Shijiazhuang Zhengzhong Technology Co., Ltd., known internationally as Center Enamel, has been a pioneer in providing advanced epoxy coated tanks for global storage solutions . As China’s first manufacturer to design and produce epoxy coated tanks, Center Enamel has built an international reputation for excellence, innovation, and commitment to environmental sustainability. Our tanks meet and exceed certifications such as NSF, ISO, FDA, LFGB, BSCI, and WRAS, ensuring global compliance and trustworthiness. With advanced production capabilities and rich industry expertise, Center Enamel serves more than 100 countries and regions, providing dependable storage tanks for biogas storage, wastewater treatment, potable water, chemicals, agriculture, and food industries.
As part of our global environmental mission, Center Enamel is now delivering epoxy coated tanks for biogas storage projects in Bahrain, marking another milestone in sustainable energy infrastructure in the Middle East. Bahrain's growing focus on biogas as a renewable energy source perfectly aligns with our technology, helping the country reduce emissions, recover valuable energy, and promote circular economy principles.
Epoxy coated tanks are a specialized type of bolted steel tank that uses a high-performance epoxy resin coating as a protective lining on the interior and/or exterior steel surfaces. The epoxy coating creates a barrier that protects the tank from corrosion, chemical attacks, and microbial degradation—issues that are common in biogas environments.
For biogas storage, especially in tropical and arid environments like Bahrain, these tanks offer multiple technical and operational advantages:
Excellent Corrosion Resistance: The aggressive conditions created by anaerobic digestion—including hydrogen sulfide (H₂S), carbon dioxide (CO₂), and organic acids—can quickly degrade unprotected steel. Epoxy coatings provide an inert barrier that significantly increases the life of the tank.
Leak Prevention and Gas Tightness: The smooth interior surface of epoxy coatings prevents gas leakage and helps ensure gas-tight performance, which is essential for safe and efficient biogas storage.
Fast and Modular Installation: Unlike welded steel tanks, epoxy coated tanks are assembled onsite using a bolted design, which simplifies installation and reduces construction timelines—especially useful in remote or rural Bahrain regions.
Customizable Volumes and Designs: We tailor every tank to meet specific biogas plant requirements in Bahrain, whether integrated with anaerobic digesters or serving as standalone gas holders.
By combining modular construction with high-grade anti-corrosive protection, epoxy coated tanks have become the gold standard for cost-effective, long-lasting biogas storage solutions in both developed and developing economies.
The biogas industry in Bahrain is emerging as a strategic pillar in the kingdom’s efforts to diversify its energy mix and improve waste management systems. As a small but ambitious island nation in the Arabian Gulf, Bahrain is increasingly adopting biogas technology to convert organic waste—such as livestock manure, food scraps, and municipal sludge—into clean, renewable energy.
Energy Diversification: Biogas serves as a complementary energy source to traditional oil and gas, aligning with Bahrain’s Vision economic diversification plan.
Agricultural Waste Utilization: The livestock sector in Bahrain produces significant quantities of organic waste, making it a prime candidate for anaerobic digestion and biogas recovery.
Wastewater Management Improvements: Several wastewater treatment plants in Bahrain are adopting anaerobic processes that benefit from reliable epoxy coated tanks for digestate and gas storage.
In these projects, the tank system must perform under pressure, resist gas attack, and offer operational flexibility. Center Enamel’s epoxy coated tanks excel in all these aspects and are now being integrated into Bahrain’s biogas infrastructure.
Center Enamel stands out as the leading epoxy coated tanks manufacturer not only in China but also in the international storage solutions market. Our extensive experience, high-precision manufacturing, and globally certified products make us the ideal partner for biogas storage projects in challenging environments like Bahrain.
We operate under ISO 9001 quality management systems, with all products undergoing strict quality control at every stage of production—from steel selection and surface treatment to coating application and tank assembly.
Certifications: NSF, ISO, LFGB, WRAS, FDA, BSCI
Advanced Testing: Adhesion, porosity, coating thickness, and salt-spray tests ensure superior epoxy performance.
Our epoxy coated tanks are not one-size-fits-all. Every project in Bahrain benefits from our custom engineering services, including:
Design Adaptability: Tanks can be engineered to handle high-pressure gas or integrate with gas holders and digesters.
Capacity Flexibility: Volumes range from tens of cubic meters to tens of thousands of cubic meters or more depending on biogas storage requirements.
With over 30 years of experience and hundreds of global installations, we’ve delivered storage solutions for clients in:
Middle East: Saudi Arabia, UAE, Oman, and now Bahrain
Southeast Asia: Indonesia, Philippines, Vietnam
Europe and Africa: Germany, Kenya, South Africa
Our tanks are used in municipal biogas plants, agricultural digesters, and industrial anaerobic systems, offering consistently high performance under diverse conditions.
The collaboration between Bahrain’s renewable energy sector and Center Enamel’s epoxy coated tank technology signifies a transformative shift toward sustainable energy practices in the Gulf region. As the demand for biogas storage grows in response to climate goals, food-energy-water security, and smart waste management, our tanks provide the infrastructure backbone to make this green transition possible.
Integrated Biogas Hubs: Combining livestock waste, municipal sludge, and food waste to generate community-scale energy systems.
Hybrid Tank Systems: Pairing epoxy coated tanks with double membrane gas holders, flare systems, and CHP units.
Public-Private Partnerships: Working with Bahraini energy authorities, agricultural cooperatives, and environmental consultants to expand reach.
At Center Enamel, we don’t just deliver tanks—we deliver reliable energy storage infrastructure tailored for long-term environmental and economic impact.
