Fusion Bonded Epoxy Tank for Livestock Wastewater Treatment: Built to resist the aggressive chemicals in animal waste

Fusion Bonded Epoxy Tank for Livestock Wastewater Treatment: Built to resist the aggressive chemicals in animal waste

Livestock wastewater treatment is one of the most chemically challenging applications in the agricultural sector. Animal manure, slurry, and washdown water contain high concentrations of organic acids, salts, and ammonia. The biological decomposition of these components creates a highly volatile, corrosive environment. Therefore, containment infrastructure must be specifically built to resist the aggressive chemicals in animal waste to ensure structural longevity and regulatory compliance. The Fusion Bonded Epoxy (FBE) Tank is engineered with a high-performance, chemically inert lining to withstand this continuous chemical attack. At Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), we utilize FBE bolted steel tanks to provide durable, secure, and resilient containment vessels, forming the essential foundation for effective and sustainable livestock wastewater treatment.

The Corrosive Attack of Animal Waste

The unique composition of animal waste requires a specialized containment solution due to several severe corrosive agents:

Ammonia and Nitrogen Compounds: High concentrations of nitrogen in manure decompose rapidly, leading to the release of ammonia. When ammonia gas contacts moisture in the tank headspace, it forms corrosive compounds that actively attack unprotected steel and concrete surfaces.

Organic Acid Formation: During the decomposition and fermentation of manure and slurry, volatile fatty acids (VFAs) are produced. These organic acids, along with lactic and acetic acids, create a pervasive low-pH environment that continuously erodes conventional tank linings.

Hydrogen Sulfide (H2​S) in Biogas: For facilities utilizing anaerobic digestion, the resulting biogas contains H2​S. This highly aggressive gas forms sulfuric acid on the tank walls and roof, leading to rapid, destructive corrosion if the lining is not highly specialized and chemically resistant.

High Solids and Density: Livestock wastewater is often a dense slurry, subjecting the tank base and walls to immense hydrostatic loads. The structure must be strong enough to handle this weight and the dynamic forces from continuous mixing equipment.

Abrasive Wear: The presence of bedding materials, grit, and sand in the slurry causes mechanical abrasion, which, when combined with chemical attack, quickly compromises standard steel or concrete integrity.

Containment must be built to resist this combination of chemical, biological, and physical aggression to guarantee a long service life.

The FBE Solution: Built to Resist Aggressive Chemicals

Center Enamel’s Fusion Bonded Epoxy Bolted Steel Tanks are engineered to ensure long-term viability in livestock wastewater treatment, specifically by being built to resist the aggressive chemicals in animal waste:

Chemical Inertness and Acid Resistance: The FBE coating is a dense, high-performance, thermoset polymer that is molecularly bonded to the steel. This inert barrier provides superior, long-term resistance to the full spectrum of corrosive agents found in animal waste, including ammonia, organic acids, and sulfuric acid (H2​S byproducts).

Structural Strength for Slurry Loads: Constructed from high-tensile, factory-engineered steel, FBE tanks offer superior structural integrity necessary to safely contain the immense weight of dense manure and slurry, ensuring stability and durability during mixing and pump-out operations.

Gas-Tight Sealing for Biogas/Odor Control: The precision-machined, bolted design and high-performance sealants ensure a gas-tight vessel, which is critical for two functions: safely containing valuable methane (CH4​) for energy recovery and minimizing the release of corrosive and odor-causing gases (like H2​S and ammonia).

Anti-Fouling and Low Maintenance: The smooth, non-porous FBE finish minimizes the adherence of sticky organic matter and solids, simplifying cleaning, reducing the buildup of corrosive sludge, and ultimately lowering long-term maintenance costs.

Rapid, Modular Deployment: The bolted design allows for extremely fast and predictable construction on-site, enabling farms to quickly expand their livestock wastewater treatment capacity to meet increasing stock numbers and tightening environmental regulations.

Product Industry Application: FBE Tanks in Livestock Wastewater Treatment

The resilience and chemical resistance of FBE tanks make them the definitive containment choice across livestock wastewater treatment facilities (dairy, swine, and poultry):

Manure Slurry Holding: FBE tanks are the primary vessels for secure, high-capacity storage of raw manure and slurry, providing resistance against the constant corrosive environment.

Anaerobic Digesters (AD): FBE tanks serve as the main reactor vessels for converting animal waste into valuable biogas and digestate, resisting H2​S and organic acid corrosion while maintaining gas-tight integrity.

Solid-Liquid Separation: Used for initial separation processes (e.g., flocculation, clarification), where the FBE lining resists both the corrosive agents and the abrasive nature of the suspended solids.

Effluent Equalization: Employed to stabilize the highly variable flow, temperature, and composition of washdown water and diluted manure before it enters the more sensitive biological treatment stages.

Post-Digestate Storage: The tanks securely hold the treated, nutrient-rich liquid digestate for controlled field application, ensuring environmental compliance until the optimal time for use.
