Integrated reactor

Biogas anaerobic digester with membrane gas holder/

Gas production and gas storage integrated reactor



Both biogas digester and flexible double membraner gas holder on the top of the reactor constitute the Gas Production and Gas Storage integrated System. The integrated biogas device is currently the mainstream mode of construction in European countries with a wealth of successful experience.  98% of the biogas projects builted in recent years are heat, electricity and fertilizer cogeneration mode, and the 80% of which adopt integrated anaerobic reactor.



Part 1.

Biogas digester

Biogas digester is a kind of assembled tank made of special anti-corrosion processed steel, polymer composite sealing materials, self-locking bolt assembling materials. The assembled tank is used for the storage of gas/liquid/solid in sewage treatment, biogas engineering, food storage and other industries. In biogas engineering, assembled tank is an important equipment for various of organic matter fermentation.

E-coating and P-coating processed steel sheet


Part 2.

Double membrane biogas holder:

Double Membrane Gas Holder/Gas storage Cabinet is a durable air supported structure specifically designed for the purpose of biogas storage. The biogas special-used membrane material is made of highly tear-resistant and anti-corrosion polyester fabrics.

Double membrane gas holder can be used as an independent gas storage structure, or be installed as part of the anaerobic digestion system.


Membrane material:



Advantages of integrated reacter:

(1)  Small space required, save 30% of construction area;

(2)  Substitute for the split type gas holder, save construction cost 15%;

(3)  Short period of construction, shorten the construction period of 50%;

(4)  Run normally in winter cold area, gas holder does not freeze.
