Center Enamel Successfully Supplies Glass-Fused-to-Steel Wastewater Tanks for Food Wastewater Project in the Democratic Republic of Congo
With the rapid growth of food processing industries worldwide, the demand for efficient and environmentally responsible wastewater treatment systems continues to increase. Food wastewater, often characterized by high organic content, variable flow rates, and complex chemical compositions, requires durable and corrosion-resistant storage and treatment infrastructure.
Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), a global leader in Glass-Fused-to-Steel (GFS) tank technology, has once again demonstrated its engineering strength by successfully delivering GFS wastewater tanks for a Food Wastewater Project in the Democratic Republic of Congo. The project was completed in January 2026, with construction fully finished and the system now fully operational, supporting safe and efficient wastewater treatment for the food industry.
Project Overview: Food Wastewater Treatment in Congo
Project Background
The Democratic Republic of Congo is experiencing steady growth in food processing and agricultural industries. Alongside this growth comes the challenge of managing food wastewater in compliance with environmental regulations and sustainability goals.
The project owner required a high-performance wastewater storage and treatment solution capable of handling food-industry effluent while ensuring long-term reliability in a challenging environment. After careful evaluation, Center Enamel’s Glass-Fused-to-Steel tanks were selected as the optimal solution due to their proven durability, corrosion resistance, and international certifications.

Why Glass-Fused-to-Steel Tanks Are Ideal for Food Wastewater Projects
Addressing the Challenges of Food Wastewater
Food wastewater typically contains:
High organic loads
Grease, fats, and suspended solids
Variable pH levels
Corrosive biological and chemical components
Traditional concrete or coated steel tanks often struggle to maintain long-term performance under these conditions. Glass-Fused-to-Steel tanks provide a superior alternative, offering exceptional resistance to corrosion and abrasion.
Glass-Fused-to-Steel Technology: A Proven Solution
Glass-Fused-to-Steel technology involves fusing a specially formulated glass coating onto steel plates at temperatures of 850–930°C, forming a chemically bonded surface that combines the best properties of both materials.
As China’s first manufacturer to independently develop GFS tanks, Center Enamel has accumulated decades of experience and nearly 200 patented enameling technologies, ensuring consistent quality and superior performance.
Key Advantages of GFS Tanks for Food Wastewater Treatment
1. Outstanding Corrosion Resistance
The glass coating provides a non-reactive, chemically inert surface that resists acids, alkalis, and biological corrosion commonly found in food wastewater environments.
2. Long Service Life
Center Enamel’s GFS tanks are designed for a service life of 30 years or more, reducing replacement frequency and lifecycle costs.
3. Hygienic and Smooth Surface
The smooth glass surface prevents sludge adhesion and microbial buildup, improving treatment efficiency and simplifying cleaning operations.
4. Structural Strength and Reliability
By retaining the mechanical strength of steel, GFS tanks withstand dynamic loads, seismic activity, and temperature fluctuations.
5. Environmentally Sustainable
Glass and steel are recyclable materials, supporting environmentally responsible wastewater management practices.
Engineering Design for the Congo Food Wastewater Project
Optimized Multi-Tank Configuration
The project required wastewater tanks of varying sizes to accommodate different treatment stages. Center Enamel provided:
One φ22.17 × 6.0 m tank for high-capacity wastewater processing
One φ17.58 × 6.0 m tank for secondary treatment or equalization
