The art of winemaking, from crushing grapes to fermentation and bottling, is a globally cherished tradition. However, this seasonal, high-volume process generates a unique wastewater stream that presents a significant challenge to environmental compliance and operational stability. Winemaking Wastewater Treatment is characterized by high acidity (low pH), extremely high organic loads (BOD/COD) from sugars and tartrates, and substantial seasonal flow variations.
During harvest (the vintage), wastewater volumes spike, and the effluent's aggressive chemistry—rich in organic acids and often containing cleaning agents—is highly corrosive to conventional containment infrastructure. Traditional concrete tanks crack under thermal stress and acid attack, leading to leaks, contamination, and costly regulatory penalties. In a sector where quality and sustainability are paramount, reliable containment is non-negotiable.
Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), a distinguished China Epoxy Coated Steel Tank manufacturer, delivers the definitive, engineered solution: the Fusion Bonded Epoxy (FBE) Bolted Steel Tank. As the premier Epoxy Coated Steel Tank technology, it is uniquely designed to provide absolute chemical resistance and structural integrity, forming the durable foundation for modern Winemaking Wastewater Treatment and resource recovery.
Winery wastewater is highly corrosive and variable, requiring a storage solution that can reliably handle chemical volatility and extreme seasonal usage.
Wastewater originates primarily from washing, barrel cleaning, and equipment sterilization. The most challenging component is the high concentration of organic acids (tartaric, malic, lactic, and acetic) and sugars, particularly during the crush. This results in a naturally low pH environment, often below 4.0, which aggressively attacks cement and compromises standard coatings. In holding and equalization tanks, the rapid fermentation of residual sugars further exacerbates this acidity, accelerating corrosion.
Unlike steady industrial flows, winery wastewater generation is intensely seasonal. The majority of the annual volume is discharged during the 6-10 week harvest period. This necessitates large-capacity equalization tanks that can handle massive, sudden inflows. The containment structure must maintain structural integrity when full, when near-empty, and withstand periods of dormancy, without being compromised by settlement or stress.
Wineries utilize strong cleaning agents, including caustic solutions and various sanitizers, to maintain the hygiene required for quality wine production. These chemicals, when discharged, cause rapid and dramatic pH swings in the effluent, from highly acidic (organic acids) to highly alkaline (cleaning agents). The Epoxy Coated Steel Tank coating must maintain absolute integrity through this chemical and thermal onslaught.
The wastewater contains significant volumes of grape skins, seeds, lees (spent yeast), and general suspended solids. These materials settle in tanks, creating dense sludge layers. The tanks must be structurally robust to handle the static load of this dense sludge and the dynamic load of mechanical scrapers or mixers used to maintain process efficiency.
Center Enamel’s FBE Bolted Steel Tank is the product of advanced engineering, providing an uncompromising solution perfectly suited for the volatile environment of Winemaking Wastewater Treatment.
The FBE coating is a chemically fused, non-leaching barrier that provides total defense against wine waste chemistry:
Molecular Bonding: The epoxy powder is electrostatically applied and thermally fused to the meticulously prepared steel surface. This high-heat curing process creates an irreversible, molecular bond—not just a surface layer—resulting in a dense, uniform, and pinhole-free coating.
Acid and Alkaline Immunity: This factory-applied coating is chemically inert to the aggressive organic acids (pH<4) and the strong caustic cleaning solutions (pH>11) found in winery effluent, ensuring the steel substrate is never exposed to corrosion.
Smooth, Hygienic Surface: The FBE finish is smooth and non-porous, minimizing the adhesion of solids, yeast, and biofilms (biofouling), which simplifies tank cleaning and reduces maintenance costs inherent in Winemaking Wastewater Treatment.
As a premier China Epoxy Coated Steel Tank manufacturer, Center Enamel focuses on delivering structural security and logistical efficiency tailored for seasonal operations:
High-Strength Construction: Built from high-grade carbon steel, the tanks are engineered to safely contain dense sludge and withstand the dynamic loads from agitators and mixing equipment, crucial for optimizing biological treatment processes.
Modularity for Rapid Deployment: The modular, bolted design utilizes prefabricated components, eliminating the long construction times and wet curing periods associated with concrete. This is vital for wineries needing to quickly expand capacity before the next vintage, minimizing operational downtime.
Scalability and Flexibility: The FBE bolted system is inherently scalable. As a winery's production grows, new tanks can be seamlessly integrated, or existing tanks can be expanded, offering a flexible solution that protects the initial capital investment over multiple growth cycles.
Consistent Quality: Every FBE panel is manufactured under strict ISO-certified quality control in our advanced facility, ensuring every Epoxy Coated Steel Tank meets the identical, robust specification for reliable use globally.
Center Enamel has a robust track record supporting the high-strength beverage and alcohol production industries, proving the FBE Epoxy Coated Steel Tank is the reliable choice for challenging organic wastewater streams. These three unrepeated cases highlight its capability to handle the massive volumes and corrosive nature of alcohol-related effluent.

We supplied 2 units of tanks with a total capacity of 42,188 cubic meters. This case powerfully demonstrates the FBE tank's capability to handle extraordinary volumes and the aggressive nature of major alcohol industry discharges.
Sichuan Brewing Wastewater Treatment Project: Located in a region known for high-volume beverage production, this installation required multiple, chemically resilient vessels for the biological and physical treatment of brewing effluent. We supplied 6 units of tanks with a total capacity of 14,648 cubic meters. This project underscores the FBE tank's proven structural stability and chemical durability in managing the high-load, variable flow conditions typical of the beverage sector, including wineries.

We supplied 1 unit of a tank with a total capacity of 2,515 cubic meters. This installation confirms the FBE tank's resistance to the highly corrosive organic acid profiles generated during high-alcohol fermentation and distillation processes, making it perfectly suited for similar challenges in Winemaking Wastewater Treatment.
Choosing the FBE Epoxy Coated Steel Tank is a strategic decision that drives sustainability, lowers risk, and optimizes the financial performance of Winemaking Wastewater Treatment facilities.
Winery wastewater is an excellent feedstock for anaerobic digestion. By serving as the secure, chemically resistant vessel for digesters, the FBE tank enables wineries to convert high-BOD effluent into biogas (renewable methane). This recovered energy can significantly offset the winery's high seasonal energy consumption, turning a waste stream into a valuable source of power and lowering operational expenses.
The absolute, leak-proof integrity of the FBE Epoxy Coated Steel Tank guarantees that highly acidic or chemically treated wastewater is securely contained. This ensures wineries meet stringent environmental discharge regulations, protecting local water resources and vineyards from contamination, and mitigating the risk of expensive fines and litigation.
Designed for a service life of 30 years or more with minimal internal maintenance, the FBE tank eliminates the cyclical costs associated with concrete failure, crack repair, and frequent relining common with other systems. By maximizing lifespan and minimizing upkeep, the FBE solution provides the lowest TCO over the operational life of the Winemaking Wastewater Treatment facility.
The structural and chemical resilience of the FBE coating guarantees that the containment infrastructure remains fully functional during the critical vintage period, regardless of the high flow rates, extreme pH changes, and thermal fluctuations, ensuring continuous production and treatment.
