China Biological Wastewater Treatment Processes Contractor
In the strategic environmental landscape of 2026, the global community faces a pivotal mandate: the transformation of wastewater into a sustainable asset. As urban populations surge and industrial zones intensify, the reliance on traditional chemical treatment is being superseded by more efficient, nature-inspired Biological Wastewater Treatment Processes. These systems utilize specialized microorganisms to degrade organic pollutants, offering a path to high-purity effluent and renewable energy recovery.

Shijiazhuang Zhengzhong Technology Co., Ltd, known globally as Center Enamel, stands at the pinnacle of this sector. As the most trusted China Biological Wastewater Treatment Processes Contractor, we bring over thirty years of material science expertise and a project portfolio spanning more than one hundred countries. By integrating world-class Glass-Fused-to-Steel (GFS) reactors, high-performance Epoxy Coated Tanks, and advanced gas management systems, we provide turnkey EPC (Engineering, Procurement, and Construction) solutions that define the future of water resilience.
Technical Foundations: Mastering the Living Engine of Water Treatment
As a comprehensive China Biological Wastewater Treatment Processes Contractor, Center Enamel focuses on the precision engineering required to maintain stable microbial environments. Biological Wastewater Treatment Processes are divided into two primary categories, each requiring specialized containment and mechanical support.
1. Anaerobic Biological Processes: The Energy Engine
For high-strength organic waste, anaerobic digestion is the preferred process. In this oxygen-free environment, microorganisms break down complex matter through a sequence of hydrolysis, acidogenesis, acetogenesis, and methanogenesis.
IC (Internal Circulation) Reactors: Utilizing multi-level circulation to maximize contact between sludge and wastewater, ideal for high-load industrial applications.
CSTR (Continuous Stirred Tank Reactor): Ensuring a completely mixed environment for consistent degradation of solids, such as kitchen waste or livestock manure.
USR (Upflow Sludge Blanket Reactor): An efficient method that combines physical and biological processes to treat high-strength organic loads with minimal sludge production.
2. Aerobic Biological Processes: The Polishing Heart
Aerobic systems utilize oxygen-dependent bacteria to further purify wastewater, typically following an anaerobic stage or as a standalone municipal solution.
MBBR (Moving Bed Biofilm Reactor): Incorporating plastic carrier media within our tanks to provide an expansive surface area for microbial growth.
SBR (Sequencing Batch Reactor): A time-controlled process that integrates aeration and sedimentation in a single vessel, offering unmatched modular scalability.
MBR (Membrane Bioreactor): Combining biological degradation with ultra-fine membrane filtration to produce water suitable for direct industrial reuse.
Core Hardware: Engineering Resilience for Biological Reactors
The operational success of any Biological Wastewater Treatment Processes project is fundamentally tied to the reliability of its containment infrastructure. Center Enamel provides a hardware portfolio engineered for the harshest biochemical environments.
1. Glass-Fused-to-Steel (GFS) Tanks
Our flagship 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 chemical inertness of glass.
Biochemical Immunity: GFS is virtually impervious to the organic acids and hydrogen sulfide produced during anaerobic digestion.
Modular Assembly: The bolted design allows for fast on-site installation, which is critical for meeting the rapid construction timelines required in 2026.
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 organic residues and treated liquid effluent.
Versatile Application: These tanks are ideal for equalization, sludge thickening, or the storage of treated 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: Maintenance-Free Protection
To shield the treatment process and contain offensive odors, Center Enamel integrates specialized Aluminum Dome Roofs .
Odor Containment: These geodesic structures provide a superior seal, containing volatile organic compounds (VOCs) and protecting the local environment.
Structural Excellence: Constructed from high-strength aluminum alloy, these roofs are naturally resistant to the humid and corrosive atmosphere of a biological treatment plant and require no internal support columns.
The EPC Advantage: Integrating Waste-to-Energy
As a premier China Biological Wastewater Treatment Processes Contractor, Center Enamel emphasizes the recovery of resources from the treatment train.
1. Biogas Harvesting with Double Membrane Roofs
In anaerobic stages, capturing methane is vital for energy neutrality. Our Double Membrane Roof systems feature an inner gas-holding membrane and a pressurized outer protective membrane. This ensures zero methane leakage and allows the facility to recover biogas for use in CHP (Combined Heat and Power) units.
2. Precision Aeration and Mixing
For aerobic systems, we integrate high-efficiency fine-bubble diffusers and intelligent control systems. This ensures optimal oxygen transfer, which is the most energy-intensive component of the process, thereby reducing operational costs.
Global Project Excellence: Center Enamel Project Cases
Our standing as a leading China Biological Wastewater Treatment Processes Contractor is validated by a proven track record of successful installations:
Sichuan Brewing Wastewater Treatment Project This project utilized 6 units of our high-performance GFS tanks. The installation highlights our expertise in treating high-strength organic wastewater from a major beverage producer, ensuring stable biological performance and efficient gas recovery.
Hebei Cangzhou Industrial Wastewater Project Supporting regional environmental protection, Center Enamel provided 13 units of tanks for this significant initiative. These vessels serve as the backbone for a large-scale integrated treatment network, handling complex waste profiles from diverse industrial sources.
Shantou Urban Sewage Treatment Project This significant municipal initiative utilized our advanced containment technology to create a beautiful and ecological environment. The project effectively manages high volumes of domestic sewage using high-efficiency biological principles.
Muyuan Group Breeding Wastewater Projects Across various locations in Hunan, Henan, and Heilongjiang, we have deployed multiple high-capacity units (typically 2 units per site) for managing massive volumes of high-load animal waste. These projects demonstrate our ability to deliver integrated biological solutions that ensure asset integrity even in extreme climates.
