China Sewage Treatment Plant Equipment Manufacturer
In the global environmental landscape of 2026, the sewage treatment plant (STP) has evolved from a mandatory sanitation facility into a sophisticated center for resource recovery. As urbanization intensifies and environmental mandates become increasingly stringent, the reliability of a facility depends entirely on the quality of its mechanical and structural components. For municipal planners and industrial developers, the choice of a China Sewage Treatment Plant Equipment Manufacturer is a strategic decision that influences operational efficiency, energy consumption, and lifecycle costs for decades.
Shijiazhuang Zhengzhong Technology Co., Ltd, known globally as Center Enamel, stands at the pinnacle of this sector. With over thirty years of innovation and projects spanning more than one hundred countries, we provide the turnkey Sewage Treatment Plant Equipment required to manage complex liquid waste streams. Our core competitive advantage lies in our proprietary Glass-Fused-to-Steel (GFS) technology, high-performance Epoxy Coated Tanks, and integrated process equipment designed for the circular economy.
Technical Foundation: The Architecture of Modern Sewage Treatment
A high-performance sewage treatment plant is a symphony of biological, chemical, and physical processes. As a leading China Sewage Treatment Plant Equipment Manufacturer, Center Enamel focuses on providing the essential hardware for every stage of this treatment train.
1. Primary Treatment and Pre-treatment Equipment
Before biological treatment can begin, physical contaminants must be removed. Our equipment portfolio includes:
Mechanical Bar Screens: For the removal of large debris to protect downstream pumps and mixers.
Equalization Basins: Utilizing our bolted steel tanks to stabilize flow rates and organic loads, ensuring a consistent feed to the biological reactors.
Solid-Liquid Separators: Essential for removing grit and primary solids, reducing the burden on the biological stages.
2. Secondary Biological Treatment: The "Living Heart"
The secondary stage is where organic pollutants are degraded by microorganisms. Center Enamel provides the core reactor vessels for:
Activated Sludge Processes: Our tanks serve as high-efficiency aeration basins, providing the structural resilience needed for continuous oxygen injection.
Anaerobic Digestion: We specialize in high-rate reactors like the CSTR (Continuous Stirred Tank Reactor) and IC (Internal Circulation) systems, which convert organic loads into renewable biogas.
Core Infrastructure: Engineering Resilience for Containment
The most critical component of any Sewage Treatment Plant Equipment set is the containment vessel. The harsh chemical environment of sewage requires materials that are immune to corrosion and structural fatigue.
1. Glass-Fused-to-Steel (GFS) Tanks
Our flagship GFS tanks are the global benchmark for sewage treatment reactors. By fusing high-tech glass enamel to specialized steel at temperatures exceeding 820°C, we create a material that combines the strength of steel with the chemical inertness of glass.
Corrosion Resistance: GFS is impervious to the hydrogen sulfide and organic acids inherent in domestic and industrial sewage.
Rapid Deployment: The modular bolted design allows for fast on-site assembly, which is critical for meeting the tight construction timelines of 2026 urban projects.
2. Epoxy Coated Tanks: Specialized Process Support
As a vital part of our infrastructure portfolio, Center Enamel Epoxy Coated Tanks provide an excellent solution for various auxiliary and storage stages within the 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 organic residues and industrial chemicals.
Versatile Application: These tanks are ideal for the storage of treated liquid effluent, sludge thickening, 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.
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 for aggressive environments.
3. Aluminum Dome Roofs: Maintenance-Free Protection
For the storage of treated water or sludge where gas capture is not the primary requirement, Center Enamel provides specialized Aluminum Dome Roofs .
Self-Supporting Structure: These geodesic domes require no internal columns, maximizing the internal volume for equipment like mud scrapers and mixers.
Longevity: Constructed from high-strength aluminum alloy, they are naturally resistant to the humid and corrosive atmosphere of a wastewater plant, requiring minimal maintenance.
Advanced Sludge and Gas Management Systems
As a comprehensive China Sewage Treatment Plant Equipment Manufacturer, we recognize that modern STPs must manage solids and gases with the same precision as liquids.
1. Sewage Sludge Treatment Equipment
Stabilizing and reducing the volume of sludge is essential for lowering disposal costs. Our equipment includes:
Screw Sludge Dewatering Machines: Providing high-efficiency separation to transform liquid sludge into a stable "cake."
Sludge Thickening Tanks: Utilizing our Epoxy Coated Tanks to increase the solids concentration before digestion or disposal.
2. Biogas Management and Energy Recovery
For facilities utilizing anaerobic digestion, we provide the Biogas Management hardware required to capture energy:
Double Membrane Roofs: Featuring an inner gas-holding membrane and a pressurized outer membrane to ensure zero methane leakage and precise pressure regulation.
Integrated Gas Holders: Storing captured biogas for use in CHP (Combined Heat and Power) units, helping the plant move toward energy neutrality.
