Center Enamel: Global Leader in UASB Anaerobic Reactors with Glass-Fused-to-Steel Tanks
Wastewater management is one of the most pressing challenges in today’s industrial and municipal sectors. With the rise of population density, urbanization, and industrial activity, wastewater treatment systems must be efficient, reliable, and environmentally sustainable. Among the most effective solutions for high-strength industrial and municipal wastewater is the Upflow Anaerobic Sludge Blanket (UASB) reactor. When combined with advanced tank technologies, such as Glass-Fused-to-Steel (GFS) tanks, UASB reactors can achieve high treatment efficiency, structural durability, and long-term operational stability.
Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) has established itself as China’s leading manufacturer of Glass-Fused-to-Steel tanks and a global provider of wastewater treatment solutions. Leveraging decades of expertise, advanced manufacturing capabilities, and international certifications, Center Enamel delivers UASB anaerobic reactors that combine cutting-edge treatment performance with long-lasting structural reliability.
This article explores the technological advantages, engineering excellence, global applications, and sustainability benefits of Center Enamel’s UASB reactors with GFS tanks.

Center Enamel’s success is founded on nearly 200 patented technologies, a dedicated R&D team, and a manufacturing base covering over 150,000 square meters, equipped with modern fabrication, coating, and inspection facilities.
Why Glass-Fused-to-Steel Tanks for UASB Reactors?
UASB anaerobic reactors are designed to treat high-strength wastewater by facilitating anaerobic digestion in a sludge blanket. The success of a UASB system depends on both biological efficiency and the integrity of the containment tank. Center Enamel’s GFS tanks are ideal for UASB reactors because they provide:
1. Superior Corrosion Resistance
UASB reactors handle wastewater with varying pH levels, organic acids, and sulfides. The glass-fused coating chemically bonds to the steel substrate, protecting it against corrosion and ensuring long-term tank integrity.
2. Structural Strength
The steel substrate of the GFS tank provides mechanical stability to withstand hydrostatic pressure, sludge weight, and operational loads, including maintenance access, piping attachments, and occasional seismic events.
3. Sanitary and Smooth Surfaces
The smooth glass coating prevents adhesion of solids and microbial fouling, which enhances sludge blanket stability and improves treatment efficiency.
4. Long Service Life
With an expected operational life of 30+ years, GFS tanks reduce maintenance costs, downtime, and replacement needs, providing a lower total cost of ownership.
5. Low Maintenance Requirements
Unlike concrete tanks or uncoated steel, GFS tanks do not require frequent chemical cleaning or surface repair, reducing operational labor and chemical use.
Technical Advantages of UASB Reactors
UASB reactors are designed to process wastewater efficiently while generating biogas as a valuable byproduct. Key technical advantages include:
• High Treatment Efficiency – Capable of removing up to 90% of Chemical Oxygen Demand (COD) from industrial and municipal wastewater.
• Biogas Production – Methane-rich gas can be captured for energy generation, offsetting operational costs and reducing carbon footprint.
• Compact Footprint – Vertical upflow design reduces land requirements compared to conventional aerobic systems.
• Robust Sludge Retention – The sludge blanket retains active microbial populations, ensuring consistent treatment performance.
• Adaptability – Suitable for a wide range of industries including food and beverage, pulp and paper, textile, chemical, and municipal wastewater systems.
By integrating UASB technology with Glass-Fused-to-Steel tanks, Center Enamel maximizes both the biological efficiency and structural longevity of wastewater treatment installations.
