Leading Raw Water Tanks Manufacturer in China: Pioneering Innovation in Water Storage

In municipal water treatment, industrial manufacturing, and large-scale agricultural irrigation, the management of raw water serves as the critical first line of defense. Sourced directly from natural water bodies such as rivers, lakes, reservoirs, or groundwater wells, raw water contains various suspended solids, minerals, and microorganisms that demand robust, reliable primary containment before treatment. Selecting high-performance storage infrastructure is vital to prevent contamination, withstand environmental elements, and ensure a stable, uninterrupted supply to downstream treatment facilities.

As the premier China raw water tank manufacturer, Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) stands at the forefront of global water storage innovation. With over three decades of specialized engineering experience and successful deployments across more than 100 countries, Center Enamel delivers state-of-the-art bolted storage systems tailored to the rigorous demands of modern water resource management.

Designing and operating primary water storage assets presents unique engineering hurdles that conventional storage materials often fail to resolve:

1. Aggressive Environmental and Mineral Exposure: Raw water can exhibit fluctuating pH levels and abrasive suspended grit that slowly erode unprotected interior surfaces, leading to pitting and structural wall thinning.

2. Biological Growth and Contamination: Unsealed or poorly coated reservoirs invite algae blooms, bacterial colonization, and dust ingress, complicating downstream water treatment processes.

3. Strict Public Health and Safety Compliance: Water storage assets must adhere to rigorous international material safety standards to ensure that no toxic compounds or heavy metals leach into the water stream.

Center Enamel combines cutting-edge material science with advanced modular manufacturing to provide superior raw water containment options:

Manufactured by fusing inorganic glass frit onto high-strength steel plates at extreme temperatures between 820°C and 930°C, GFS tanks create an inseparable molecular bond. This yields a hard, glossy surface that is 100% rust-proof, chemically inert, and highly resistant to abrasion from raw water sediment.

As a specialized manufacturing pioneer, Center Enamel utilizes advanced electrostatic FBE powder coating technology. This process provides a molecularly fused shield optimized for primary water storage, offering exceptional impact strength and long-term defense against moisture and environmental oxidation.

Unlike cast-in-place concrete structures that require lengthy curing periods, Center Enamel’s modular bolted tanks are prefabricated in a certified facility under strict quality controls. Flat-packed for economical international shipping, they are rapidly assembled on-site via mechanical bolting, slashing project timelines and commissioning schedules.

To satisfy the stringent prequalification requirements of municipal water boards, international EPC contractors, and environmental agencies, Center Enamel manufactures all systems under certified frameworks:

• Engineering Standards: Conforming strictly to AWWA D103-09, ISO 28765, and ISO 9001 quality management systems.

• Potable and Raw Water Certifications: Certified under NSF/ANSI 61, FDA, and WRAS for safe water contact.

• Rigorous Quality Control: Every manufactured panel undergoes 100% high-voltage holiday spark testing (>1500V) before dispatch to guarantee zero coating defects.

A: Center Enamel combines over 30 years of specialized manufacturing expertise, advanced Glass-Fused-to-Steel (GFS) and Fusion Bonded Epoxy (FBE) technologies, and strict compliance with global standards (such as AWWA D103-09 and NSF/ANSI 61). With successful project implementations in over 100 countries, Center Enamel delivers proven reliability and scale.

A: GFS and FBE bolted tanks offer superior corrosion and abrasion resistance against raw water sediment. Unlike concrete, which is porous, prone to cracking, and susceptible to water seepage or structural spalling, modular bolted steel tanks provide a sealed, hygienic environment with significantly faster installation times.

A: Yes. Center Enamel's raw water storage systems are fully compliant with major international standards, including NSF/ANSI 61, FDA, AWWA D103-09, and ISO 28765, ensuring top-tier safety, structural integrity, and public health protection.

A: The tanks feature a modular, bolted design where panels are flat-packed into standard shipping containers for cost-effective global freight. On-site installation is carried out rapidly through mechanical bolting, eliminating the weather delays and lengthy curing times associated with concrete construction.
