Stainless Steel Anaerobic Digester Tanks for Beverage Production Wastewater

Product Specification

Stainless Steel Anaerobic Digester Tanks for Beverage Production Wastewater Projects

In the beverage industry, wastewater contains high organic loads and nutrients that require effective treatment before discharge or reuse. One of the most efficient and sustainable technologies for managing this wastewater is anaerobic digestion (AD). For optimal performance in beverage production wastewater projects, stainless steel anaerobic digester tanks have become the material of choice due to their durability, corrosion resistance, and sanitary properties. As a global leader, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) supplies premium stainless steel anaerobic digester tanks designed specifically to meet the rigorous demands of beverage wastewater treatment.

As a leading storage tank manufacturer worldwide. Center Enamel can provide Glass Lined Steel(GLS) tanks, fusion bonded epoxy tanks, stainless steel tanks, galvanized steel tanks and aluminum geodesic dome roofs, Wastewater and Biogas Project Equipments for global customers.

Why Anaerobic Digestion in Beverage Wastewater?

Beverage production generates wastewater rich in sugars, organic acids, alcohols, and other biodegradable materials. Anaerobic digestion breaks down these organics in the absence of oxygen, converting them into biogas (methane and carbon dioxide) and a nutrient-rich digestate. This process offers several benefits:

• Significant reduction of organic pollutants and chemical oxygen demand (COD)
• Production of renewable energy (biogas) that can offset plant energy costs
• Lower sludge volume and disposal costs compared to aerobic treatment
• Reduced greenhouse gas emissions through renewable energy generation

Adopting anaerobic digestion aligns beverage production with sustainability goals and regulatory compliance for wastewater discharge.

Why Stainless Steel Tanks?

Exceptional Corrosion Resistance and Longevity

The anaerobic digestion environment is highly corrosive, involving acidic compounds, hydrogen sulfide (H2S), ammonia, and harsh biological activity. Stainless steel grades such as SUS304 and SUS316L excel in resisting corrosion caused by these aggressive substances. Unlike carbon steel or coated tanks, stainless steel remains structurally sound and operational for decades under such conditions, reducing the risk of leaks and costly repairs.

Hygienic and Non-Reactive Surface

Stainless steel features a non-porous, smooth surface that is easy to clean and resistant to bacterial colonization. This hygienic property is critical in the beverage industry where contamination can disrupt digestion performance and affect downstream uses of biogas and digestate. Stainless steel tanks maintain optimal biological conditions by minimizing unwanted microbial growth on tank surfaces.

Durable Under Temperature Fluctuations

Beverage wastewater and digestion processes involve temperature variations. Stainless steel can withstand thermal cycling without warping, cracking, or losing integrity, ensuring reliable operation of the digester under varying process temperatures.

Lightweight and Easy Installation

Compared to concrete or lined tanks, stainless steel tanks are comparatively lightweight, reducing foundation costs and easing installation. Shop-fabricated components and modular designs enable faster project completion.
