In the critical sequence of industrial and municipal water management, the first step is often the most important. Raw water, sourced from rivers, lakes, groundwater, or rainwater, contains a complex mix of minerals, organic matter, and particulates that must be carefully managed before any treatment process begins. A high-performance Raw water tank serves as the essential buffer, protecting downstream purification systems from surges in turbidity and ensuring a consistent supply for production.
Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), the premier China Raw water tank manufacturer, stands as a global leader in providing the engineering precision required for these primary storage assets. By integrating our proprietary Epoxy Coated Tanks with the structural resilience of Aluminum Dome Roofs, we deliver Water Tanks that resist the aggressive nature of untreated water while simplifying the transition to clean, usable resources. With a legacy spanning decades and installations in more than 100 countries, Center Enamel is the trusted partner for establishing a secure and efficient water foundation.
A Raw water tank is more than a simple holding vessel; it is a strategic asset that enhances the efficiency of the entire water treatment plant.
Natural water sources are rarely stable. Heavy rainfall can cause a sudden spike in river levels and sediment, while dry seasons can lead to scarcity. Water Tanks act as a hydraulic stabilizer, allowing treatment plants to operate at a constant, optimized flow rate regardless of external environmental fluctuations.
Storing water in a dedicated Raw water tank allows for natural sedimentation. Large particles and heavy silts can settle at the bottom before the water enters fine filtration or membrane systems. This "passive pre-treatment" significantly extends the life of expensive filters and reduces the chemical demand of the purification process.
For industrial facilities, a sudden loss of raw water intake can lead to an immediate shutdown of cooling towers, boilers, and production lines. Maintaining a robust reserve of raw water provides the critical time needed to address intake issues without halting the entire enterprise's operations.
As a specialized China Raw water tank manufacturer, Center Enamel utilizes Fusion Bonded Epoxy (FBE) technology to provide a molecularly fused shield for primary water storage. Our Epoxy Coated Tanks are specifically engineered to handle the unpredictable chemical and physical profile of untreated water.
The FBE process involves the electrostatic application of high-performance epoxy powder to preheated high-strength steel panels.
Unpenetrable Molecular Barrier: The epoxy melts and molecularly fuses with the steel, creating a dense, cross-linked polymer layer. This creates a hard, glass-like shield that is chemically inert, preventing the localized pitting and corrosion that often occur when raw water contains high levels of chlorides or sulfates.
Pinhole-Free Reliability: Every panel of our Water Tanks undergoes high-voltage spark testing (typically between 1100V and 1500V) to ensure coating integrity. This ensures that the Raw water tank remains leak-proof and maintenance-free throughout its extensive service life.
Exceptional Edge Protection: Our FBE technology provides superior coverage around panel edges and bolt holes—the most vulnerable points in traditional bolted tank designs. This comprehensive protection ensures structural integrity even in the presence of abrasive silts or varying pH levels.
To protect the integrity of the stored water and the structure itself, Center Enamel integrates Aluminum Dome Roofs into our Raw water tank designs.
Inherent Corrosion Resistance: Raw water headspaces can be highly humid and corrosive. Aluminum naturally forms a protective oxide layer that resists these conditions. Unlike steel roofs, our Aluminum Dome Roofs never require painting or sandblasting, resulting in a low lifetime maintenance cost.
Effective Algae and Contamination Control: Algae growth is triggered by sunlight. Our opaque geodesic domes block UV rays, naturally suppressing algae growth and keeping the raw water clear of biological blooms. Additionally, the dome prevents the ingress of debris, birds, and other external contaminants.
Clear-Span Structural Strength: The geodesic design provides massive strength without internal support columns. This is ideal for large-capacity Water Tanks, as it maximizes the storage volume and allows for the easy installation of internal monitoring systems or intake baffles.
Lightweight and Seismic Resistance: The low weight-to-strength ratio of aluminum domes places less stress on the tank walls and foundation, making them the preferred choice for facilities in seismically active regions.
Shijiazhuang Zhengzhong Technology Co., Ltd stands as the most professional bolted tank manufacturer in China. Our status as a premier China Raw water tank manufacturer is built on a commitment to international quality and engineering excellence.
Our Water Tanks are produced on automated production lines and comply with international standards such as ISO 28765, AWWA D103-09, and NSF/ANSI 61. This ensures that every Epoxy Coated Tank we deliver meets the highest global requirements for safety and performance.
Raw water infrastructure projects often operate on tight construction schedules. Our modular, bolted design allows for rapid assembly on-site using specialized jacking systems. This eliminates the need for on-site welding or coating and allows the Raw water tank to be commissioned much faster than traditional concrete or welded steel structures.
The performance of our technology is proven through successful deployments in diverse environments. We select the following non-fictitious cases to demonstrate our capability.
In the Ecuador Project, our tanks provided the foundational storage for a municipal water system. As a Raw water tank, these units effectively managed local water sources, providing the buffer needed to ensure a consistent flow of water to the treatment stages and eventually to the community.
The Hebei Agriculture Water Project involved the installation of 2 units of tanks. This project demonstrates our ability to deliver high-capacity Water Tanks that handle untreated regional water, providing the vital reserves necessary for large-scale crop irrigation and livestock support.
The Muyuan Group Suining Project utilized 2 units of tanks. Managing massive volumes of process water in an intensive industrial setting requires tanks that can withstand varying chemical profiles—the same durability required for a high-performance Raw water tank in a manufacturing or energy facility.
Modern industry is moving toward "Zero Liquid Discharge" (ZLD) and advanced water reclamation. Our Raw water tank systems are designed to support these sustainability goals:
Efficient Resource Management: By preventing evaporation and leakage, our tanks ensure that every drop of harvested water is available for the treatment process.
Reduced Chemical Burden: The passive sedimentation enabled by our tanks reduces the energy and chemical intensity of downstream filtration systems.
Asset Longevity: With a design life spanning decades and minimal maintenance requirements, our tanks represent a sustainable investment that minimizes the consumption of raw materials for repairs or replacements.
In the global market, the total cost of ownership (TCO) is the ultimate metric for infrastructure success. Center Enamel’s Water Tanks provide superior long-term value:
Minimal Maintenance Expenditures: The combination of Epoxy Coated Tanks and Aluminum Dome Roofs eliminates the need for the periodic sandblasting and repainting required by traditional materials.
Longevity in Aggressive Environments: Our materials are specifically engineered to resist the unique chemistry and biological activity of raw water, preventing the leaks and structural failures that lead to operational downtime.
Modular Scalability: The bolted design allows for the capacity of a Raw water tank installation to be expanded in the future as the facility's needs grow, protecting the initial capital investment.
As global water scarcity increases and industrial standards become more stringent, the quality of your raw water storage will define your operational success. A high-performance Raw water tank is the foundation of a modern, compliant, and efficient water management system.
