China Domestic Sewage Treatment Equipment Provider

In the urban landscape of 2026, the management of domestic sewage has transcended basic sanitation to become a cornerstone of the circular economy. As cities expand and environmental regulations for discharge become more rigorous, the demand for decentralized and modular Domestic Sewage Treatment Equipment has reached an all-time high. Effective sewage treatment is not only about protecting public health but also about resource recovery—turning wastewater into reclaimed water and nutrient-rich biosolids.

Shijiazhuang Zhengzhong Technology Co., Ltd, operating under the world-renowned brand Center Enamel, stands at the pinnacle of this industry. As the most experienced China Domestic Sewage Treatment Equipment Provider, we possess over thirty years of technical expertise and a global project footprint covering more than one hundred countries. We specialize in the design, manufacturing, and EPC (Engineering, Procurement, and Construction) of advanced treatment systems that integrate Glass-Fused-to-Steel (GFS) technology, high-performance Epoxy Coated Tanks, and innovative gas and odor management solutions.

Technical Foundations: The Biological Cycle of Sewage Treatment

Domestic sewage consists primarily of greywater (from sinks and showers) and blackwater (from toilets), containing high concentrations of organic matter, pathogens, and nutrients. As a specialized China Domestic Sewage Treatment Equipment Provider, Center Enamel engineers equipment that facilitates the complex biological stages required for purification.

1. Primary and Secondary Treatment Sequences

Modern Domestic Sewage Treatment Equipment utilizes a multi-stage approach to ensure effluent meets strict environmental standards:

Pre-treatment: Removal of large solids and grit to protect downstream mechanical components.

Anaerobic Stage: Utilizing anaerobic microorganisms to break down complex organic loads without the need for aeration, reducing energy consumption.

Aerobic Stage (Activated Sludge/MBBR): Introducing oxygen to allow aerobic bacteria to polish the water, removing remaining BOD (Biochemical Oxygen Demand) and ammonia nitrogen.

2. Modular and Decentralized Solutions

One of the key trends in 2026 is the shift toward decentralized treatment. Center Enamel provides modular, bolted steel equipment that can be rapidly deployed in residential communities, remote resorts, or expanding urban fringes where traditional centralized sewer connections are not feasible.

Core Hardware: Engineering Excellence in Containment

The reliability of a sewage treatment facility is directly tied to the durability of its containment vessels. Center Enamel provides a hardware portfolio engineered to withstand the corrosive nature of domestic wastewater.

1. Glass-Fused-to-Steel (GFS) Tanks

Our GFS tanks are the gold standard for aerobic and anaerobic 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 chemical inertness of glass. These tanks offer superior resistance to the hydrogen sulfide and organic acids inherent in sewage, ensuring a service life that satisfies long-term municipal planning.

2. Epoxy Coated Tanks: Versatile and Durable Support

As a critical part of our infrastructure portfolio, Center Enamel Epoxy Coated Tanks provide an excellent solution for various auxiliary stages in sewage management.

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 organic residues and sewage chemicals.

Versatile Application: These tanks are ideal for equalization, sludge thickening, or the storage of treated reclaimed water. 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.

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

3. Aluminum Dome Roofs: Odor Control and Protection

For sewage treatment plants located near residential areas, odor control is paramount. Center Enamel integrates specialized Aluminum Dome Roofs to provide an airtight and aesthetically pleasing solution.

Natural Corrosion Resistance: Constructed from high-strength aluminum alloy, these roofs are naturally resistant to the humid and corrosive atmosphere of a sewage plant.

Structural Efficiency: The geodesic design allows for wide spans without internal columns, protecting the treatment process from external contaminants while containing volatile odors.

Comprehensive System Integration: The EPC Advantage

Beyond providing world-class tanks, Center Enamel excels as a China Domestic Sewage Treatment Equipment Provider by offering full-service integration for the following processes:

1. MBR (Membrane Bioreactor) Technology

We provide the containment and infrastructure for MBR systems, which combine biological treatment with membrane filtration. This results in ultra-clean effluent suitable for irrigation or industrial reuse, significantly reducing the footprint of the Domestic Sewage Treatment Equipment.

2. Sludge Management and Stabilization

Treating the liquid is only half the battle; the resulting sludge must be stabilized. Our anaerobic digestion tanks and Double Membrane Roof systems allow for the stabilization of sewage sludge, reducing its volume while potentially capturing biogas for onsite energy use.
