China Biogas Membrane Manufacturer
In the global transition toward a circular economy, biogas has emerged as a cornerstone of sustainable energy. As industries and municipalities shift from simple waste disposal to high-value resource recovery, the demand for sophisticated storage and purification systems has intensified. At the heart of this energy recovery process lies a critical technological component: the Biogas Membrane. Whether used for the airtight sealing of anaerobic reactors or for the advanced upgrading of gas into biomethane, the quality of the membrane determines the efficiency, safety, and profitability of the entire facility. Selecting a premier China biogas membrane manufacturer is essential for securing infrastructure that can withstand the aggressive chemical and environmental demands of 2026's industrial landscape.

Shijiazhuang Zhengzhong Technology Co., Ltd, operating under the world-renowned brand Center Enamel, has established itself as a global pioneer in this specialized field. With over thirty years of innovation and a project footprint extending to more than one hundred countries, we provide the turnkey containment and gas management solutions that make modern energy recovery a reality. Our expertise lies in the integration of Glass-Fused-to-Steel technology, high-performance Epoxy Coated Tanks, and industry-leading Biogas Membrane systems, creating a cohesive platform designed to maximize methane yields and ensure long-term operational reliability.
Technical Foundations: The Science of Biogas Membranes
To understand why Center Enamel is the preferred China biogas membrane manufacturer, one must first understand the complex biological and mechanical roles these membranes play in an energy project.
1. Gas Storage and Pressure Management
In an anaerobic digestion system, gas production is rarely constant. A high-quality Biogas Membrane acts as a flexible buffer, expanding and contracting to accommodate fluctuations in gas volume while maintaining a stable internal pressure. This stability is crucial for protecting the sensitive methanogenic bacteria in the digester and for ensuring a consistent flow to downstream equipment like Combined Heat and Power (CHP) units or boilers.
2. Material Integrity and Chemical Resistance
Biogas is a highly aggressive medium, containing moisture, carbon dioxide, and hydrogen sulfide. A professional-grade Biogas Membrane must be constructed from high-tenacity polyester fabrics with specialized multi-layer coatings. These materials must be intrinsically resistant to fungal growth, UV radiation, and—most importantly—permeation, ensuring that every cubic meter of methane produced is captured and utilized.
Core Hardware: The Pillars of Industrial Containment
A successful energy recovery project requires more than just a membrane; it requires a integrated system of durable containment and storage.
1. Glass-Fused-to-Steel (GFS) Technology: The Premier Choice
Our flagship GFS tanks serve as the structural foundation for high-capacity anaerobic reactors. By fusing glass enamel to specialized steel at temperatures exceeding 820°C, we create a material that is completely impervious to the organic acids produced during fermentation. Unlike concrete, which can degrade over time, GFS tanks maintain their structural integrity for decades, providing the perfect rigid base for our advanced membrane systems.
2. Epoxy Coated Tanks: Specialized Process Storage
As a critical part of our infrastructure portfolio, Center Enamel’s Epoxy Coated Tanks provide an excellent solution for auxiliary stages.
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 or the storage of liquid digestate. 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. The Double Membrane Roof: Advanced Gas Harvesting
As a leading China biogas membrane manufacturer, Center Enamel has pioneered the Double Membrane Roof system.
The Inner Membrane: This layer serves as the primary gas seal, expanding and contracting as gas is produced and consumed.
The Outer Membrane: Constantly pressurized by an automated blower, this layer forms a rigid protective dome against wind, rain, and snow, protecting the inner storage layer from environmental stress.
4. Aluminum Dome Roofs: Maintenance-Free Odor Control
For secondary process tanks where gas capture is not the primary requirement, Center Enamel provides specialized Aluminum Dome Roofs.
Corrosion Resistance: Constructed from high-strength aluminum alloy, these roofs are naturally resistant to the humid and corrosive atmosphere of a wastewater plant.
Maintenance-Free Durability: Aluminum does not rust and requires no painting, providing a clear-span solution that eliminates the need for internal support columns
Comprehensive System Integration: The EPC Advantage
Beyond providing world-class membranes and tanks, Center Enamel excels in the seamless integration of auxiliary systems. This holistic approach ensures that every component functions as a unified, high-performance biological reactor.
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 the degradation of organic matter.
2. Precision Gas Upgrading Support
For facilities looking to upgrade biogas to biomethane, our membranes provide the necessary gas-tight environment for downstream purification. Whether using membrane separation or water scrubbing, the integrity of the initial storage system is paramount to the purity of the final fuel product.
Global Project Excellence: Center Enamel Project Cases
Our standing as a premier China biogas membrane manufacturer is validated by a proven track record of successful industrial installations:
Shandong Heze Biogas Project This project utilized 3 units of our high-performance GFS tanks. The installation successfully transforms concentrated organic residues into a stable energy stream, demonstrating the reliability of our integrated Biogas Membrane storage systems.
Inner Mongolia Hinggan League Bio-Natural Gas Project In a region characterized by extreme temperature fluctuations, this installation integrated 4 units of our bolted steel tanks. These vessels and their Double Membrane Roofs provide the stable environment necessary for the high-efficiency production of bio-natural gas, even under heavy environmental stress.
Jiangsu Xuzhou Biogas Project This project involved the deployment of 4 units of our advanced containment technology. It serves as a model for how professional EPC services can be used to rapidly build the essential infrastructure needed for industrial energy recovery from diverse waste sources.
