Glass Fused-to-Steel Anaerobic Digestion Tanks for Industrial Wastewater Treatment: A Sustainable, High-Performance Solution

In an era when sustainable industrial practices and efficient wastewater treatment are more crucial than ever, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) leads the way with our Glass Fused-to-Steel (GFS) Anaerobic Digestion Tanks. Engineered with over 30 years of experience and state-of-the-art GFS technology, our tanks offer a robust, reliable, and eco-friendly solution tailored to the challenges of industrial wastewater treatment and biogas production.

At Center Enamel, our aluminum geodesic dome roofs are designed to meet international standards and offer superior protection against the elements, as well as corrosive substances and harsh weather conditions. These roofs are particularly beneficial for tanks storing oil, gas, water, chemicals, and other valuable or sensitive materials.

Unmatched Durability and Corrosion Resistance

Our GFS Anaerobic Digestion Tanks are manufactured by fusing a layer of high-quality glass enamel onto specially pretreated steel plates at temperatures exceeding 850°C. This process creates a smooth, non-porous surface that:

Delivers Exceptional Corrosion Resistance: The dual-layer enamel coating (0.25–0.40 mm thick with an adhesion of 3,450 N/cm) protects the steel from the aggressive chemicals and acidic or alkaline conditions often encountered in industrial effluent. This ensures a service life of over 30 years with minimal maintenance.

Ensures Structural Integrity: The glass fused-to-steel method guarantees that the tanks maintain their integrity under harsh environmental conditions—essential for long-term operation in demanding wastewater treatment applications.

Optimized Design for Efficient Anaerobic Digestion

The design of our anaerobic digestion tanks has been meticulously optimized to support efficient biological reactions. Key features include:

Modular Bolted Construction: The pre-engineered, modular panels enable rapid on-site assembly and offer flexibility for future expansion. This design minimizes installation time and labor costs while allowing customization to meet varying process capacities—from as small as 20 m³ up to 60,000 m³.

Smooth, Easy-to-Clean Interior: The non-porous glass enamel lining not only resists corrosion but also prevents the accumulation of sludge and organic build-up, thereby enhancing the efficiency of biogas production and simplifying routine maintenance.

Environmental and Economic Advantages

Our Glass Fused-to-Steel Anaerobic Digestion Tanks are more than just storage units—they are a strategic investment in sustainable industrial wastewater management. Benefits include:

Renewable Energy Production: Through the anaerobic digestion process, organic contaminants in wastewater are converted into biogas—a renewable energy source that can help offset operational costs and reduce carbon footprints.

Reduced Sludge Generation: The efficient digestion process minimizes sludge production, lowering disposal costs and environmental impact.

Cost-Effective Lifecycle: With low maintenance requirements and a durable design, our tanks reduce long-term operational expenses and offer an excellent return on investment.

Scalability and Customization: Whether for municipal sewage treatment, industrial processing, or agricultural wastewater management, our tanks can be tailored in size, roof design (options include glass fused-to-steel roofs, aluminum trough deck roofs, geodesic dome roofs, or double membrane roofs), and color to perfectly match your facility’s requirements.
