The characterization of biogas plant 

(no need to build cement pond,*0years' use life)

1. The  inner  biogas digester of  diaphragm is made of high-strengthened, high-elastic synthetic engineering diaphragm and of perfect anti-acid and anti-corrosion ability. Its capacity of absorbing the ambient heat and storing it is *0 % higher than that of other material.

2. The biogas digester is made by adopting a technology of combining internal digester and external protector.The outer protector is made of FRP which can be used for about ****0years. In this way, it not only minimizes the possibility of doing damage to the internal digester, prolong its life span, and also create a complete oxygen-free room for anaerobic microorganisms to do fermentation, which in return increases the biogas output ratio.
