Fusion Bonded Epoxy Tank for Dairy Wastewater Treatment: Ensures reliable storage for milk and processing effluents

Fusion Bonded Epoxy Tank for Dairy Wastewater Treatment: Ensures reliable storage for milk and processing effluents

Dairy wastewater treatment is essential for milk processing facilities, generating a waste stream characterized by high concentrations of milk solids, fats, proteins, and sugars. This effluent, combining spilled milk and processing effluents from cleaning and production, results in an extremely high biochemical oxygen demand (BOD) and significant fat, oil, and grease (FOG) content. The rapid decomposition of these components creates a challenge, demanding reliable storage that is structurally sound, resistant to organic acids, and hygienic. The Fusion Bonded Epoxy (FBE) Tank provides this necessary combination of durability and non-porous integrity. At Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), we utilize FBE bolted steel technology to deliver structurally superior and chemically resilient vessels that guarantee reliable storage and efficient pre-treatment for dairy wastewater.

The Corrosive and Hygienic Challenges of Dairy Effluent

Containing and treating milk and processing effluents requires a specialized solution due to the following challenges:

High Organic Load and FOG: Dairy effluent contains high concentrations of residual fat, oil, and grease (FOG), along with lactose and proteins. This FOG content can rapidly degrade porous liners and interfere with biological treatment processes. Tanks must be reliable and resistant to FOG penetration and adhesion.

pH Volatility and Acidic Attack: While fresh milk is near neutral, residual milk, whey, and cleaning-in-place (CIP) chemicals (both acidic and caustic) cause rapid and significant pH fluctuations. Furthermore, the rapid anaerobic decomposition of lactose produces lactic acid, creating a persistent, corrosive low-pH environment.

Risk of Biofouling: The rich nutrient content of dairy wastewater promotes rapid microbial growth and biofilm formation on tank walls. This fouling can reduce effective volume and complicate cleaning and disinfection protocols.

Temperature Fluctuation: Effluent from pasteurization and hot CIP cycles is often discharged at elevated temperatures. The tank and its coating must maintain their integrity and bond under continuous thermal stress.

Need for Continuous Flow: Dairy operations are continuous. Any failure in storage or equalization tanks can halt production or lead to environmental non-compliance, emphasizing the need for reliable, high-integrity containment.

Reliable storage is paramount to stabilize this volatile, high-load effluent before it enters sensitive biological treatment.

The FBE Solution: Reliable Storage for Milk and Processing Effluents

Center Enamel’s Fusion Bonded Epoxy Bolted Steel Tanks are engineered for dairy wastewater treatment, ensuring reliable storage for milk and processing effluents through key material and structural advantages:

Resistance to Organic Acids and FOG: The FBE coating is a dense, chemically inert polymer that is molecularly bonded to the steel. This non-porous barrier provides superior, long-term defense against the corrosive attack from organic acids and resists the penetration and adhesion of FOG, a common failure point for conventional liners.

Hygienic and Anti-Fouling Surface: The smooth FBE finish minimizes the adherence of sticky organic matter, proteins, and microbial biofilm. This feature is critical in the food industry for maintaining hygienic conditions and simplifying the necessary cleaning and sanitation procedures.

Structural Integrity for Equalization: Built from high-tensile, factory-engineered steel, FBE tanks offer the superior structural strength required to manage the immense hydraulic load of large-volume equalization basins, which are essential for stabilizing the highly variable flow of dairy wastewater.

Ideal for Pre-Treatment (DAF): FBE tanks are perfectly suited for Dissolved Air Flotation (DAF) process vessels, resisting the chemical effects of coagulants and flocculants while providing the robust structure required for solids separation.

Rapid Deployment and Versatility: The modular, bolted design allows for fast, predictable construction, enabling dairy facilities to quickly implement or expand crucial pre-treatment capacity with minimal disruption to continuous processing.

Product Industry Application: FBE Tanks in Dairy Wastewater Management

The resilience and purity of FBE tanks make them essential throughout the dairy wastewater treatment process:

Equalization Basins: The primary application, stabilizing the highly variable flow and pH of milk and processing effluents before subsequent treatment stages.

DAF Units and Clarifiers: Used for physical-chemical separation, where the FBE lining resists the combined corrosive effects of the effluent and chemical additives used in the DAF process.

Anaerobic/Aerobic Treatment: FBE tanks serve as the main reactor vessels for biological treatment, ensuring the environment is inert and structurally sound for high-load, high-rate digestion.

Whey and Sludge Holding: Used for the reliable storage of concentrated, dense sludge (rich in fats and proteins) and byproduct streams like whey, which are highly corrosive due to their lactic acid content.

Process Water and Firefighting Water: FBE tanks are also utilized elsewhere in the plant for clean process water and secured firefighting water storage, offering a standardized, reliable containment solution across the entire facility.
