Center Enamel: Delivering Professional Anaerobic/Aerobic EPC Turnkey for the Wastewater Treatment Package
The industrial landscape of 2026 is defined by a rigorous commitment to environmental stewardship and resource efficiency. As discharge standards for Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and total nitrogen become increasingly stringent, the reliance on single-stage treatment methods has become obsolete. For facilities ranging from food processing plants to large-scale municipal utilities, the most effective path toward compliance and sustainability lies in the hybrid biological approach. By utilizing an Anaerobic/Aerobic EPC Turnkey model, organizations can benefit from a unified engineering vision that combines the energy-recovering power of anaerobic digestion with the precision polishing of aerobic treatment.
Shijiazhuang Zhengzhong Technology Co., Ltd, operating under the world-renowned brand Center Enamel, stands as a global leader in providing the specialized engineering infrastructure necessary for this transition. With over thirty years of innovation and a project footprint extending to more than one hundred countries, we provide the essential containment and processing solutions that make a sophisticated Wastewater Treatment Package a reality. Our expertise lies in the integration of Glass-Fused-to-Steel (GFS) technology, high-performance Epoxy Coated Tanks, and advanced gas management systems, creating a cohesive platform designed to maximize pollutant removal while minimizing operational overhead.
The Technical Synergy of Anaerobic and Aerobic Processes
A professional Anaerobic/Aerobic EPC Turnkey solution is designed to leverage the distinct biological strengths of different microbial communities. This hybrid approach is particularly effective for high-strength industrial effluents where a single process would be either too energy-intensive or biologically unstable.
1. Phase I: Anaerobic Pre-treatment and Energy Capture
The anaerobic stage is the "heavy lifter" of the Wastewater Treatment Package. In a controlled environment without oxygen, anaerobic bacteria break down high concentrations of organic pollutants.
COD/BOD Reduction: This stage can remove 60% to 80% of the organic load, significantly reducing the burden on downstream systems.
Biogas Valorization: The methane produced during digestion is a renewable energy source that can be used to heat process water or generate electricity, turning a treatment liability into an energy asset.
Low Sludge Yield: Anaerobic processes produce significantly less biological sludge compared to aerobic systems, reducing disposal costs.
2. Phase II: Aerobic Polishing and Nutrient Removal
The aerobic stage acts as the final refinery. By introducing controlled aeration, aerobic microorganisms further degrade remaining organic matter and specialized bacteria perform nitrification and denitrification.
Effluent Quality: Ensures the final water meets or exceeds strict regulatory standards for discharge into surface waters.
Odor Control: Aerobic processes are highly effective at eliminating the sulfur-related odors often associated with untreated organic waste.
Nutrient Stabilization: This stage is critical for removing phosphorus and nitrogen, preventing eutrophication in receiving water bodies.
Core Infrastructure: GFS and Epoxy Coated Tank Solutions
A successful Wastewater Treatment Package requires containment that can handle the aggressive chemical nature of raw effluent as well as the mechanical demands of high-rate aeration.
1. Glass-Fused-to-Steel (GFS) Technology: The Premier Choice
Our flagship GFS tanks are the global benchmark for both anaerobic reactors and aerobic aeration basins. By fusing glass enamel to specialized steel at temperatures exceeding 800°C, we create a material with unparalleled properties:
Superior Chemical Resistance: The glass interior is completely impervious to the organic acids, alkalis, and salts common in industrial wastewater.
Operational Longevity: With a service life exceeding 30 years, GFS tanks provide a much higher return on investment than concrete or welded steel.
Modular Construction: The bolted design allows for rapid installation, which is critical for facilities that cannot afford long periods of operational downtime.
2. Epoxy Coated Tanks: High-Performance Industrial Storage
As a critical part of our infrastructure portfolio, Center Enamel’s Epoxy Coated Tanks provide an excellent solution for various auxiliary stages of the treatment train.
Advanced Coating Technology: Our epoxy tanks utilize a high-specification electrostatic powder coating process. This results in a smooth, durable finish that provides excellent resistance against a wide range of industrial cleaning agents and process fluids.
Versatile Application: These tanks are ideal for equalization, storage of treated effluent, or as sludge thickening vessels. They offer a cost-effective yet highly durable alternative where high corrosion resistance is essential.
3. Aluminum Dome Roofs: Maintenance-Free Protection
For aeration basins and secondary clarifiers where gas capture is not the primary requirement, Center Enamel provides specialized Aluminum Dome Roofs . These geodesic structures provide essential odor control and prevent rainwater from diluting the treated stream, all without the need for internal support columns or frequent repainting.
Advanced Gas Management: Double Membrane Roofs
In the anaerobic phase of the Wastewater Treatment Package, capturing the produced biogas is essential for environmental safety and energy recovery. Center Enamel’s Double Membrane Roofs are engineered as a dynamic, integrated gas management solution.
1. Dual-Layer Pressure Control
The system uses an inner membrane for gas storage and a constantly pressurized outer membrane for structural protection. This ensures that the anaerobic reactor maintains a consistent internal pressure, protecting the biological process and the tank structure from mechanical stress.
2. Durability and Safety
Our membranes are UV-stabilized and chemically resistant, ensuring they can withstand the aggressive vapors found in industrial wastewater environments while providing an airtight seal for methane capture.
Sustainability and Economic ROI for Industry
Investing in an Anaerobic/Aerobic EPC Turnkey solution from Center Enamel is a strategic business decision:
Energy Savings: Reducing the COD load anaerobically drastically lowers the energy required for the oxygen-intensive aerobic stage.
Resource Recovery: The system allows for the reclamation of biogas for energy and treated water for non-potable industrial reuse.
Future-Proofing: Modular tanks can be easily expanded as the facility's production capacity grows, ensuring the treatment infrastructure scales with the business.
