Tank Rim-mounted Double Membrane Biogas Holder

The double membrane gas holder: Tank Rim-Mounted Double Membrane Biogas Holder
Tank Rim-Mounted Double Membrane Biogas Holder can also be supplied to provide a storage volume directly on top of a tank wall. In this configuration, the product can offer notable investment savings by eliminating the requirement for a traditional pressure-retaining tank roof and removing the requirement for a separate concrete base for the biogas holder itself.
Tank rim-mounted double membrane biogas holders can be installed onto both concrete and steel tanks, provided that the forces imposed onto the shell have been accommodated into the tank design.
In its simplest format, the two membranes are anchored to the top of the tank wall, with the gas containment formed between the inner membrane and the tank shell and liquid contents.  The Outer Membrane is air supported and permanently inflated. Containment volumes can be provided to suit the requirements, with the height of the structure being determined as a product of the volume requirement and tank diameter.  As the stored volume of gas is depleted, the inner membrane would float on top of the tank liquid contents.
More complex variations of the tank rim-mounted double membrane biogas holder may be required. These may be configured with a central support column and a system of supporting ‘under belts’ that span from the column to the tank wall to support the inner membrane when the containment is depleted.   

Application of tank rim-mounted double membrane biogas holder
Livestock farm, Brewery wastewater treatment, Beer wastewater treatment plant, the paper mill wastewater treatment, urban sewage treatment, garbage disposal, food waste treatment, , Food wastewater treatment, crops’ waste treatment , food factory sewage treatment, etc.

Benefits of tank rim-mounted double membrane biogas holder
MONDES's tank rim-mounted double membrane biogas holders are exclusively manufactured from advanced structural fabrics and designed as membranes to provide both structural (climatic) stability and impermeable gas storage. No metals are used, except for the anchorage connecting the membranes to a concrete foundation slab.
 Our tank rim-mounted double membrane biogas holders are provided with full instrumentation to measure and control the storage process. Our Biogas holders can be used in (e.g.) solid waste processing facilities, sewage water and sludge treatment facilities, agricultural waste treatment projects, and agricultural- and industrial biogas installations.
