In the global agricultural sector, effective wastewater management is paramount. Wastewater from livestock facilities like dairy farms and piggeries is a complex mixture of manure, urine, bedding, and feed remnants. If unmanaged, this stream can lead to severe environmental consequences, including groundwater pollution, soil degradation, and foul odors. Safe and reliable containment is the first step in comprehensive waste management, and Epoxy Coated Tanks provide the necessary durability, corrosion resistance, and structural integrity for this task.
Shijiazhuang Zhengzhong Technology Co., Ltd, known globally as Center Enamel, is a leading China Epoxy Coated Tank manufacturer. We leverage decades of experience and cutting-edge engineering to develop containment systems that meet the formidable demands of agricultural wastewater management.
Modern agricultural operations require integrated manure management systems that facilitate the entire treatment lifecycle. Center Enamel’s Fusion Bonded Epoxy (FBE) coating technology provides a high-performance barrier against corrosive organic byproducts.
Our tanks serve as primary infrastructure for slurry storage solutions, engineered to handle high static loads and varying chemical compositions of livestock effluent. The internal FBE coating ensures structural integrity is never compromised by the acidic environment typical of raw manure.
Our vessels are easily configured as anaerobic digestion tanks for farms focusing on renewable energy. The modular bolted design and high-performance sealants create the airtight environment necessary for efficient methane production, turning storage units into high-yield AD project components.
These tanks are utilized for wastewater equalization in industrial and municipal applications, balancing flow rates to protect downstream processes. Furthermore, 100% discontinuity-free coating, verified by 1100V holiday testing, makes them ideal for leachate containment, preventing hazardous runoff from contaminating groundwater.
This data confirms high-performance standards for durability, chemical resistance, and structural integrity.

● Corrosion Mastery: The ability to withstand 50% sulfuric acid and pH levels as low as 3.0 makes this coating ideal for acidic livestock wastewater and anaerobic digestion.
● Quality Assurance: The Holiday Test at 1100V ensures the coating is entirely free of pinholes, preventing steel exposure to corrosive elements.
● Mechanical Strength: Withstanding 160 in-lbs of impact with a 2H hardness rating ensures the tank can handle the rigors of industrial operations.
Choosing between Epoxy Coated Steel Tanks and traditional concrete impacts long-term ROI and environmental compliance.
Feature | Epoxy Coated (FBE) Steel Tanks | Concrete Tanks |
Corrosion Resistance | Superior: Inert FBE coating resists H2S and ammonia (pH 3–12). | Low: Susceptible to biogenic sulfuric acid corrosion and "pitting". |
Installation Speed | Fast: Prefabricated bolted panels allow rapid on-site assembly. | Slow: Requires extensive site prep, formwork, and curing times. |
Leak Prevention | High: Precision-engineered seals; factory-tested for zero discontinuities. | Moderate: Prone to structural cracking over time from ground settling. |
Lifespan | 30+ Years: Designed for long-term durability with minimal upkeep. | Variable: Often requires expensive liners or repairs after 10–15 years. |
Environmental Risk | Minimal: Sealed system prevents nitrate leaching into groundwater. | Higher: Cracks can lead to undetected seepage and regulatory fines. |
● Chemical Resilience: FBE coating provides a non-porous barrier unaffected by the acidic levels common in livestock waste that can degrade concrete.
● Modular Flexibility: Unlike poured concrete, a bolted steel tank is scalable, allowing for capacity increases as a farm grows.
● Quality Controlled Fabrication: Panels are factory-coated and tested, including 1100V Holiday Testing, ensuring a precision impossible with on-site concrete pours.
In 2023, Center Enamel commissioned several major livestock wastewater storage tank projects across China, totaling over 22,000 m³ of capacity.
Project Name | Location | Configuration | Total Volume |
Muyuan Group Suyu Project | Zhanjiang, Guangdong | 20.64 x 7.2m 29.81 x 7.2m | 7,429 m³ |
Nanning Pig Farming | Nanning, Guangxi | 29.81 x 7.2m 20.64 x 7.2m | 7,429 m³ |
Muyuan Group Jiangsu | Nantong, Jiangsu | 20.64 x 7.2m 29.81 x 7.2m | 7,158 m³ |
These projects highlight the critical role of FBE coating in modern systems. Large-diameter tanks handle massive static loads, while FBE provides a resilient defense against corrosive swine waste. Dual-tank configurations facilitate effective wastewater equalization, maximizing biogas yield in anaerobic digestion processes.
Q1: How does epoxy coating compare to concrete for livestock waste?
Answer: While concrete is traditional, it is porous and susceptible to biogenic sulfuric acid corrosion and structural cracks. FBE coating provides a non-porous, chemically inert barrier engineered to resist ammonia and $H_2S$. Modular tanks also offer faster, more cost-effective installation.
Q2: What is the lifespan of an FBE tank in highly acidic environments?
Answer: Center Enamel’s FBE tanks are designed for a service life of 30+ years. The coating is tested for a pH range of 3 to 12, and panels undergo 1100V Holiday Testing to confirm zero discontinuities.
Q3: Can these tanks be used for wastewater equalization in industrial settings?
Answer: Yes, their structural strength handles heavy static loads of large liquid volumes, while the FBE coating protects against diverse industrial wastewater.
Q4: Is the coating resistant to mechanical damage during cleaning?
