Double Membrane Biogas Holder for a Pulp Mill Plant: Collects Biogas Resulting from High-BOD Paper Waste Effluent Treatment

Double Membrane Biogas Holder for a Pulp Mill Plant: Collects Biogas Resulting from High-BOD Paper Waste Effluent Treatment

scharacterized by a high organic load, measured as Biochemical Oxygen Demand (High-BOD paper waste effluent). The anaerobic digestion (AD) of this effluent is crucial for both reducing the environmental impact and recovering resources. This process generates a significant volume of methane-rich biogas. For the mill to maximize energy recovery, the biogas must be reliably and securely collected and buffered against fluctuations. This requires a robust, flexible, and durable solution designed specifically to handle the large gas flows resulting from high-BOD paper waste effluent treatment.

The Double Membrane Biogas Holder is the optimal technology for this demanding industrial application. It collects biogas resulting from high-BOD paper waste effluent treatment. Installed either as an integrated flexible roof on the digester 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 downstream utilization (e.g., boilers or CHP units), turning a waste liability into a core energy asset for the pulp mill.

Product Advantages for Pulp Mill Gas Management

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to handle the substantial gas output and challenging environment characteristic of paper waste treatment, maximizing the efficiency and safety of these high-load industrial plants.

Integrated Gas Collection 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 acts as a perfect buffer, stabilizing the low pressure and supply of gas to the mill’s utilization equipment. This stability is critical for continuous industrial operation, maximizing the use of renewable energy generated from the waste.

Resilience to Corrosive Industrial Gas

Biogas generated from the digestion of high-BOD paper waste 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 installed on or adjacent to a tank protected by an Aluminum Dome Roof . While the membrane system provides the essential flexible gas-tight envelope, the aluminum dome offers superior, lightweight long-term corrosion protection and structural support for the entire digester tank structure, enhancing overall system durability.
