Center Enamel EPC Contractor provides food-processing wastewater treatment technology to global customers

The global food industry operates under intense pressure to maintain high production standards while meeting increasingly strict environmental regulations. Food-processing wastewater is characterized by high organic loads, variable flow rates, fluctuating acidity levels, and significant concentrations of Fats, Oils, and Grease (FOG). Treating this complex effluent demands specialized food-processing wastewater treatment technology and, crucially, a streamlined delivery model that guarantees performance and minimizes project risk.

Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) transcends the role of a mere equipment supplier; we serve as a reliable EPC Contractor (Engineering, Procurement, and Construction) specializing in end-to-end wastewater solutions for the food and beverage sector. By managing the entire project lifecycle—from initial process design and material selection to on-site construction and commissioning—we provide global customers with the certainty of a single point of responsibility and guaranteed operational success.

Our EPC approach integrates our foundational strength in durable containment, including Glass-Fused-to-Steel (GFS) tanks and Epoxy Coated Steel Tanks, with advanced biological and physical-chemical processes, ensuring every food-processing wastewater treatment technology solution is resilient, sustainable, and optimized for resource recovery.

The EPC Advantage: Streamlining Complex Food-Processing Projects

For food producers facing expansion, regulatory upgrades, or relocation, partnering with an experienced EPC Contractor like Center Enamel offers unparalleled benefits over the traditional multi-vendor approach.

1. Single Point of Responsibility (SPOR)

Risk Mitigation: As a single EPC Contractor, Center Enamel assumes total liability for the project's budget, schedule, and guaranteed performance metrics (such as effluent discharge quality or biogas yield). This eliminates the costly disputes and delays often associated with coordinating multiple independent contractors.

Cost and Time Certainty: We provide a comprehensive, fixed-price contract and a precise timeline, allowing food producers to accurately forecast capital expenditure and minimize the disruption to their core business operations.

2. Integrated Design and Procurement

Process Optimization: Our engineers, specializing in food-processing wastewater treatment technology, design the entire system with material efficiency and operational simplicity in mind, integrating the best available containment and process equipment (including our proprietary GFS tanks) from the outset.

Supply Chain Efficiency: We leverage our global network for procurement, ensuring high-quality, certified equipment is delivered on time, regardless of the project location.

3. Guaranteed Performance and Commissioning

Turnkey Delivery: Our commitment extends beyond construction. As the EPC Contractor, we commission the entire facility, ensuring the food-processing wastewater treatment technology meets all pre-agreed performance indicators before final handover, providing a truly turnkey solution.

Tailored Technology: The Center Enamel Advantage in Containment

Successful food-processing wastewater treatment technology depends on containment that can withstand the corrosive and highly active nature of organic effluents. Center Enamel’s EPC philosophy ensures the selection of the most suitable containment material for every stage of the process.

1. Glass-Fused-to-Steel (GFS) for Core Biological Reactors

GFS tanks are the superior choice for critical, high-load food processing reactors:

High Corrosion Resistance: Food waste (especially fermentation byproducts and cleaning solutions) can be highly corrosive. GFS provides an inert, durable internal surface that is resistant to the organic acids, fats, and variable acidity levels, ensuring decades of service without internal maintenance.

High-Rate Anaerobic Digestion: For converting high-organic food waste into biogas (a core technology), GFS tanks provide the structural integrity and corrosion resistance necessary to house high-power mixing and heating systems under continuous, challenging conditions.

2. Epoxy Coated Steel Tanks for Supportive Infrastructure

For non-critical storage, flow equalization, or lower corrosion risk areas, Epoxy Coated Steel Tanks are specified for cost-effectiveness and rapid deployment:

Buffer and Equalization: These tanks efficiently handle high-volume flow fluctuations before the main treatment process begins. Their fast assembly and reliable coating provide a budget-conscious yet durable solution.

Tertiary Process Containment: Epoxy tanks are ideal for the storage of treated water, chemical dosing solutions, or clean effluent, complementing the high-performance GFS reactors.

3. Advanced Aluminum Dome Roofs for Storage

The integrity of stored water and odor control are essential. Aluminum Dome Roofs are integrated into the EPC design for specific containment units:

Odor Control and Containment: Over primary equalization or high-solids storage tanks, the dome roof provides a permanent, effective seal to capture offensive odors, ensuring compliance with local nuisance regulations.

Clean Water Protection: For the final step in food-processing wastewater treatment technology—the storage of reclaimed water—the aluminum cover acts as a highly effective barrier against external airborne contamination and dust, preserving the purity of the recovered resource.

Core Food-Processing Wastewater Treatment Technology

Our EPC expertise focuses on integrating state-of-the-art processes into our durable containment systems to achieve the twin goals of resource recovery and strict environmental compliance.

1. High-Efficiency Pre-Treatment

Due to the high FOG and solids content in food wastewater, effective pre-treatment is paramount:

FOG Removal: Specialized dissolved air flotation (DAF) or grease separation units are integrated to protect downstream biological reactors from inhibition and clogging.

Sieving and Screening: Automated systems remove large suspended solids that would otherwise increase sludge volume and complicate biological treatment.

2. Biogas Recovery and Energy Independence

The high organic content of food waste makes biogas recovery a key economic component of our EPC Contractor delivery model.

High-Rate Anaerobic Digestion: GFS reactors are utilized for this stage. The captured energy transforms a waste liability into a valuable energy asset.

Double Membrane Roofs for Gas Security: We utilize the Double Membrane Roof as the core biogas storage solution atop the anaerobic digesters. This engineered component:

Safely Stores Methane: Provides a flexible, gas-tight volume to manage variable biogas production, maximizing its use for heat and power generation.

Eliminates Fugitive Emissions: Ensures a sealed system, enhancing safety and environmental performance, critical for an EPC Contractor providing guaranteed performance.

3. Biological Nutrient Removal (BNR)

Advanced food-processing wastewater treatment technology requires rigorous removal of nitrogen and phosphorus to prevent aquatic pollution:

Aerobic and Anoxic Processes: Sequencing Batch Reactors (SBR) or Activated Sludge processes, contained within GFS tanks, are used to biologically convert and remove excess nutrients, ensuring the treated effluent meets stringent discharge standards.
