Center Enamel Empowers Oil & Gas Sustainability: Glass-Fused-to-Steel MBBR Tank for the Angola Oil and Gas Exploration Wastewater Treatment Project
As the oil and gas industry pushes into new exploration frontiers, the sustainable treatment of exploration wastewater has become central to responsible resource development. The Angola Oil and Gas Exploration Wastewater Treatment Project, completed in October 2025, sets a new standard for environmentally sound and robust industrial wastewater management. At the heart of this high-profile deployment is a custom-engineered Glass-Fused-to-Steel (GFS) Moving Bed Biofilm Reactor (MBBR) tank—designed, manufactured, and supplied by Shijiazhuang Zhengzhong Technology

``` Angola ranks among Africa’s most prominent oil-producing countries, with ongoing exploration efforts fueling economic growth and enabling the nation to attract significant foreign investment. Yet, the environmental challenges posed by exploration wastewater—laden with hydrocarbons, heavy metals, drilling additives, and varying levels of salinity—require advanced, reliable treatment strategies. Responsible operators recognize that effective, compliant treatment is not only a regulatory mandate but also a social and environmental imperative.
The Angola Oil and Gas Exploration Wastewater Treatment Project was conceived to provide a safe, scalable, and effective means of managing this complex waste stream. Center Enamel was chosen as the technology partner based on its global track record, technical innovation, and reputation for delivering high-integrity liquid storage and treatment solutions under the world’s toughest conditions.
Project Specifications: A High-Performance MBBR Tank Solution At the core of the project is a robust tank, purpose-built for use as the biological reactor in a cutting-edge MBBR process:
· Application: 油气勘探废水储罐 (MBBR 过程)

· Tank Size: 1 MBBR tank, φ6.11 meters diameter × 6.6 meters height
· Entrega: Construcción completada y proyecto comisionado en octubre de 2025, ahora completamente operativo
This configuration enables the treatment system to efficiently handle fluctuating volumes and shifting contaminant loads typical of oil and gas operations, providing vital operational flexibility and environmental protection.
Glass-Fused-to-Steel (GFS) 技术:卓越性能的基础 Glass-Fused-to-Steel tank technology is a hallmark of Center Enamel’s value proposition. By marrying the mechanical strength of steel with the chemical resistance and smoothness of glass, GFS panels offer a suite of inherent advantages that are critical in harsh industrial settings.
Production Process: Special, high-strength steel sheets are shaped and meticulously cleaned before being coated—inside and outside—with raw glass slurry. These panels are then fired in giant kilns at temperatures exceeding 820°C, causing the glass to vitrify and fuse to the steel at the molecular level. The resulting material is durable, non-porous, and entirely impervious to even the most aggressive water and chemical environments.
Core Advantages for Oil & Gas Wastewater Applications · Supreme Corrosion Resistance: GFS elimina problemas como óxido, picaduras y degradación, superando a los recubrimientos epóxicos estándar y a los aceros no protegidos, especialmente en entornos que contienen ácidos, sulfuros, hidrocarburos y sales disueltas.
· Chemical Inertness: La surface en verre est hautement non réactive, garantissant que ni les hydrocarbures ni les traces de métaux lourds ne provoquent de dégradation ou ne présentent un risque de lixiviation, assurant ainsi la qualité de l'eau.
· Fácil Mantenimiento: La superficie lisa y vidriosa minimiza la acumulación de lodo, incrustaciones y biopelículas, agilizando las operaciones de limpieza y apoyando un rendimiento constante del proceso.
· Estructural Fuerza: Los paneles están diseñados para soportar presiones internas y externas, cargas ambientales y tensiones cíclicas, garantizando la integridad mecánica necesaria para los sitios de exploración.
· Modular Flexibility: Bolted assembly enables rapid on-site construction, future scalability, and simple relocation if the operational footprint changes—ideal for dynamic exploration environments.
The Role of MBBR Technology in Exploration Wastewater Treatment The MBBR tank provided by Center Enamel functions as the biological “heart” of the Angola treatment plant. MBBR technology is recognized worldwide for its versatility and effectiveness in treating high-strength and variable wastes.
How It Works:
· 特别设计的生物膜载体介质悬浮在水箱的液相中。
· À medida que as águas residuais fluem, uma comunidade robusta de microrganismos cresce no meio, quebrando ativamente contaminantes orgânicos, hidrocarbonetos e nutrientes.
· Aeration maintains both mixing and oxygen supply, ensuring an aerobic environment for biological treatment.
· El sistema se adapta automáticamente a las fluctuaciones en la carga, sin necesidad de complicados sistemas de retorno de lodos y apoyando la resiliencia en instalaciones remotas o con limitaciones de mano de obra.
By combining the MBBR process with a vessel engineered for maximum durability and process compatibility, Center Enamel’s solution ensures superior pollutant reduction, minimal operational input, and reliable compliance with Angola’s evolving discharge standards.
Project Execution: Design, Engineering, and Delivery From project award through commissioning, Center Enamel delivered integrated support and technical leadership:
Project engineers worked closely with the client’s environmental, operations, and compliance teams to customize a tank configuration optimized for the site’s influent characteristics, treatment goals, and operational realities. Stress analysis, wind and seismic safety calculations, and future upgrade considerations were all integrated into the design, upholding international standards and best practices.
Fabrication and Quality Assurance Production took place at Center Enamel’s world-class manufacturing facility. Each GFS panel underwent rigorous visual, dimensional, and coating thickness inspections. The firing process was monitored to guarantee continuous glass coverage and bond strength. Quality checks followed ISO 9001 and relevant sector certifications to underpin reliability.
Shipping, Installation, and Commissioning The modular tank panels, hardware, and prefabricated roof structure were shipped to Angola, where Center Enamel’s installation experts managed site preparation, assembly, pressure testing, and final commissioning. The entire process—from site readiness to operational handover—was completed within schedule, despite challenging logistics.
Environmental and Economic Impact The successful commissioning of the Angola Oil and Gas Exploration Wastewater Treatment Project delivers results far beyond the boundaries of a single industrial facility.
Key Outcomes:
