Double Membrane Biogas Holder for a Pulp Mill Wastewater Treatment Plant: Collects Biogas Resulting from the Treatment of Papermaking Effluents

A Pulp Mill Wastewater Treatment Plant manages the enormous volume of process water containing high levels of organic compounds, often referred to as papermaking effluents. The efficient and environmentally responsible method for stabilizing this high organic load is anaerobic digestion (AD), which, critically, generates a significant volume of methane-rich biogas. For the mill to maximize resource recovery and maintain continuous operation, the biogas must be reliably and securely collected and buffered. This requires a robust, flexible solution that collects biogas resulting from the treatment of papermaking effluents.

The Double Membrane Biogas Holder is the optimal technology for this demanding industrial application. It efficiently collects biogas resulting from the treatment of papermaking effluents. Installed either as an integrated flexible roof on the anaerobic reactor or as a large, 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 downstream utilization (e.g., steam generation), turning a necessary waste treatment step into a significant source of renewable energy for the mill.

Product Advantages for Papermaking Effluent Biogas Management

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to handle the substantial gas output and challenging environment characteristic of papermaking effluent treatment, maximizing efficiency and safety.

Integrated Gas Capture and Supply Stability

The system acts as the integrated flexible roof of the digester tank, ensuring maximum gas capture efficiency by collecting the gas instantly. The inner membrane's volume dynamically expands and contracts to accommodate the natural volume fluctuations in biogas production inherent in large-scale pulp mill digestion. This dynamic buffering is essential for regulating the low pressure of the gas, preventing system instability, and ensuring a smooth, constant flow to the mill’s utilization equipment. This stability is critical for maximizing the use of renewable energy generated from the waste.

Resilience to Corrosive Industrial Gas

Biogas generated from the digestion of papermaking effluents is often high in moisture and can contain various corrosive trace elements, making durability paramount. The balloon is constructed from specialized, multi-layered composite fabric, which is selected for its exceptional durability and resistance to corrosive elements. This resistance is crucial for the long-term integrity of the gas-tight seal, ensuring reliable operation, minimizing fugitive methane emissions, and reducing maintenance costs in this industrial setting.

Support for Aluminum Dome Roofs

Where maximum corrosion resistance and structural integrity are essential—a frequent requirement in the corrosive atmosphere of pulp and paper mills—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 structural support for the entire digester tank structure, enhancing overall system durability.
