Center Enamel — China’s Leading Beverage Wastewater Tank Manufacturer
The beverage industry thrives on purity, precision, and sustainability. From soft drinks and breweries to dairy plants and juice processors, beverage manufacturers depend heavily on water — not only as a primary ingredient but also as a critical resource in cleaning, bottling, cooling, and equipment sterilization. Yet, with high water usage comes an equally high responsibility: treating and managing beverage wastewater efficiently and sustainably.
Behind every successful beverage brand’s commitment to environmental compliance lies reliable wastewater treatment infrastructure. At the center of this critical infrastructure are wastewater storage and treatment tanks — engineered containment systems that ensure wastewater from beverage operations is collected, stabilized, and treated before safe discharge or reuse.
As an industry leader with over three decades of engineering innovation, Shijiazhuang Zhengzhong Technology Co., Ltd., globally known as Center Enamel, has become the trusted name for beverage wastewater tanks in China and worldwide. With cutting-edge Glass-Fused-to-Steel (GFS) technology, Center Enamel provides advanced, corrosion-resistant storage solutions that meet the beverage industry’s stringent sanitary and environmental standards.
1. The Challenge of Beverage Wastewater
Beverage production is one of the most water-intensive industries in manufacturing. An average beverage plant uses between 3 to 10 liters of water to produce a single liter of product. This usage results in significant volumes of wastewater rich in organic matter, sugars, acids, detergents, and residual product solids.
Such wastewater, if left untreated, can lead to:
· High biochemical oxygen demand (BOD) and chemical oxygen demand (COD) levels, depleting oxygen in receiving waters.
· Increased total suspended solids (TSS) and nutrients (like nitrogen and phosphorus) causing eutrophication.
· Strong odor and bacterial growth, affecting nearby environments.
· Regulatory non-compliance leading to operational and reputational risks.
Therefore, beverage manufacturers require high-performance wastewater containment systems—able to resist corrosion, safely store acidic or alkaline wash water, and seamlessly integrate with biological or physicochemical treatment systems.
2. Center Enamel — Engineering Excellence Since 2008
Founded in 2008, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) was the first company in China to produce Glass-Fused-to-Steel tanks. Over 35 years later, the company has grown to become Asia’s leading GFS tank manufacturer and one of the most trusted names globally in bolted steel storage solutions.
Highlights of Center Enamel’s global leadership:
· 150,000 m² production facility equipped with CNC cutting, enameling furnaces, and robotic assembly systems.

Center Enamel’s success blends scientific precision, strict quality control, and a mission to engineer sustainable environments worldwide.
3. The Essence of GFS (Glass-Fused-to-Steel) Technology
The secret of Center Enamel’s enduring success lies in its proprietary Glass-Fused-to-Steel (GFS) technology — also known as Glass-Lined Steel (GLS).
During manufacturing, specially selected low-carbon steel is coated with high-quality glass powder (vitreous enamel) and fused at temperatures between 820°C–930°C. This fusion chemically binds the two materials, resulting in an ultra-hard, corrosion-resistant composite that offers the best characteristics of both.
Major advantages of GFS technology include:
· Corrosion Resistance: Unaffected by acidic or alkaline liquids, detergents, or organic acids found in beverage wastewater.
· Longevity: Service life exceeding 30 years without repainting or recoating.
· Impermeability: Completely gas and liquid tight for odor control.
· Hygienic Surface: Smooth, inert, non-stick surface that prevents microbial growth — ideal for sanitary industries.
· pH Stability: Reliable performance across the full pH range (1–14).
· Quick Installation: Modular bolted panels assembled on-site without welding, allowing fast project delivery.
· Eco-Friendly: 100% recyclable materials with VOC-free coatings and low carbon manufacturing processes.
Thanks to this innovation, Center Enamel’s GFS tanks are the global standard for beverage wastewater containment in breweries, distilleries, dairies, and soft drink bottling facilities.
4. Applications in Beverage Industry Wastewater Treatment
Center Enamel’s tanks are designed to meet complex requirements across the beverage manufacturing process, handling everything from chemical rinse water to high-strength organic effluent.
Typical applications include:
· Wastewater Equalization Tanks: Collect and balance flow fluctuations from production lines and CIP systems.
· Anaerobic and Aerobic Reactors: Enable biological digestion to reduce organic load (COD/BOD) and generate biogas.
· Sludge Holding Tanks: Safely store concentrated biosolids before dewatering or composting.
· pH Adjustment Tanks: Used in neutralization processes for acidic or alkaline effluents.
· Clean-in-Place (CIP) Waste Storage Tanks: Contain acidic and caustic cleaning solutions before reuse or treatment.
· Final Effluent Tanks: Hold treated water for reuse in utilities, irrigation, or safe discharge.
Whether for beer, wine, dairy, fruit juice, or water bottling plants, Center Enamel customizes each tank to the facility’s chemical, thermal, and operational challenges.
5. Why Leading Beverage Companies Choose Center Enamel
1. Corrosion Resistance for Diverse Effluents
Cleaning-in-place (CIP) operations generate wastewater with varying acidity and chemical residues. GFS coatings eliminate corrosion risk even in extreme pH or detergent-rich environments, outlasting concrete or epoxy coatings.
2. Long-Term Cost Efficiency
With a design lifespan exceeding 30 years, GFS tanks minimize maintenance costs, downtime, and replacements, providing the lowest long-term cost of ownership.
3. Airtight, Odor-Free Operation
Bolted connections sealed with industrial-grade EPDM or PTFE gaskets ensure leakproof performance and odor containment for sensitive food production areas.
4. Rapid Installation and Project Flexibility
Modular designs enable tank construction in tight urban or plant spaces without hot work or large-radius cranes, reducing installation time by up to 40%.
5. Hygienic Surface for Food Safety
Non-porous enamel interiors resist buildup of organic material, ensuring tanks stay sanitary and easier to clean — meeting HACCP and GMP standards in beverage manufacturing.
