Why double membrane digester cover better than the traditional one?

Biogas can be 100% used, the inner biogas can be totally squeezed out which is hardly to achieve by the traditional one.
In light weight: It weighs only a small percentage than the traditional one. This does great good for make, transportation, installation, etc. And saving a lot of construction time and material cost.
No need to maintain for long: For the membrane field is made of the super anti-corrosion material, and can last more than 15 years in the biogas circumstance. Meanwhile, it is well welded by hot-melted materials, so we do not have to do regular maintain when use membrane storage.
It saves much time and labor: For it is small and light, also the membrane field has been well-shaped in factory, so the on-site installation will just cost 1-2 days.
Saving money: From the mentioned above, we can know that the total cost is lower than that of the traditional one.
Anti-freezing: For there is no water in the inner structure, there is no need to worry about the frozen problem in the cold area.
Keep warm: As we know, air is the perfect medium to keep warm. So the air between two-layer membrane makes the system warmer than the traditional one.
Artistic: The main color of the membrane is grey white, so it can easily be matched. Meanwhile, the whole structure is designed to be spheroidal, and this arise the sense of beauty.
Comparatively safe when accident happens: Anyway, biogas is flammable gases, if by any chance explosion happens, it will not produce so much injury pieces as other hard material made storage.

10. Easily repair: If unforeseeable things happened, most of the maintenance can be easily done at present. For example,When gas leaking, it only need a small patch.

11.Easily remove: If customer needs to remove the system, it can be easily achieved. There is no need to worry about the by-way produced useless and difficult transportation. From this point, it is better than any kind of traditional design.

12.Fire protection: The material of membrane field is non-flammable, the fire protection grade reach the Euro-standard B.

Detailed information:

For the knowledge of membrane structure biogas storage various from customer to customer, and even company in this trade are not of the same standard. So we insist on our “sale and service” principle of “measure and make”, reasonable recommendation and factory visiting”.

Our biogas specific membrane has been well welded and it won’t be cracking and air leaking like other products after long-time stress.

Main material:

Biogas specialized membrane material is made of imported high-strengthened, high-elastic synthetic engineering membrane and of perfect anti-acid and anti-corrosion ability, so we do not have to do regular maintain when we use membrane storage tank.

The biogas specific membrane has been widely used in energy treatment, sewage treatment, agriculture waste, landfill site and other industries.

The service life is over 15 years.

Fundamental consist of this system:

1. Main material: Biogas special-used membrane material is made of highly tear-resistant polyester fabrics and generally it can be divided into inner membrane and outer membrane.

2. Gas in and out system: standard pipeline

3. Boost pump: make to order

4. Observation window: standard stainless steel

5. Probing system: make to order

6. Auto-control system: make to order

7. Alarming system: make to order

8. Display system: make to order

9. Security: safe by water seal and electric decompression

10. Functional tank: different kinds of metal materials

11. Different kinds of pipe lines, valves and sealing

Our biogas holder tank is at the top of the fermentation cylinder, and can be used as a cover.
