Center Enamel Delivers GFS Tank Solutions for Peru Food Processing Wastewater Project
In December 2025, Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd.) finalized the second phase of a major food processing wastewater treatment project in Peru. This multi-phase infrastructure project stands as a benchmark for industrial environmental compliance, utilizing Center Enamel’s signature Glass-Fused-to-Steel (GFS) technology to manage the complex organic loads, fats, and solids inherent in food processing.
Fully operational as of early 2026, the facility utilizes a comprehensive integrated tank system to handle wastewater treatment, anaerobic digestion, clarification, and process water storage.

Why Glass-Fused-to-Steel (GFS) for Food Processing?
Food processing wastewater is uniquely challenging; it is characterized by fluctuating pH levels, high fat/oil content, and high biological oxygen demand (BOD). Center Enamel’s GFS technology provides the necessary engineering resilience through a unique manufacturing process where glass and steel are fused at 820°C–930°C.
Key Advantages for the Peru Facility:
● Hygienic & Inert: The glass-fused surface is chemically inert and non-porous. This prevents sludge adhesion, biofilm formation, and microbial growth, which is critical for maintaining hygiene standards in a food processing environment.
● Superior Corrosion Resistance: The fusion process creates a durable barrier against the aggressive acidic environments often found in anaerobic digesters and industrial wastewater tanks.
● Rapid Expandability: As demonstrated by the transition from Phase I to Phase II, the bolted modular design allowed the client to scale their treatment capacity without the need for traditional, slow-curing concrete construction.
● Operational Longevity: With a design life exceeding 30 years, GFS tanks provide a lower Total Cost of Ownership (TCO) compared to standard welded or concrete tanks, which require frequent repainting or structural repairs.
Compliance and International Standards
For international projects of this scale, regulatory compliance is the ultimate trust signal. Center Enamel manufactured these tanks in strict adherence to globally recognized engineering benchmarks:
Engineering Standards Met:
● AWWA D103-09: Standard for Bolted Steel Tanks for Water Storage.
● NSF/ANSI 61: Essential safety standard for materials in contact with potable water.
● ISO 28765 / EN 1090: Quality standards for glass-fused-to-steel coatings and structural steel components.
Supporting Sustainable Development in Peru
The Peru project exemplifies how Center Enamel helps industrial clients bridge the gap between production growth and environmental responsibility. By integrating anaerobic digestion into the wastewater workflow, the facility can effectively treat high-organic wastewater while potentially recovering energy, aligning with global trends in sustainable food processing.
With installations in over 100 countries, Center Enamel continues to serve as a specialized partner for food and beverage giants, municipal water authorities, and industrial conglomerates requiring robust, code-compliant storage solutions.
Frequently Asked Questions (FAQ)
Q: Why was GFS technology chosen over concrete for this project?
A: GFS tanks offer a non-porous surface that concrete cannot match. In food processing, hygiene is paramount; concrete surfaces can harbor bacteria in microscopic cracks, whereas the inert, glass-fused surface of GFS tanks is easily cleaned and prevents contamination.
Q: How does the bolted design handle the high-pressure loads of an anaerobic digester?
A: Center Enamel’s bolted tanks are engineered specifically to meet structural load standards (AWWA D103). The panels are designed with high-strength steel and high-grade sealants to ensure the tank structure remains rigid and leak-proof even under the pressure cycles of an active digester.
Q: How long did the expansion process take for Phase II?
A: A key advantage of the bolted design is construction speed. Because the panels are prefabricated in the factory, on-site assembly is significantly faster than field-welding or pouring concrete, allowing the Peru facility to expand its processing capacity with minimal downtime.
