Double Membrane Biogas Holder for Papermaking Wastewater Treatment:
Collects and Holds the Biogas from the Digestion of High-Solids,
Organic Mill Waste
Papermaking wastewater treatment facilities face the challenge of managing massive volumes of high-solids, organic mill waste (sludge, fiber fines, and process water). The anaerobic digestion
(AD) of this effluent is an effective method for stabilization and,
crucially, generates a significant volume of methane-rich biogas. For the mill to maximize energy recovery and ensure strict
environmental compliance, the biogas must be reliably and securely collected and held before being utilized for energy production to offset the mill’s
substantial energy demands. The storage solution must be
integrated, highly efficient at capture, and durable enough to
withstand the demanding, corrosive environment of the papermaking
industry.
The Double Membrane Biogas Holder is the optimal technology for this industrial application. It collects and holds the biogas from the digestion of high-solids,
organic mill waste. Installed either as an integrated flexible roof on the digester
or as a compact, free-standing unit, this holder provides a
dynamic, hermetic reservoir specifically designed for high gas
flows. 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, turning a waste
liability into a core energy asset for the paper mill.
Product Advantages for Industrial Biogas Recovery
Center Enamel’s Double Membrane Biogas Holders are meticulously
engineered to handle the substantial and demanding gas output
characteristic of papermaking effluent 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 fluctuations in biogas production inherent in large-scale industrial digestion.
This acts as a perfect buffer, stabilizing the low pressure and supply of gas to the mill’s utilization equipment (e.g., boilers or gas
turbines). 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-solids, organic mill
waste is typically high in moisture and can contain various
corrosive trace elements. 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
challenging industrial environment.
High-Volume and Flexible Capacity Management
The vast scale of papermaking operations results in high-volume,
continuous biogas production. The holder's design provides a flexible reservoir that can dynamically expand and contract to accommodate these substantial gas flows. This dynamic buffering is essential for ensuring a smooth,
stable, and regulated low-pressure supply of gas to high-capacity
utilization equipment, protecting the expensive machinery and
maximizing energy uptime.
