1. The Unique Challenge of Disinfecting Water Storage

Storage tanks for disinfected or treated (chlorinated) water face a relentless barrage of chemical and biological assaults. Chlorine, ozone, or other powerful disinfectants can corrode conventional steel, concrete, or epoxy-lined tanks—leading to leaks, contamination, and recurring maintenance.

Moreover, biofilm buildup, microbial formation, and difficult maintenance routines threaten both infrastructure and public health. Modern disinfected water storage tanks must combine absolute corrosion resistance with the ability to withstand chemicals, frequent cleaning, and harsh weather.

2. What Makes GFS the Ideal Tank Technology?

Glass-Fused-to-Steel is a manufacturing process where specially formulated glass enamel is fused to either side of pre-treated steel panels at high temperature (820-930°C). The result is a composite panel whose glass coating is integrally bonded to the steel at a molecular level.

a. Science-Backed Superiority

• Corrosion Resistance: GFS tanks normally withstand pH 3-11 (standard) and, with special coatings, pH 1-14. Resistant even to aggressive chlorine, ozone, acids, and alkalis found in disinfection scenarios.
• Hardness & Durability: With a Mohs hardness of 6, the glass surface resists abrasion and mechanical wear, and provides a service life of 30+ years.
• Gas & Liquid Impermeability: GFS coating prevents vapor or fluid migration, avoiding both gross leaks and micro-contamination.
• Non-Porous & Hygienic: The glass finish is smooth, glossy, and anti-adhesive, eliminating sites for biofilm formation, bacteria, or algae.
• Quick Cleaning: Smooth surfaces allow efficient high-pressure or chemical cleaning—key for disinfected or high-purity water storage.
• No Repainting: While steel or concrete tanks require re-lining or re-painting, GFS tanks maintain their integrity for decades with little to no cosmetic maintenance.

b. Structural Brilliance

• GFS tanks are constructed modularly from bolted panels, each independently inspected, enabling rapid, scalable erection on-site and ease of repair, modification, or future expansion
• Wall thicknesses range from 3mm–12mm, and tank diameters and heights are fully customizable.
• Full range of roof types, manways, access points, fittings, ladders, platforms, nozzles, and automation controls can be tailored as needed.

3. Manufacturing Excellence at Center Enamel

• Plate Preparation: Highest-quality steel (up to 20mm thick) is shot-blasted and cleaned prior to enameling.
• Double-Side Enameling: Each plate is coated both inside and out and fired at up to 900°C, producing a ~0.3–0.45mm enamel thickness that resists even high-concentration disinfectants.
• Panel Formation: Precision laser cutting, bending, and drilling allow for exact fit and structural integrity.
• Assembly: Bolted panels are sealed with continuous flexible (often silicone) sealant, ensuring 100% water and gas tightness.
• Accessories and Inspection: All connections and accessories are surface-treated for corrosion immunity; panels are tested rigorously for coating adhesion and electrical continuity.

4. GFS vs. Traditional Tank Technologies

5. Applications of GFS Disinfecting Water Tanks

• Municipal Water Storage: Chlorinated potable water tanks for city distribution.
• Drinking Water Reservoirs: Secure storage for disinfected water at treatment plants or remote communities.
• Industrial Water: Storage of process water requiring periodic chemical disinfection.
• Food and Beverage Plants: Ultra-clean water storage meeting food safety standards.
• Healthcare: Hospitals, clinics, and pharmaceutical facilities demanding highest hygienic standards.
• Emergency & Disaster: Mobile/reservoir tanks for safe supply during emergency events.

6. Certifications and Environmental Standards

Center Enamel GFS tanks are manufactured and certified to meet:

• ISO9001, NSF/ANSI 61 for potable water
• AWWA D103-09, EN1090, WRAS, FM, LFGB for design, quality, and water safety
• Site-specific and user-requested hygienic or corrosion performance standards.

7. Case Studies: Center Enamel Worldwide

• Urban Water Facilities in Africa: Installed GFS tanks serving municipal water plants where chlorine concentrations challenge conventional tanks.
• Pharmaceuticals & Food Processing: Multinational beverage and pharma companies rely on GFS for ultra-clean storage of treated process or ingredient water.
• Disaster Relief: Rapid deployment of modular GFS tanks to store disinfected water in natural disaster zones, improving resilience of water supply.

8. Environmental and Economic Advantages

• Minimized Life-cycle Costs: No need for regular re-lining or painting translates to less downtime and fewer operational expenses.
• Reduced Waste: Fewer refurbishments and longer lifespans mean less construction waste and environmental impact.
• Green Construction: Fully recyclable steel and inert glass support responsible resource management.
