Double Membrane Biogas Holder for a Distillery Wastewater Treatment Plant: Provides Superior Resistance for Harsh, High-Temperature Spent Wash Biogas

Double Membrane Biogas Holder for a Distillery Wastewater Treatment Plant: Provides Superior Resistance for Harsh, High-Temperature Spent Wash Biogas

A Distillery Wastewater Treatment Plant handles spent wash (or stillage), the liquid residue from alcohol production, which is characterized by extremely high organic strength, high acidity, and high temperatures. This residue poses a significant environmental challenge. Anaerobic digestion (AD) is the primary method used to treat this harsh effluent, generating a substantial volume of methane-rich biogas. For the distillery to maintain environmental compliance and achieve energy recovery, the biogas storage must offer superior resistance to corrosive elements and temperature variations. This solution must provide superior resistance for harsh, high-temperature spent wash biogas.

The Double Membrane Biogas Holder is the optimal technology for this extremely demanding industrial application. It efficiently provides superior resistance for harsh, high-temperature spent wash biogas. Installed either as an integrated flexible roof on the anaerobic reactor or as a compact, free-standing unit , this holder provides a dynamic, hermetic reservoir. This system ensures every cubic meter of gas is captured, pressure fluctuations are safely managed, and a stable, continuous supply is maintained for energy recovery, ensuring long-term plant viability under severe operating conditions.

Product Advantages for Harsh Spent Wash Biogas Management

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to handle the substantial gas output and the aggressive, corrosive, and thermal environment characteristic of spent wash digestion.

Advanced Resistance to Heat and Corrosion

The effluent from distilleries is often processed at elevated temperatures, leading to hot, humid, and corrosive biogas. The balloon is constructed from specialized, multi-layered composite fabric, which is selected for its exceptional durability and, critically, superior resistance to high temperatures, organic acids, and corrosive elements typical of spent wash digestion. This advanced resistance is crucial for the long-term integrity of the gas-tight seal, ensuring reliable operation and minimizing maintenance costs in this severe environment.

Reliable Gas Buffer for Continuous Energy Offset

Distillery operations are continuous and require significant energy, often offset by the recovered biogas. The balloon's design provides a flexible and dynamic gas reserve capacity that can dynamically expand and contract to accommodate the substantial volume fluctuations in biogas production. This dynamic buffering is essential for regulating the low pressure of the gas, preventing system instability, and ensuring a smooth, constant flow to utilization equipment. This stability is critical for maximizing the plant's internal energy offset.

Support for Aluminum Dome Roofs

Where maximum corrosion resistance and structural integrity are essential for the digester tanks—a paramount need when dealing with harsh, high-temperature industrial effluents—the Double Membrane Holder can be integrated with a tank protected by an Aluminum Dome Roof. While the membrane system provides the essential flexible gas-tight envelope, the aluminum dome offers superior long-term corrosion protection and robust structural support for the entire digester tank structure, extending the service life of the entire system.
