Center Enamel Delivers Comprehensive Glass-Fused-to-Steel Tank Solutions for Canada Dairy Wastewater Treatment Project
Wastewater management is a core environmental responsibility for industries worldwide, especially for the dairy sector, which generates high-strength wastewater rich in organic load, fats, solids, and nutrients. As sustainability and regulatory compliance become increasingly critical, modern dairy operations require reliable, durable, and efficient wastewater storage and treatment infrastructure. In 2025, Center Enamel—one of the world’s leading tank engineering companies—successfully supplied a full set of Glass-Fused-to-Steel (GFS) tanks for a large-scale dairy wastewater treatment project in Canada. The project was officially completed in November 2025 and is now fully operational, reinforcing Center Enamel’s global reputation as a preferred provider of industrial wastewater storage solutions.
With decades of expertise and projects across more than 90 countries, Center Enamel continues to advance wastewater treatment infrastructure with its high-quality GFS tanks. The Canada dairy wastewater treatment project represents another milestone in delivering sustainable, high-performance, and long-service-life tank systems for demanding industrial environments.
1. Project Overview: A Complete GFS Tank Package for Dairy Wastewater Treatment
The Canada dairy wastewater treatment project required a highly optimized tank system capable of managing various phases of the wastewater treatment process—including aeration, equalization, clarification, sludge storage, flocculation, and flotation. The engineering requirements called for multiple tanks with different configurations, heights, diameters, and roofing systems to meet specific treatment functions.

2. Why GFS Tanks Were Selected for This Project
The dairy industry produces wastewater with high chemical oxygen demand (COD), biological oxygen demand (BOD), suspended solids (TSS), nitrogen, phosphorus, and fats/oils/grease (FOG). These characteristics require tanks that offer outstanding corrosion resistance, long service life, and structural stability. After an in-depth evaluation of available technologies, the project stakeholders selected Center Enamel’s Glass-Fused-to-Steel (GFS) tanks due to their superior performance and long-term cost efficiency.
Key Reasons for Selecting GFS Tanks
High resistance to corrosion, ideal for industrial wastewater
Fast installation, reducing project timelines
Modular design, suitable for remote or cold-weather environments
Long service life, often exceeding 30 years
Low maintenance requirements
Compliance with multiple international standards
Strong structural integrity for tall or large-volume tanks
Excellent performance in cold climates, a critical factor for Canada
These advantages align perfectly with the operational needs of a dairy wastewater treatment facility, where robust and leak-free tanks are essential for process stability and long-term efficiency.
3. Advantages of Center Enamel’s GFS Tank Technology
Glass-Fused-to-Steel is considered one of the world’s best tank materials for harsh wastewater environments. This advanced composite material combines the strength of steel with the corrosion resistance of glass. During production, two or more layers of specially formulated glass coatings are fused to the steel substrate at temperatures above 850°C, creating a chemical and physical bond that is exceptionally durable.
3.1. Unmatched Corrosion Resistance
The GFS material provides protection against:
High-strength dairy wastewater
Acids produced during biological treatment
Corrosive gases such as hydrogen sulfide
Chemical cleaning agents
Temperature fluctuations and freeze-thaw cycles
This protective coating prevents rusting, peeling, and degradation, ensuring the tank’s structural integrity over decades of use.
3.2. Fast and Efficient Installation
All tank components are pre-fabricated and shipped to the site, allowing rapid assembly using a jacking system. Benefits include:
Reduced construction costs
Shorter on-site installation time
Minimal environmental disruption
Ability to assemble tanks year-round, even in cold climates
This was particularly advantageous for a project located in Canada, where seasonal weather challenges can cause delays for traditional construction methods.
3.3. Superior Structural Strength
The steel substrate provides excellent mechanical strength, allowing tanks to withstand large hydrostatic loads and external environmental pressures. This ensures the tanks remain structurally stable over long periods, even under constant operation in a demanding wastewater environment.
3.4. Long Service Life with Minimal Maintenance
Unlike concrete or carbon steel tanks that require frequent maintenance and recoating, GFS tanks maintain peak performance with minimal upkeep. This long-term stability significantly reduces operational costs.
3.5. Full Compliance With International Standards
Center Enamel’s GFS tanks meet or exceed:
ISO 28765 standards for vitreous enamel bolted tanks
AWWA D103 standards for bolted steel water storage tanks
NSF/ANSI standards for potable water and liquid containment
EN/BS international design and safety codes
These certifications guarantee long-term reliability and quality.
4. Engineering Design of the Canada Dairy Wastewater Tank System
Each tank in this project plays a unique and essential role in the wastewater treatment process. The tank system was engineered based on hydraulic calculations, treatment load projections, environmental conditions, and expected long-term operational requirements.
4.1. Aeration Basin Tanks (2 Sets, Ø18.34 × 9 m)
These large open-roof tanks perform the crucial function of biological treatment. Oxygen is supplied to support microbial degradation of organic contaminants.
Key design considerations:
Large diameter to maximize aeration efficiency
Open roof for safe gas release
Durable GFS interior to withstand high oxygen and microbial activity
Strong structural design to accommodate continuous mixing and aeration systems
4.2. Clarifier Tank (Ø12.23 × 4.8 m)
The clarifier enables solids settling and separation from treated effluent.
Features:

4.3. Equalization Tank (Ø10.7 × 9.6 m)
This tank stabilizes flow and regulates influent variations from dairy operations.
Benefits:
Balances peak flows
Ensures consistent downstream processing
Excellent corrosion resistance against varying wastewater composition
4.4. Selector Silo (Ø5.35 × 10.8 m)
The selector tank enhances biological treatment performance by controlling microbial populations.
4.5. Sludge Storage Tank (Ø4.59 × 9.6 m, GFS Roof)
Designed for safe and odor-controlled storage of biological sludge prior to disposal or further processing.
4.6. FLOC and Float Tanks (Both SS304 Roof)
These smaller tanks support chemical and physical treatment processes essential for dairy wastewater.
Why SS304 roofs?
