How to Choose a Double Membrane Biogas Holder?

A double membrane biogas holder is a type of biogas storage tank, which is further divided into integrated  double membrane biogas digester tank and independent double membrane biogas digester tank with different characteristics and uses. It is suitable for biogas, air, carbon dioxide, etc., and can resist biogas corrosion, UV radiation, and microorganisms. The structure is composed of bottom film, inner film, outer film, etc.

The bottom film, inner film, and outer film of double membrane gas holder are designed using specialized membrane software based on various shapes and specifications, and then processed using a large-scale hot press in a dust-free workshop. The large equipment hot presses the separated film pieces into a whole, ensuring the high requirements for heat and seam gas tightness, and also ensuring the same lifespan as the material, guaranteeing durability.

With the increasing emphasis on environmental protection by the country, double membrane gas holder in biogas plant have been increasingly used in rural breeding farms for manure treatment, biomass gas, leachate treatment from garbage decomposition, and industrial wastewater treatment. At the same time, the application of double membrane roof is also becoming more and more extensive. However, with the increasing market demand, more and more double membrane bio digester tank manufacturers have entered the industry. So, how to choose a double membrane biogas holder?

This is closely related to the service life of the dual-film gas storage system, whether it can operate stably during use, whether the maintenance process is simple and easy to learn, and whether it can solve customers' worries in detail. It is absolutely not advisable to choose double membrane gas holders solely based on price and surface configuration.

Some customers exaggerate the configuration of the entire biogas storage system in order to get a lower overall price. For example, they overemphasize the role and price of material thickness: in fact, the performance of materials is composed of various aspects such as base fabric strength, latitude and longitude of the base fabric, formulation of the surface coating, and coating process. Thicker materials are not necessarily better. In fact, to judge the quality of materials, it is necessary to look at inspection reports and parameters such as tensile and tear resistance.

Is it better to have a more expensive configuration for the double membrane gas storage tank system? Of course not. The selection of the configuration depends on the use environment, gas production volume, pipeline flow rate, on-site control conditions, and subsequent use of biogas for the project. Imported equipment is not always suitable. For projects with a good use environment, domestically produced equipment can fully meet the requirements. Of course, if the use environment has strong corrosiveness, the anti-corrosion performance must be considered first.

When making a configuration list with clients, YHR Tanks will have a detailed understanding of the client's gas production matrix, gas production volume, subsequent use of biogas, and the surrounding use environment of the biogas project, and recommend suitable configurations based on the client's actual situation. This way, clients will not spend more money and can still buy suitable double membrane biogas holders.
