Double Membrane Biogas Holder for a Physical Wastewater Treatment Plant: Used to Manage Biogas Generated from Associated Anaerobic Sludge Processes

Double Membrane Biogas Holder for a Physical Wastewater Treatment Plant: Used to Manage Biogas Generated from Associated Anaerobic Sludge Processes

A Physical Wastewater Treatment Plant primarily employs physical separation techniques (like screening, sedimentation, and filtration) to remove solids and other particulates. Although the core process is physical, these plants invariably generate a significant volume of sludge. If this sludge is stabilized using anaerobic digestion (AD)—the most common method—a valuable energy co-product, methane-rich biogas, is created. The Double Membrane Biogas Holder is a critical component in this integrated system. It is used to manage biogas generated from associated anaerobic sludge processes, ensuring the recovered energy is captured and utilized efficiently to offset the plant's operational costs.

The Double Membrane Biogas Holder is the optimal technology for this application. It provides flexible, low-pressure containment for the recovered gas . Installed either as an integrated flexible roof on the sludge 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 energy utilization, turning a necessary waste management cost (sludge handling) into a source of renewable energy.

Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), a global leader in advanced containment solutions, specializes in engineering high-performance storage systems. Our Double Membrane Biogas Holders are state-of-the-art gas holders designed to integrate seamlessly within the infrastructure of a wastewater treatment plant, offering superior containment, pressure regulation, and long-term durability.

Product Advantages for Sludge Process Biogas Management

Center Enamel’s Double Membrane Biogas Holders are meticulously engineered to handle the gas output typical of continuous sludge digestion, maximizing the efficiency and safety of methane recovery for plant reuse.

Reliable Gas Buffer and Pressure Management

Sludge digestion processes often produce biogas with natural variability due to feeding schedules and temperature fluctuations. The balloon's design provides a flexible and dynamic gas reserve capacity that can dynamically expand and contract to accommodate the 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 internal energy offset of the treatment plant.

Fugitive Emission and Odor Control

The system acts as a crucial hermetic seal over the digester, which is paramount for both maximum gas capture efficiency and fugitive emission control (preventing the release of methane). Furthermore, the sealed design significantly reduces the odor emissions associated with sludge digestion, ensuring better environmental performance and compliance with local regulations.

Support for Aluminum Dome Roofs

Where maximum structural integrity and corrosion resistance are required for the digester tanks—especially critical in environments dealing with corrosive sludge and gas—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 long-term corrosion protection and structural support for the entire digester tank structure, enhancing overall system durability.
