China Integrated Sewage Treatment Equipment Supplier

In the complex landscape of 2026, the global industrial and municipal sectors face an unprecedented challenge: balancing rapid development with increasingly stringent environmental regulations. As water scarcity becomes a primary strategic concern, the demand for highly efficient, modular, and reliable integrated sewage treatment equipment has surged. Unlike traditional, fragmented wastewater systems that require extensive on-site civil engineering and lengthy construction timelines, integrated solutions offer a "plug-and-play" approach to environmental compliance. Selecting a premier China integrated sewage treatment equipment supplier is no longer just a procurement decision—it is a strategic partnership that determines the operational resilience and sustainability of a facility.

Shijiazhuang Zhengzhong Technology Co., Ltd, operating under the brand Center Enamel, stands as the foremost leader in this field. With over thirty years of technical excellence and projects deployed in more than one hundred countries, we provide the turnkey infrastructure that makes decentralized and industrial water recovery a reality. Our expertise lies in the seamless fusion of advanced biological processes with world-class containment technology, including Glass-Fused-to-Steel (GFS) reactors, high-performance Epoxy Coated Tanks, and innovative Double Membrane Roofs.

Technical Foundations: The Architecture of Integrated Treatment

To be recognized as a top-tier China integrated sewage treatment equipment supplier, a manufacturer must master the integration of diverse biological and mechanical processes within a compact, modular footprint.

1. The Biological Core: AO, MBR, and MBBR Processes

Modern integrated sewage treatment equipment typically utilizes advanced biological pathways to remove Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and nutrients such as nitrogen and phosphorus.

AO Process (Anaerobic-Oxic): A foundational process that alternates between anaerobic and aerobic zones to achieve high nitrogen removal efficiency.

MBR (Membrane Bioreactor): Combines biological treatment with membrane filtration, producing high-quality effluent suitable for direct reuse.

MBBR (Moving Bed Biofilm Reactor): Utilizes specialized plastic carriers to increase the surface area for microbial growth, allowing for a more compact reactor design.

2. Modular Efficiency and Rapid Deployment

The hallmark of Center Enamel’s integrated systems is their modularity. By pre-fabricating the primary components—including reactors, filtration units, and control systems—in a factory-controlled environment, we reduce on-site construction time by more than half. This "factory-to-site" model ensures consistent quality and minimizes project risk.

Core Hardware: The Pillars of Integrated Infrastructure

The reliability of integrated sewage treatment equipment is determined by the quality of its containment vessels and covering systems. Center Enamel provides a specialized hardware portfolio engineered for longevity and chemical resistance.

1. Glass-Fused-to-Steel (GFS) Tanks: The Premium Reactor

Our GFS tanks are the global benchmark for core biological reactors. By fusing high-tech glass enamel to specialized steel at temperatures exceeding 820°C, we create a material that combines the structural strength of steel with the extreme chemical inertness of glass. These tanks are virtually impervious to the aggressive organic acids and corrosive environments found in concentrated sewage, ensuring a service life that satisfies the most demanding project requirements.

2. Epoxy Coated Tanks: Versatile Process Support

As a critical part of our infrastructure portfolio, Center Enamel’s Epoxy Coated Tanks provide an excellent solution for various auxiliary stages within an integrated treatment plant.

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 chemicals and sewage residues.

Versatile Application: These tanks are ideal for equalization, storage of treated effluent, or as buffer tanks for incoming sewage. They offer a cost-effective yet highly durable alternative where high corrosion resistance is essential, ensuring the entire facility maintains a consistent standard of quality.

Precision Manufacturing: Every tank is manufactured under strict conditions to ensure consistent coating thickness and superior bond strength, providing a reliable long-term storage solution for industrial environments.

3. Double Membrane Roof: Energy and Odor Management

For integrated systems utilizing anaerobic stages, the Double Membrane Roof is an essential component for gas harvesting and environmental protection.

Pressure Control: The system features an inner membrane for gas storage and a pressurized outer membrane for structural protection. This ensures that the reactor maintains a consistent internal pressure, protecting the biological process while capturing biogas for energy recovery.

Environmental Integrity: The gas-tight seal prevents the release of methane and offensive odors, a critical requirement for facilities located near residential or commercial areas.

4. Aluminum Dome Roofs: Maintenance-Free Durability

To provide long-term protection for aeration basins and clarifiers, Center Enamel offers specialized Aluminum Dome Roofs .

Corrosion Resistance: Constructed from high-strength aluminum alloy, these roofs are naturally resistant to the humid and corrosive atmospheres typical of sewage treatment.

Structural Efficiency: The geodesic design requires no internal support columns, allowing for the unobstructed operation of internal equipment such as mixers and scrapers.

Comprehensive System Integration: The EPC Advantage

As a comprehensive China integrated sewage treatment equipment supplier, Center Enamel excels in the seamless integration of auxiliary systems. This holistic approach ensures that every component—from mixing to sludge handling—functions as a unified, high-performance system.

1. Advanced Mixing and Agitation

To prevent sedimentation and ensure optimal microbial contact, we integrate high-efficiency mixing systems. These are designed to maintain a homogeneous environment within our Epoxy Coated Tanks and GFS reactors, preventing the formation of dead zones and maximizing treatment efficiency.

2. Intelligent Control and Automation

Our integrated sewage treatment equipment is equipped with advanced automation and remote monitoring systems. This allows operators to track water quality parameters in real-time and adjust process settings remotely, ensuring consistent compliance with discharge standards while minimizing manual labor costs.

3. Integrated Pre-treatment and Sludge Management

A true integrated solution must address the entire treatment train. Our systems include mechanical screens to remove large debris and sludge dewatering units to reduce the volume of residual waste, significantly lowering disposal costs for the end-user.

Global Project Excellence: Center Enamel Project Cases

Our standing as a premier China integrated sewage treatment equipment supplier is validated by a proven track record of successful industrial and municipal installations:

Hebei Cangzhou Industrial Wastewater Project Supporting the regional drive for environmental protection, Center Enamel provided 13 units of tanks for this significant industrial initiative. These vessels serve as the backbone for a large-scale integrated treatment network, demonstrating our capacity to manage high-volume industrial waste.

Sichuan Brewing Wastewater Treatment Project This project utilized 6 units of our high-performance GFS tanks. The installation highlights our expertise in providing integrated solutions for high-strength organic wastewater, ensuring stable biological performance and efficient water recovery for the food and beverage industry.

Ghana Domestic Sewage Treatment Project Demonstrating our global reach, this project involved the deployment of specialized integrated sewage treatment equipment to treat municipal effluent. It serves as a model for how modular, factory-prefabricated systems can provide immediate environmental benefits in developing regions.
