Philippines Water Purification Project: Center Enamel GFS Tank Case Study
In 2019, Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd) successfully completed the Philippines Water Purification Project, a vital infrastructure initiative designed to enhance water safety and availability in a region facing rapid urbanization. The project, executed in two phases, utilized advanced Glass-Fused-to-Steel (GFS) technology—the industry standard for long-term, corrosion-resistant liquid storage.
Project Technical Specifications
The project utilized modular GFS technology to ensure precise capacity management across two distinct implementation phases.
Phase | Tank Dimensions (Dia × H) | Capacity |
Phase 1 | 9.93m × 12.0m | 928 m³ |
Phase 1 | 9.17m × 7.8m | 515 m³ |
Phase 1 | 7.64m × 6.0m | 275 m³ |
Phase 2 | 9.93m × 12.0m | 928 m³ |
Phase 2 | 7.64m × 6.0m | 275 m³ |
Why GFS Technology for Water Purification?
Water purification plants require containment systems that are not only durable but chemically inert to prevent water contamination. Center Enamel’s GFS tanks were selected for this project due to their specialized material composition.
1. Superior Corrosion Resistance
The Philippines' tropical climate—characterized by high humidity, intense heat, and high rainfall—is notoriously difficult for traditional carbon steel or concrete storage tanks. The GFS process fuses glass enamel to a steel core at temperatures over 800°C. This results in a surface that is:
● Chemically Inert: Preventing any leaching into the purified water supply.
● Non-Porous: Resisting the accumulation of scale, biofilm, and bacteria.
2. Structural Integrity & Longevity
GFS tanks are engineered for a 30+ year service life. The modular design allows for structural flexibility, ensuring the tanks can withstand the environmental stressors of the region, such as seismic activity and monsoon-level precipitation, while maintaining their structural shape and seal integrity.
3. Hygienic Roof Protection
Each tank in the Philippines project was equipped with a GFS roof. This ensures a "closed-loop" storage system, preventing external contamination from dust, debris, insects, or wildlife, which is a critical requirement for maintaining water purification standards.
Benefits for Municipal Infrastructure
The success of the Philippines Water Purification Project highlights the advantages of choosing modular GFS storage over traditional civil engineering methods (like cast-in-place concrete):
● Compliance: The tanks adhere to stringent international quality standards, including ISO 9001 and NSF/ANSI 61 (for potable water contact).
● Speed of Deployment: Modular bolted construction significantly reduces on-site labor and construction timelines compared to traditional concrete basins.
● Operational Reliability: With over 30 years of industry experience and installations in more than 100 countries, Center Enamel’s GFS tanks require minimal maintenance, ensuring consistent water distribution for local communities.
Frequently Asked Questions (FAQ)
Q: Why is GFS preferred for water purification over concrete?
A: Concrete tanks often develop cracks over time due to ground settling or thermal expansion, which can lead to leaks and contamination. GFS tanks are flexible and feature a factory-applied, glass-lined surface that is inherently resistant to environmental degradation and easier to sanitize.
Q: Are GFS tanks suitable for all climates?
A: Yes. GFS tanks are highly effective in tropical environments like the Philippines, where high humidity causes traditional steel to rust quickly. The fused glass-enamel layer acts as a barrier, preventing oxidation entirely.
Q: What is the significance of the GFS roof in this project?
A: The roof is essential for "Potable Water Integrity." By enclosing the tank, the GFS roof prevents evaporation and eliminates the risk of airborne pollutants entering the purified water supply before it is distributed to the community.
The Philippines Water Purification Project stands as a benchmark for municipal water infrastructure. By leveraging Center Enamel’s proven Glass-Fused-to-Steel technology, the region has secured a reliable, long-term solution for purified water storage. This project reaffirms Center Enamel's commitment to supporting global public health initiatives through innovative, durable, and sustainable storage engineering.
