As global water scarcity intensifies, desalination infrastructure has become a lifeline for arid regions. In 2025, Center Enamel successfully reinforced Chile’s water security by delivering two massive Fusion Bonded Epoxy (FBE) Tanks equipped with Aluminum Geodesic Dome Roofs. These units provide a combined 6,580 m3 of resilient storage, engineered to withstand the dual challenges of Pacific coastal salinity and Andean seismic activity.
Structured data helps engineers and search engines quickly identify project parameters.
Feature | Specification | Engineering Benefit |

Dimensions | $phi 17m times 14.5m$ (Height) | Optimized footprint for desalination sites. |
Standards | AWWA D103-09, NSF/ANSI 61, NCh 2369 | Global compliance for safety and potable water. |
Coating | Thermal-set Epoxy Powder (Holiday-free) | C5-M rated protection against coastal salt-spray. |
Desalination plants are typically located in high-salinity marine environments. Standard carbon steel tanks often fail within 5–10 years due to salt-air oxidation.
● The Solution: Center Enamel used Fusion Bonded Epoxy (FBE) coating, applied in a controlled factory environment. This high-temperature thermal fusion process creates a "holiday-free" barrier that is chemically inert, providing a 30+ year design life even in aggressive Pacific coastal conditions.
Chile is one of the world's most seismically active zones. Storage tanks must endure lateral forces and liquid sloshing without structural failure.
● The Solution: Our engineers utilized Finite Element Analysis (FEA) to ensure compliance with Chilean Seismic Standard NCh 2369. By reinforcing shell plates and using specialized anchoring systems, the tanks maintain the necessary ductility to absorb tremors.
In arid Chilean climates, water loss to evaporation and contamination by airborne dust or salt spray can negate desalination efficiency.
● The Solution: Each tank is sealed with an Aluminum Geodesic Dome Roof. These roofs are naturally self-healing and corrosion-resistant. Their clear-span design requires no internal support columns, minimizing contact with the purified water and reducing the structure's center of gravity for better seismic performance.
Our FBE bolted tanks integrate seamlessly across the Reverse Osmosis (RO) value chain:
● Pre-treatment Tanks: Protecting raw seawater stages from corrosive attack.
● Brine Storage: Safely containing highly concentrated salt byproducts that would pit standard steel.
● Permeate & Potable Water: Maintaining NSF/ANSI 61 water quality standards for distribution to mining, agricultural, and urban sectors.
Traditional concrete or field-welded tanks face significant hurdles in remote Andean regions. Center Enamel’s modular construction offers:
● 50% Faster Installation: Precision panels are shipped in compact crates and bolted on-site, requiring minimal heavy machinery.
● Factory-Controlled Quality: Unlike field-applied paint, our FBE coating is applied under strict laboratory conditions, ensuring uniform thickness and bond strength.
● Seismic Ductility: Bolted joints allow for slight flexibility, which—combined with our seismic load design—prevents the catastrophic cracking often seen in rigid concrete reservoirs.
● Phase 1: Engineering: Custom seismic and hydraulic modeling.
● Phase 2: Production: CNC fabrication and thermal epoxy bonding.
● Phase 3: Logistics: Secure sea-freight to Chile.
● Phase 4: Assembly: Rapid on-site bolting and dome installation.
● Phase 5: Commissioning: Hydrostatic testing and RO system integration.
Q: Why are FBE tanks preferred over stainless steel for desalination?
A: While stainless steel is excellent, FBE bolted tanks offer a more cost-effective solution for large-volume storage while providing equivalent or superior resistance to specific high-chloride brine environments.
Q: Are these tanks safe for drinking water?
A: Yes. Center Enamel FBE tanks are NSF/ANSI 61 and WRAS certified, ensuring no impurities leach into the potable water supply.
Q: How do Aluminum Domes handle high wind loads?
A: The geodesic design is aerodynamically efficient and inherently strong, capable of resisting wind speeds exceeding 150 km/h while remaining lightweight.
With over 30 years of experience, Shijiazhuang Zhengzhong Technology Co., Ltd is Asia’s leading bolted tank manufacturer. Operating in 100+ countries, we are the first in China to produce GFS tanks and remain a global leader in FBE, Stainless Steel, and Aluminum Dome solutions.
