of Water Purification Tanks

Water purifying tanks hold water that has been treated to remove impurities, pathogens, and contaminants to meet strict quality standards. These tanks are part of post-treatment storage or intermediate buffer systems in ultrafiltration, reverse osmosis, UV treatment, and typical purification workflows.

Key requirements of water purifying tanks include:

• Preserving ultra-pure water quality without deterioration.
• Preventing contamination and microbial growth.
• Enduring exposure to aggressive chemicals or additives used in water treatment.
• Maintaining liquid integrity under varying pressure, temperature, and environmental conditions.
• Compliance with international hygiene and safety standards.

Why Glass-Fused-to-Steel (GFS) Technology is Ideal

GFS tanks are constructed from steel panels coated inside and outside with a uniform vitreous glass enamel layer fired at high temperatures (820°C to 930°C). This fusing process forms a permanent, chemically bonded glass coating that provides a smooth, inert, corrosion-resistant, and robust surface critical for maintaining purified water quality.

Advantages of GFS for water purification tanks include:

• Advanced corrosion resistance to acids, alkalis, salts, and oxidizers common in water purification processes.
• Non-porous, non-leaching surface preventing metal ion release or biological contamination.
• High mechanical strength and flexibility from the steel substrate allowing large tank volumes and pressure loads.
• Ease of cleaning and hygiene maintenance with a smooth, glossy, and inert glass surface.
• Long service life exceeding 30 years with nearly zero maintenance and no repainting.
• Modular bolted panel construction enabling quick onsite assembly and scalability.
• Compliance with NSF/ANSI 61, ISO 9001, AWWA D103-09, WRAS, FM, and other global certifications.

Technical Features and Manufacturing Excellence

• Premium Steel Plates: Hot-rolled steel plates (3-12 mm thickness) are surface-prepared meticulously to remove oxides and contaminants before enameling.
• Dual-Side Enamel Coating: Both the internal and external surfaces are coated with 0.25-0.45 mm thick glass enamel layers.
• Kiln Fusion: Plates are fired in high-temperature kilns (~850°C) under controlled atmospheres to achieve uniform fusion and strong adhesion.
• Bolted Tank Assembly: Precisely fabricated panels are fastened with corrosion-resistant bolts and silicone seals engineered for leak-tightness and thermal expansion accommodation.
• Quality Control: Tanks undergo rigorous testing for coating thickness, adhesion strength (>3450 N/cm²), chemical resistance, impermeability, hardness (Mohs 6), and sparking test (>1500V).
• Customization: Tank size and configuration tailored to process needs with options like insulation, stirring devices, instrumentation ports, and specialized coatings for extreme water chemistries.

Applications of GFS Water Purifying Tanks

• Municipal Water Treatment Plants: Storage of purified potable water ensuring compliance with drinking water standards.
• Pharmaceutical Industry: Preparation and storage of USP-grade purified water for manufacturing.
• Food and Beverage Production: High-purity water storage for beverage formulations and process hygiene.
• Semiconductor and Electronics Manufacturing: Critical storage of ultrapure water with zero contamination risk.
• Laboratory and Research: Sterile and contamination-free water storage to preserve experimental integrity.
• Power Plants: Storage of RO or demineralized water used in boiler feed or cooling.
