What Are the Reasons for Membranes for Flexible Biogas and Water Storage Systems?

SATTLER PRO-TEX biogas membranes are so-called MLCs (Multi-Layer Composites) whose components and structure are designed to meet the requirements of the biogas industry. Compared with common PVC-coated tarpaulins, biogas membranes guarantee reduced methane permeability and high chemical resistance. SATTLER PRO-TEX offers technical fabrics for a wide range of applications, from lightweight Type I inner membranes for gas storage to heavy Type IV outer membranes.What Are the Reasons for Membranes for Flexible Biogas and Water Storage Systems?  The structural core of the membrane consists of high-strength polyester yarns that carry the static forces of a building. The polyester-woven base cloth is stabilized and protected by multiple layers of PVC, especially for biogas applications. The surface of the membrane is then sealed with a specific lacquer. As a result, the biogas membranes by SATTLER PRO-TEX offer the lowest possible biogas permeability, high resistance to aggressive substances contained both in the biogas and the condensate, as well as excellent weathering resistance and a long lifespan.SATTLER PRO-TEX biogas membranes are easily recognizable thanks to their embossing. Our fabrics are available in different tensile strengths, with or without a flame-retardant finish. Our products are constantly evolving to incorporate new developments. One of these is our “anti-browning” feature, which significantly reduces the brownish discoloration of the membranes in biogas plants.The supply of drinking water has the highest priority in cases of environmental disasters or other crises. Flexible tanks guarantee quick supply and swift transport options for clean drinking water.The sturdy membranes for industrial water by SATTLER PRO-TEX allow for manifold solutions to store and transport water in flexible tanks, be it for agricultural and industrial applications or in emergency situations.

Inner membranes are used both to store the biogas in a so-called double membrane gas holder and to serve as housing for biogas bags mounted on buildings or steel or concrete tanks. SATTLER PRO-TEX biogas inner membranes are flexible and reliable functional fabrics, making them ideal for biogas storage applications.Liquid manure, waste water tanks, and silo containers do not usually spread pleasant smells and should not be unnecessarily filled up with rainwater. Biogas roofs made of membranes are a highly efficient solution to both problems: the surroundings are shielded from smells to the greatest possible extent, while the cover prevents rainwater infiltration. SATTLER PRO-TEX biogas membranes are also highly resistant to aggressive substances that can develop in the condensate.

Double Membrane Biogas Balloon/ holders are used for biogas storage. It’s mounted tightly on the roof of the Digester and separated sphere on surface of Land. What Are the Reasons for Membranes for Flexible Biogas and Water Storage Systems?  The Biogas holder system has a double membrane structure.

Frequently Asked Questions

A tensile fabric structure comprises a tensioned fabric membrane roof supported by structure usually made of steel, aluminium or timber. Tensile Fabric Structures (Lightweight) structures are architectural and engineering creations known for their low mass compared to the applied loads. They encompass various forms such as tensile structures, frame-supported structures, air-supported structures, air-inflated structures, cable net structures, cable-and-strut structures (also called tensegrity), geodesic dome structures, and grid shells. These structures are celebrated for their material efficiency and are widely used in architecture and engineering due to their ability to offer strength and stability while keeping weight to a minimum, making them versatile for various applications.

There are two basic building blocks of anticlastic tensile structures: the Saddle and the Cone. The Saddle is a hyperbolic paraboloid which means that it is a surface made of two high points and two low points. The geometry of the surface is orthogonal or made by the warping of a rectangular grid. The Cone is like a volcano shape using a radial geometry created by radians and hoops to create surfaces. These two forms can be combined to create an infinite number of permutations much like the circle and the square in classical architecture. Synclastic forms such as Domes and Flat panel membranes are also offered.

Various fabric materials are used in the construction of tensile fabric structures, each chosen for its specific characteristics and suitability for the intended application. At J & J Carter we use four different types, PVC coated Polyester, PVC coated Glass Fibre, Silcone coated Glass Fabric, and PTFE coated Glass Fabric. For more information on the different types of materials, visit our Tensile Fabric Materials page which breaks down each fabric and provides a helpful comparison graph.

This can vary depending on the design and specification of the materials and on other factors such as maintenance, cleaning and location. Typically, a PVC membrane would last around 20-25 years and a PTFE structure would last in excess of 30 years. Fabric technology, design and manufacturing techniques are advancing all the time and we’re seeing the lifespans of tensile structures increase as a result.

Integrating tensile structures with regular buildings involves a strategic approach to seamlessly combine architectural and structural elements. They can be used as curtain walls either as building cladding for atriums or courtyards in intense solar regions or as shading systems in conjunction with glass curtain walls. They can be used as canopies that join on the outside of buildings to give flair at entrances and as covered walkways. They can be stand alone pavilions that act as objects in the streetscape. They not only provide shelter but also introduce natural light and enhance the aesthetics of a building.
