Center Enamel Supplies Glass-Fused-to-Steel Tanks for South Africa Industrial Wastewater Treatment Project
As industries worldwide strive to improve environmental performance and comply with increasingly stringent wastewater regulations, the demand for durable, efficient, and sustainable wastewater treatment solutions continues to grow. Industrial wastewater, in particular, is often more challenging to manage than municipal wastewater due to its higher concentrations of chemicals, organic matter, and variability in flow.
Recognizing these challenges, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel)—a global leader in Glass-Fused-to-Steel (GFS) tank technology—has once again demonstrated its expertise by successfully supplying a series of wastewater tanks for the South Africa Industrial Wastewater Treatment Project.
Completed in August 2025, this project is now fully operational, showcasing Center Enamel’s ability to deliver tailored tank solutions that meet complex industrial requirements while supporting sustainable development goals.
Project Overview
The South Africa Industrial Wastewater Treatment Project was designed to enhance wastewater treatment capacity for a local industrial facility, ensuring compliance with environmental regulations and supporting water reuse initiatives.
Project Specifications:
Application: Wastewater tanks for industrial treatment
Project Location: South Africa
Tank Supply:
Buffer Tank: φ4.58m × 4.2m, 1 set
Equalisation Tank: φ10.7m × 3.6m, 1 set
Calamity Tank: φ13.75m × 5.4m, 1 set
EGSB Tank: φ7.64m × 14.4m, 1 set
Sludge Tank: φ4.58m × 4.2m, 1 set
Completion: August 2025, with construction completed and the project now fully operational
The tanks, fabricated using Glass-Fused-to-Steel technology, were customized to serve different functions within the wastewater treatment process, ensuring reliable performance for each stage of operation.
Role of Each Tank
Buffer Tank (φ4.58m × 4.2m)
Designed to stabilize flow rates and prevent sudden hydraulic surges, ensuring a balanced wastewater stream enters the treatment system.
Equalisation Tank (φ10.7m × 3.6m)
Equalizes variations in pollutant concentrations, flow volume, and temperature, creating steady conditions for downstream treatment processes.
Calamity Tank (φ13.75m × 5.4m)
Functions as an emergency holding tank, providing a safeguard in the event of sudden inflows, operational disruptions, or system failures.
EGSB Tank (φ7.64m × 14.4m)
Serves as the core Expanded Granular Sludge Bed reactor, where anaerobic treatment reduces organic load and generates biogas as a renewable energy source.
Sludge Tank (φ4.58m × 4.2m)
Provides safe and efficient storage for sludge produced during the wastewater treatment process, enabling further processing and disposal.
Together, these tanks form a comprehensive and integrated solution for industrial wastewater treatment, tailored to meet the specific requirements of the South African facility.
Advantages of Glass-Fused-to-Steel Technology
For industrial wastewater projects, the choice of tank material is critical. Industrial effluent often contains corrosive chemicals that quickly degrade conventional concrete or epoxy-coated steel tanks.
Center Enamel’s Glass-Fused-to-Steel tanks were selected for this project due to their unique benefits:
Superior Corrosion Resistance: Inert glass coating protects steel against aggressive chemicals.
Extended Service Life: Proven lifespan of more than 30 years.
Low Maintenance: No need for frequent recoating or structural repairs.
Fast Installation: Prefabricated modular design enables rapid on-site assembly.
Environmental Sustainability: 100% recyclable, energy-efficient production, and minimal on-site disruption.
Compliance with International Standards: Certified under AWWA D103, OSHA, EN ISO 28765, NSF/ANSI 61, and more.
These advantages made GFS tanks the optimal solution for the South Africa Industrial Wastewater Treatment Project, where durability, efficiency, and reliability are non-negotiable.
Project Execution
The project was delivered through a systematic process that ensured efficiency and quality:
Customized Design: Each tank was engineered to suit its specific application and site requirements.
Precision Fabrication: All panels were produced in Center Enamel’s advanced manufacturing base under strict ISO9001 quality standards.
On-Site Assembly: Prefabricated tank panels were shipped to South Africa and assembled using hydraulic jacking equipment, minimizing construction time.
Rigorous Testing: Tanks underwent hydrostatic and leakage tests to confirm integrity and performance before commissioning.
By August 2025, all tanks were successfully installed, tested, and put into operation, ensuring seamless integration into the industrial wastewater treatment system.
Supporting Industrial Sustainability in South Africa
South Africa faces growing challenges in balancing industrial growth with environmental protection. Water scarcity, pollution concerns, and increasing regulatory requirements demand advanced wastewater treatment infrastructure.
The completion of this project supports South Africa’s goals by:
Ensuring Regulatory Compliance: Tanks provide reliable performance in treating high-strength industrial effluent.
Promoting Water Reuse: Treated wastewater can be reused in industrial processes or for irrigation, reducing freshwater demand.
Generating Renewable Energy: The EGSB tank facilitates biogas production, supporting energy recovery and carbon reduction.
Enhancing Long-Term Sustainability: Durable tanks minimize future replacement needs and reduce overall environmental impact.
This project exemplifies how Center Enamel’s technology contributes to sustainable industrial development while protecting vital water resources.
