China’s Leading Industrial Park Wastewater Storage Tank Manufacturer — Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel)
Industrial parks are the beating heart of modern economies, hosting thousands of manufacturers, processing facilities, and logistics operations. However, behind their economic success lies a growing environmental challenge: industrial wastewater management. Each industrial zone generates significant volumes of contaminated water containing chemicals, heavy metals, oils, and organic pollutants. If these discharges are not properly contained and treated, they can threaten soil, groundwater, and surrounding ecosystems.
To address this vital issue, municipalities and industrial developers are investing heavily in wastewater storage systems—a cornerstone of modern environmental management. These systems provide safe, temporary containment of untreated or partially treated wastewater before it is conveyed for recycle or final treatment.
At the forefront of this crucial infrastructure sector is Shijiazhuang Zhengzhong Technology Co., Ltd., known worldwide as Center Enamel. Recognized as China’s leading manufacturer of industrial park wastewater storage tanks, Center Enamel is powering sustainable industrial growth across more than 100 countries through advanced Glass-Fused-to-Steel (GFS) tank technology, engineering excellence, and a steadfast commitment to environmental protection.
Industrial parks accommodate diverse operations—chemical manufacturing, food processing, textiles, pharmaceuticals, paper mills, and electronics production—all of which generate varying volumes and types of wastewater. Contaminated with toxic organics, corrosive compounds, and solids, this wastewater cannot be discharged directly into municipal networks.
Modern environmental management relies on on-site wastewater storage tanks to collect, equalize, and buffer effluents, ensuring optimal flow rates and consistent water quality for downstream treatment processes.
Key purposes of wastewater storage tanks in industrial parks include:
· Flow equalization to stabilize hydraulic loads entering treatment systems.
· Segregation of contaminated streams from clean or partially treated wastewater.
· Emergency containment of accidental spills or process upsets.
· Buffer storage before recycling or final discharge in compliance with standards.
· Resource recovery integration, such as reuse for cooling or fertilization after treatment.
Reliable, corrosion-resistant storage systems are therefore essential to maintaining regulatory compliance, safeguarding the environment, and protecting public health within every industrial estate.
Founded in 2008, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) is China’s first manufacturer of Glass-Fused-to-Steel (GFS) tanks and remains the country’s most advanced and experienced specialist in bolted steel storage solutions.
For over 35 years, Center Enamel has supplied tanks for water, wastewater, biogas, sludge, and industrial processes to clients across the world, combining environmental responsibility with best-in-class engineering.
Company achievements at a glance:
· 150,000 m² state-of-the-art production facility in Shijiazhuang, Hebei Province.
· Production of over 300,000 enamel-coated steel panels annually.
· Export experience to over 100 countries and regions.
· More than 30,000 completed projects worldwide.
· Compliance with prominent international standards, including AWWA D103, EN ISO 28765, NSF/ANSI 61, EN 1090, and ISO 9001/14001/45001.

With a workforce of seasoned engineers, scientists, and project managers, Center Enamel continues to lead the global tank industry by delivering innovative, durable, and sustainable containment systems.
The key to Center Enamel’s success lies in its proprietary Glass-Fused-to-Steel (GFS) technology—an advanced coating technique that fuses molten glass to steel at temperatures between 820°C–930°C, creating an inert and ultra-durable composite material.
The GFS bonded layer combines the flexibility and strength of steel with the corrosion resistance and impermeability of glass, forming a surface that performs exceptionally well under aggressive wastewater conditions.
Benefits of GFS coatings:
· Resistance to acids, alkalis, salts, chemical oxidizers, and biological agents.
· Complete gas and liquid impermeability.
· Easy cleaning due to smooth, non-stick surfaces.
· Long service life exceeding 30 years with minimal maintenance.
· Non-toxic, food- and water-safe surface; fully compliant with health standards.
This makes the technology ideal for industrial wastewater storage, where tanks must endure harsh chemical exposure and fluctuating pH levels over long operational cycles.
Unlike municipal wastewater, industrial effluent exhibits high variability in both quality and toxicity. Each industry produces distinctive contaminants requiring specialized containment systems.
Common challenges include:
· Highly corrosive fluids from chemical and metal-processing industries.
· Abrasive solids and high-temperature discharges.
· pH extremes (from <3 to >12) damaging conventional coatings.
· Toxic gases like H₂S and NH₃ leading to corrosion and odor.
· Regulatory demands for zero leakage and safe long-term operation.
Center Enamel’s GFS tanks meet all these challenges with proven chemical resistance, robust structure, and precise engineering design, making them a superior alternative to concrete tanks (which crack and leak) or epoxy-coated steel tanks (which degrade quickly under aggressive pH and oxidation).
1. Superior Corrosion Resistance
The GFS coating ensures unbreakable bonding and corrosion-proof protection across a wide pH range (1–14), perfectly suited to industrial wastewater environments.
2. Airtight and Leakproof Sealing
Bolted panels are connected with high-grade stainless steel fasteners and sealed using EPDM or PTFE gaskets, guaranteeing complete environmental isolation and odor control.
3. Rapid Modular Installation
Prefabricated panels are shipped flat-packed and assembled on-site with minimal equipment, reducing project duration by up to 50% compared to concrete alternatives.
4. Long-Term Service Life
A design life exceeding 30 years, verified through accelerated aging tests, results in significant savings in maintenance and replacement costs.
5. Excellent Mechanical Strength
High-tensile steel structure resists static and dynamic loads—earthquakes, wind pressure, hydrostatic weight, and heat expansion.
6. Eco-Friendly and Recyclable
Both steel and glass materials are fully recyclable and meet all requirements of green building and ESG certifications.
7. Aesthetic and Customizable
Available in multiple finishes and colors, tanks integrate seamlessly with modern industrial landscapes and branding requirements.
