A double membrane biogas holder is a flexible, dome-shaped gas storage system commonly installed above digesters in anaerobic digestion plants. It is composed of two distinct membranes:
The outer membrane, which maintains structural form through continuous low-pressure air supply.
The inner membrane, which expands and contracts depending on the volume of stored biogas.
This intelligent dual-layer system enables real-time gas accumulation and discharge while offering mechanical protection against wind, rain, and environmental conditions. These holders are typically mounted on concrete foundations, steel tanks, or digesters, functioning as both a biogas buffer and a pressure stabilizer.
Unlike rigid gas tanks or pressurized steel containers, double membrane gas holders allow for volume flexibility, safe pressure equalization, and visual monitoring, making them ideal for livestock wastewater treatment systems that rely on anaerobic digestion for methane production.
Livestock farming in Myanmar has grown significantly in recent years, leading to increased environmental pressure from manure runoff and organic-rich wastewater. As part of sustainable agricultural practices, anaerobic digestion systems are being deployed to treat livestock effluent, reduce greenhouse gas emissions, and generate renewable biogas energy. Double membrane biogas holders play a critical role in these systems by offering:
In livestock wastewater treatment, the volume of produced biogas fluctuates depending on the digestion rate and organic load. Double membrane gas holders provide a dynamic storage solution, expanding and contracting as needed. This helps maintain optimal pressure in the system and avoids gas loss or structural damage.
Traditional gas storage systems are prone to overpressure, which poses serious explosion risks. The double membrane holder, with its integrated pressure control unit, continuously adjusts the internal pressure, preventing system failure and ensuring safe, sealed storage of methane-rich gas.
In hot and humid regions like Myanmar, outdoor installations are exposed to intense UV rays and monsoon rains. Center Enamel’s double membrane biogas holders are constructed using UV-resistant and weatherproof polymer fabrics, offering long-term durability in tropical environments.
While these gas holders are particularly effective for livestock wastewater treatment, their application extends far beyond. Center Enamel’s double membrane biogas holders are integral to various chemical, environmental, and renewable energy projects, including:
Used in pig, poultry, and cattle farms to store biogas from anaerobic digestion of manure and bedding material. The stored gas is utilized for heating, cooking, or electricity generation.
Municipal wastewater treatment plants that operate sludge digesters benefit from biogas storage systems for gas buffering, CHP supply, and carbon footprint reduction.
Breweries, dairies, and food processors use anaerobic digesters to treat high-COD waste. Double membrane holders ensure stable gas delivery to bioenergy systems.
Chemical manufacturing facilities can install anaerobic reactors to treat organic-rich effluents. Our holders provide secure biogas containment, even when volatile organic compounds are present.
Some double membrane holders are used to store landfill gas, captured from decaying waste, and later used as an energy source or flared off for safety.
